  • Microalgal potential for nutrient-energy-wastewater nexus: Innovations,
           current trends and future directions
    • Authors: Sandeep Panda, Srabani Mishra, Ata Akcil, Mehmet Ali Kucuker
      Abstract: Energy & Environment, Ahead of Print.
      Agricultural, domestic and industrial activities contribute in releasing several organic and inorganic substances into the water streams that result in environmental pollution. Biological treatment of industrial and domestic wastewater using Activated Sludge Nutrient Removal (ASNR), the conventional process, is well known; however, it is relatively expensive due to the requirement for high energy inputs. Microalgal applications have been gaining interest as they offer potential cost-effective measures for the treatment of wastewater in the peri-urban and rural areas. Such systems provide an interesting tertiary biological treatment method where valuable biomass is produced with simultaneous uptake of nutrients such as nitrogen and phosphorous with reduction in coliform bacteria, heavy metals, chemical and biochemical oxygen demand (COD & BOD) and the removal/degradation of xenobiotic compounds etc. This paper provides a systematic review on the current microalgal applications (phycoremediation) for wastewater treatment with advanced information on their role towards nutrient recovery and energy (biogas) production under the third generation biorefinery concept. The use of advanced algal pond systems for wastewater treatment including pollutant degradation, microalgal cultivation and employing such facilities for biogas production in view of technology applications is emphasized. This inter-linked network indicating microalgal role into the Nutrient-Energy-Wastewater nexus with future directions and concluding remarks are discussed.

  • Role of high technology exports for energy efficiency: Empirical evidence
           in the context of Gulf Cooperation Council countries
    • Authors: Rida Waheed, Suleman Sarwar, Zouheir Mighri
      Abstract: Energy & Environment, Ahead of Print.
      This article explores the impacts of high technology exports on energy consumption, energy intensity, and carbon intensity for a panel of six GCC economies covering a period of 1990 to 2017. For detailed empirical analysis, we employ panel techniques to explore the linkages between high technology exports and energy efficiency in GCC countries. The empirical results demonstrate that high technology exports help to reduce overall energy demand with −0.154% and energy intensity with −0.254% in GCC countries. Notably, we observe that effects on technology exports on carbon intensity are significantly lower in magnitude with −0.010%. Notably, the long empirics are in consistent with achieving the Sustainable Development Goals (SDG's) of GCC countries (cleaner and affordable energy, environmental awareness, climate change action, etc.). The findings suggest that new and innovative energy conservation policies should be introduced to promote energy efficient equipment’s and technologies for cleaner and greener growth.

  • Analysis on complementarity between a CO2 tax and an emissions trading
           system to reduce industrial emissions in Chile
    • Authors: Cristian Mardones
      Abstract: Energy & Environment, Ahead of Print.
      This study aims to analyze the behavior of Chilean industrial sources when a CO2 tax, an emissions trading system with a total reduction target of 30%, or both instruments simultaneously are applied. For the above, an optimization model is built that is then calibrated with firm -level data obtained from the Annual National Industrial Survey (ENIA). Specifically, the model assumes that industrial sources have the option of maintaining their original emissions, replacing their current fuels with less polluting ones to pay fewer taxes and/or trade of emissions in a carbon market. The results show that to reduce emissions by at least 30% a tax close to US $17.5/tCO2 could be applied with a total cost of US $106 million, but it would be better to apply an emissions trading system with a similar price because the total cost would be US $21.3 million. If both economic instruments are applied together, the total cost of reduction is higher than when the instruments are implemented independently. Thus, it is concluded that Chile could move from a CO2 tax to an emissions trading system in order to reduce the costs of its environmental regulation.

  • The role of shale gas in shaping the U.S. long-run CO2 emissions
    • Authors: Y.-H. Henry Chen, John M Reilly, Sergey Paltsev
      Abstract: Energy & Environment, Ahead of Print.
      The shale gas boom in the U.S. has lowered the U.S. CO2 emissions in recent years mainly through substitution of gas for coal in power generation. Will the shale gas boom reduce the emissions in the long-run as well' To study this, we consider a counterfactual without the shale gas boom based on a general equilibrium modeling for the 2011 U.S. economy. To enhance the power sector modeling, the supply responses of coal-fired and gas-fired generations are calibrated to existing research. We find that if gas prices remain at 2007 levels in 2011, only a model setting that allows very little reduction in electricity demand, reflecting a short-run demand response, generates an increase in economy-wide emissions. For all other cases, the higher gas price under the counterfactual will have a dampening effect on economic activities and consequently lowers economy-wide emissions, even though the power sector emissions may increase due to the gas-to-coal switch. In other words, without any policy intervention, although the shale gas boom could reduce emissions in the short run, it may lead to higher emissions in the long run if the low gas prices persist. Our finding suggests that extrapolating the current decline in emissions due to the shale gas boom to the distant future could be misleading. Instead, if curbing emissions is the goal, rather than depending upon the cheap gas, policies and measures for cutting emissions remain imperative.

  • Regional dimensions of the South Korean water-energy nexus
    • Authors: Jinyoung Lee, Hana Kim
      Abstract: Energy & Environment, Ahead of Print.
      The linkage between water and energy, the water-energy nexus, is site specific. An integrated management approach to both resources begins with understanding a region’s water-energy nexus. This study built an inventory of water and energy consumption in 17 South Korean regions at each stage of the urban water cycle from 2012 to 2017, estimated the water-related energy intensities, and compared those values across regions. Additionally, this study conducted a series of regression analyses to identify the influences of various factors on water-related energy consumption. This study found regional variance in the total energy intensity as well as in the energy intensities at different stages of the water cycle. Both energy consumed and energy intensities generally increased over the study period. The findings show that greater attention should be paid to energy consumption in the water sector, especially in the wastewater treatment sector. In addition, the regression analyses revealed that management of energy intensity is the most impactful way to reduce energy consumption in the water sector. The positive impacts on water pollution and water consumption also bolster the necessity of water conservation efforts. This study presents regional priorities related to the water-energy nexus and provides water-related energy intensity benchmarks that local governments can use. The findings highlight the necessity of an integrated approach to water and energy.

  • Are the intensity of energy use, land agglomeration, CO2 emissions, and
           economic progress dynamically interlinked across development levels'
    • Authors: Munir Ahmad, Heng Li, Muhammad Khalid Anser, Abdul Rehman, Zeeshan Fareed, Qingyou Yan, Gul Jabeen
      Abstract: Energy & Environment, Ahead of Print.
      Although urban agglomerations have introduced substantial contributions to the economies around the globe, it has also led to the serious environmental challenges. However, this situation may vary across the development levels. The existing knowledge offers a gap in terms of both theoretical and empirical grounds. The Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) is previously not known to incorporate land agglomeration and the intensity of energy use. Besides, the investigation of linkages among the variables of interest across the development levels within a country is not known to be considered by the existing knowledge. This study systematically investigates the heterogeneous dynamic causality among the intensity of energy use, land agglomeration, carbon dioxide emissions (CO2), and economic progress across the development levels in the Chinese economy, considering 29 provinces for the period 2000 to 2018. To this end, a long-term co-integration association is tested and found existent among the variables of interest. A dynamic common correlated effects mean group approach is applied for impact analysis. The key findings include: The impacts of economic progress and land agglomeration on CO2 are found positive and significant in the country panel and western zone of China (WZC). It turned to be neutral in the case of the central zone of China (CZC) and significantly negative in the eastern zone of China (EZC). To this end, economic progress presented a ‘development ladder-based CO2 mitigation effect,’ while the land agglomeration exposed the ‘land agglomeration ladder-based CO2 mitigation effect’. Further, the causalities extracted are: first, economic progress is found in positive bilateral linkages with the intensity of energy use and land agglomeration for all the panels. Second, a positive and unilateral causal bridge is found operating from land agglomeration to the intensity of energy use and from the intensity of energy use to CO2. Third, a unilateral linkage of mixed nature is exposed to exist from land agglomeration to CO2, with positive causal links for country panel and WZC, negative causal links for EZC, while a neutral linkage is found for CZC. Fourth, a bidirectional link with mixed causalities appeared in the country panel and WZC. Economic progress increased CO2 in WZC. Next, a negative bilateral link is observed between the two variables in EZC. Additionally, this link remained neutral in CZC. Based on empirics, it is revealed that the development level matters in determining the links among the variables of interest.

    • Authors: Chun Chih Chen
      Abstract: Energy & Environment, Ahead of Print.
      Taiwan intends to be nuclear free by 2025. This study employs the Lotka–Volterra competition model for sustainable development to analyze the emissions–energy–economy (3Es) issue to make appropriate policy suggestions for a nuclear-free transition. It also offers a new approach to naming the 3E relationship. The literature review shows that the environmental Kuznets curve accompanies the feedback and conservation hypotheses. In the 3E dynamics relationship analysis, the model shows a good mean absolute percentage error (

  • Effect of process conditions on the surface properties of biomass chars
           produced by means of pyrolysis and CO2 gasification
    • Authors: Junaid Ahmad, Stergios Vakalis, Francesco Patuzzi, Marco Baratieri
      Abstract: Energy & Environment, Ahead of Print.
      Biomass char is defined as the carbonaceous by-product of biomass pyrolysis or gasification and is an undesired by-product that is disposed as a waste, usually at a very high cost. Chars have interesting characteristics like high carbon content and high porosity. These characteristics can make attractive the utilization of biomass char for alternative and innovative applications, e.g. as precursors for activated carbons or as filtering mediums. In this framework, this present work focuses the attention on the surface properties of char which is a key parameter for the evaluation of its applicability in adsorption applications. The combination of three main variables has been considered: the carrier gas (nitrogen or carbon dioxide), the temperature (set at 500°C, 700°C and 900°C) and the initial heating rate (10°C min−1, 30°C min−1 or 50°C min−1). Maximum heating values are observed at 700°C for the case of inert atmosphere (pyrolysis) and the values reduce slightly for the case of CO2 gasification. On the contrary, CO2 gasification has a positive effect on the porosity of the biomass chars. This present research has the scope to provide a first insight on the effect of operating conditions on the optimal char characteristics for the utilization of biomass char as a cheap alternative for filters and adsorbents. An interesting future potential transition of existing biomass CHP facilities would be the evolution into biorefineries, in accordance with the new mandates about Circular Economy.

  • Renewable and non-renewable energy consumption and economic growth in the
           US: A Markov-Switching VAR analysis
    • Authors: Emrah Ismail Cevik, Durmuş Çağrı Yıldırım, Sel Dibooglu
      Abstract: Energy & Environment, Ahead of Print.
      We examine the relationship between renewable and non-renewable energy consumption and economic growth in the United States. While the regime-dependent Granger causality test results for the non-renewable energy consumption and economic growth suggest bi-directional causality in both regimes, we cannot validate any causality between renewable energy consumption and economic growth. The US meets its energy demand from non-renewable sources; as such, renewable energy consumption does not seem to affect economic growth. Given the efficiency and productivity of renewable energy investments, we conclude that it is worthwhile to consider renewable energy inputs to replace fossil fuels given potential benefits in terms of global warming and climate change concerns. In this regard, increasing the R&D investments in the renewable energy sectors, increases in productivity and profitability of renewable energy investments are likely to accrue benefits in the long run.

  • Consumers’ heterogeneous preferences toward the renewable portfolio
           standard policy: An evaluation of Korea’s energy transition policy
    • Authors: Jihee Lee, HyungBin Moon, Jongsu Lee
      Abstract: Energy & Environment, Ahead of Print.
      The low electricity tariff in Korea compared with other developed countries renders renewable energy expansion more challenging as its costs are higher than those of traditional power generation such as thermal and nuclear power. An increase in the electricity tariff is required to help the expansion of renewable energy and accelerate the energy transition. It is therefore necessary to understand public acceptance of the renewable portfolio standard (RPS) policies implemented by the Korean government to expand renewable energy. This study analyzes public’s heterogeneous preferences of renewable energy policies and identifies the determinants of people’s divided reactions to the policy. This study also forecasts the change in the degree of public acceptance of renewable energy expansion until 2030 and provides suggestions for the enhancement of public awareness and acceptance of the RPS plan. The simulation analysis shows that a sharp decline in the public’s acceptance rate is to be expected when the renewable energy expansion target becomes more challenging in 2025. The drastic change in acceptance is attributed to the electricity tariff spike. We conclude that the government should prepare to address the severe backlash from the public against the increase in electricity tariff to have a successful renewable energy policy.

  • Energy and resources cooperation for greenhouse gases emissions reduction
           of industrial sector
    • Authors: Parakram Pyakurel, Laurie Wright
      Abstract: Energy & Environment, Ahead of Print.
      Energy and resources cooperation has a great potential of reducing greenhouse gases (GHG) emissions of companies, especially in industrial and business parks where facilities are located in geographical proximity. Such cooperation could cut emissions without significant impact on profit, and in some cases, may even reduce costs by decreasing waste generation and improving energy efficiency. This paper combines similar themes of industrial symbiosis, sharing economy and circular economy to formulate a single robust concept of energy and resources cooperation. A framework and methodology for mass implementation of energy and resources cooperation is proposed by integrating disparate fields of industrial ecology, business studies and industrial investments. Furthermore, an approach of enhancing such cooperation is proposed which involves an establishment of a specialized Cooperation Development and Management Company. Finally, research agenda is set out to capitalise the developments of industry 4.0 and peer to peer sharing for energy and resources cooperation.

  • Differences in the effects of China’s new energy vehicle industry
           policies on market growth from the perspective of policy mix
    • Authors: Yongqing Xiong, Shufeng Qin
      Abstract: Energy & Environment, Ahead of Print.
      Regarding the characteristics of policy mix and its effectiveness, no complete consensus currently exists. This paper divides the new energy vehicle (NEV) industry policies issued by the Chinese government from 2009 to 2018 into two types: the supply-side and demand-side policy mix. From the three dimensions of comprehensiveness, consistency and balance, we applied the state space method to construct a time-varying parameter model and analyzed the differences in the overall and dynamic impact of the NEV policy mix characteristics on market growth. The results show that the three characteristics differ in their overall impact: comprehensiveness has the largest impact, followed by consistency, and balance has the smallest impact. The dynamic impact of the comprehensiveness and consistency characteristics of the two types of policy mix fluctuates greatly and presents clear differences in the stage effect. The dynamic impact of the balance characteristic is relatively stable, but this characteristic has little dynamic impact on market growth. The NEV industry policy design should fully consider the characteristics of the policy mix and the differences of this policy mix in terms of market development stage and region.

  • Offshore wind energy status, challenges, opportunities, environmental
           impacts, occupational health, and safety management in India
    • Authors: J Charles Rajesh Kumar, D Vinod Kumar, D Baskar, B Mary Arunsi, R Jenova, MA Majid
      Abstract: Energy & Environment, Ahead of Print.
      Offshore wind is at its infancy in terms of technology and capacities in India. The Ministry of New and Renewable Energy (MNRE) announced medium and long term offshore targets of 5 GW and 30 GW by 2022 and 2030, respectively. The location of the first offshore wind park has recently been identified, and the Solar Energy Corporation of India (SECI) has signed a contract with the Government of Gujarat to establish the 1000 MW of offshore wind energy capacity by 2019. To achieve the ambitious targets, India will require demand and resources planning, and policy support at an unprecedented scale. The MNRE notified the country’s offshore wind energy policy in 2015, and draft offshore wind energy lease rules in 2019. In this paper, several offshore wind energy challenges have been identified, and a clear policy road map and effective support schemes required to trigger offshore wind development activity for medium to long term are suggested. The environmental consequences of European offshore wind farms are assessed to optimize future monitoring of offshore wind programmes in India. Furthermore, the occupational health and safety management requirements are highlighted to ensure that the accidents, vulnerabilities, and hazards are avoided. The research and development (R&D) considerations are provided to assist policymakers, potential investors, stakeholders, designers and manufacturers, contractors, professional advisers, and wind farm developers in their decisions and planning.

  • Comprehensive analysis of the thermohydraulic performance of cooling
           networks subject to fouling and undergoing retrofit projects
    • Authors: Hebert Lugo-Granados, Lázaro Canizalez-Dávalos, Martín Picón-Núñez
      Abstract: Energy & Environment, Ahead of Print.
      The aim of this paper is to develop guidelines for the placing of new coolers in cooling systems subject to retrofit. The effects of the accumulation of scale on the flow system are considered. A methodology to assess the interconnected effect of local fluid velocity and fouling deposition is developed. The local average fluid velocity depends on the water flow rate distribution across the piping network. The methodology has four main calculation components: a) the determination of the flow rate distribution across the piping network, b) the prediction of fouling deposition, c) determination of the hydraulic changes and the effect on fouling brought about by the placing of new exchangers into an existing structure, and d) the calculation of the total cooling load and pressure drop of the system. The set of disturbances introduced to the system through fouling and the incorporation of new coolers, create network responses that eventually influence the cooling capacity and the pressure drop. In this work, these interactions are analysed using two case studies. The results indicate that, from the thermal point of view, the incorporation of new heat exchangers is recommended in series. The limit is the point where the increase of the total pressure drop causes a reduction in the overall volumetric flow rate. New coolers added in parallel create a reduction of pressure drop and an increase in the overall water flow rate; however, this increase is not enough to counteract the reduction of fluid velocity and heat capacity removal.

  • CO2 absorption of anhydrous colloidal suspension based silica nanospheres
           with different microstructures
    • Authors: Yudong Ding, Liheng Guo, Xiaoqiang Li, Qiang Liao, Xun Zhu, Hong Wang
      Abstract: Energy & Environment, Ahead of Print.
      Liquid absorption and solid adsorption technologies have been researched and reported widely for CO2 capture. Combining the advantages of these two capture materials, a novel anhydrous colloidal suspension was synthesized by dispersing amine-modified microporous silica nanospheres in 2-[2-(dimethylamino) ethoxy] ethanol. In this study, solid, hollow, and porous silica nanospheres with different internal pore structures were synthesized and characterized. The effects of the silica nanosphere microstructures on diethylenetriamine loading and CO2 absorption in anhydrous colloidal suspensions were studied. Due to a more developed pore structure, the hollow and porous silica-based absorbents possessed stronger amine loading capacities compared to solid silicon-based absorbent, and the best absorption performance was an absorption capacity of 1.2543 mmol/g at a pressure of 150 kPa and a temperature of 300 K. The results indicated that pore structure had a significant influence on the absorption property, and the porous silica-based absorbent was more favorable for CO2 absorption than solid and hollow silica-based absorbents. Moreover, the pseudo-second-order model was successful in predicting the CO2 absorption process in colloidal suspensions.

  • Do energy efficiency building codes help minimize the efficiency gap in
           the U.S.' A dynamic panel data approach
    • Authors: Bishwa S Koirala, Alok K Bohara
      Abstract: Energy & Environment, Ahead of Print.
      This study estimates the effects of energy efficiency policy in the residential sector using panel data of 48 contiguous states starting from 1970 to 2017. To avoid any unobserved heterogeneity and facilitate efficiency in estimation, this study employs a Dynamic Panel Data model with a two-step Generalized Method of Moments technique. The results suggest that energy efficiency policy for the residential sector has saved about 8.6 percent in energy consumption, which is about 22 percent of the total stated saving, leaving an energy efficiency gap of 1.5771 quadrillion Btu. Consistent with previous estimations, this study finds that theoretical saving amounts overestimate energy efficiency output and overinflate the increase in potential energy efficiency by about 32 percent. Since energy efficiency policy has failed to achieve the stated amount of saving in the residential sector, households have no incentive to adopt the energy efficiency policy, which has created an unusual gap in energy efficiency.

  • The impact of international sanctions on energy security
    • Authors: Jun Wen, Xinxin Zhao, Quan-Jing Wang, Chun-Ping Chang
      Abstract: Energy & Environment, Ahead of Print.
      This study first investigates different types of sanctions on energy security by employing data from a panel of target countries covering the period 1996–2014 and using the panel fixed effect model. Our evidence indicates that international sanctions do significantly negatively influence the energy security of target countries in some cases. Specifically, unilateral sanctions, U.S. sanctions, economic sanctions, and the intensity of sanctions have a significantly negative impact on energy security. However, plurilateral sanctions, EU sanctions, UN sanctions, and non-economic sanctions have no significant impact on the energy security of target countries. The results of endogeneity concerns are also consistent with the results of the basic regression analysis. Overall, our empirical findings merit particular attention from policy makers of target countries to ensure their energy security when facing international sanctions.

  • The spatial-temporal evolution and spatial convergence of ecological total
           factor productivity in china
    • Authors: Zhengda Li, Dong Li, Wanping Yang, Xiaoyan Qi
      Abstract: Energy & Environment, Ahead of Print.
      Based on the theory of strong sustainability, this paper evaluates the ecological environment from two aspects of ecological environment construction and ecological environment damage, and incorporates the ecological environment into the research framework of total factor productivity (TFP), and proposes a new ecological total factor productivity (ETFP) index, and studies the source of factors, spatial-temporal evolution and spatial convergence of the ETFP in China from 2001 to 2018. The results show the following: ETFP is driven by technological efficiency, and the stage fluctuation differentiation is obvious; the growth rate of the sub-factors of the “labor —energy — ecological environment construction — capital” decreases in sequence, and the contribution degree of the factors of “labor — ecological environment construction — energy — capital” keep decreasing in turn; the distribution pattern evolves from unipolar to bimodal. The path dependence of TFP on capital, labor and energy is relatively strong; There was a spatial convergence in china's provincial ETFP, and convergence speed was accelerated of 4.07% under Geo-economic weight matrix. Considering the influence of institutional factors, environmental decentralization and fiscal decentralization can put off the ETFP’s increasing speed, but the interaction between them can drive the ETFP’s growth.

  • New micronutrient biocomponents based on blackcurrant seeds pomace –
           Bench-scale kinetic studies
    • Authors: Katarzyna Chojnacka, Mateusz Samoraj, Łukasz Tuhy, Małgorzata Mironiuk, Konstantinos Moustakas, Anna Witek-Krowiak
      Abstract: Energy & Environment, Ahead of Print.
      In the present work new universal bench-scale plant for biosorption, useful in production of new micronutrient biocomponents, was described. The new installation enabling working in a fixed bed or stirred tank batch mode. Reactors may also be used in serial or parallel mode, which gives many application possibilities.Copper ions were selected as a sorbate for kinetic modelling. The results of the adsorption capacities of Cu(II) were 13.9 mg/g for fixed bed and 12.8 mg/g for stirred tank. During biosorption of Cu(II) ions from aqueous solution ion exchange and release of Ca(II), K(I), Mg(II), and Na(I) were observed. For kinetics description of stirred tank process pseudo-1st-and pseudo-2nd order models were used. For fixed bed process the Thomas, Yoon-Nelson, Adams-Bohart and Wolborska models were used. The use of blackcurrant seed residues as biosorbents enables the generation of new products from waste biomass, which can become an alternative to the traditional fertilizers with microelements. The presented technology is an attempt to reduce environmental impact of the conventional micronutrient fertilizers, which contain toxic chelators such as EDTA. Minimization of waste and maximization of product output makes it an efficient tool supporting cleaner production.

  • Emission profiling of a common rail direct injection diesel engine fueled
           with hydrocarbon fuel extracted from waste high density polyethylene as a
           partial replacement for diesel with some modifications
    • Authors: Kulandaivel Duraisamy, Rahamathullah Ismailgani, Sathiyagnanam Amudhavalli Paramasivam, Gopal Kaliyaperumal, Damodharan Dillikannan
      Abstract: Energy & Environment, Ahead of Print.
      A hydrocarbon fuel extracted from waste high-density polyethylene (WHDPE) by catalytic pyrolysis in a batch scale reactor is blended with diesel by 30% vol. (called as D70H30) is tested in a variable compression ratio engine equipped with a common rail system. Experiments were conducted at three compression ratios (16:1, 17.5:1, and 19:1) and exhaust gas re-circulation (EGR) rates (0%, 10%, and 20%) at the engine’s rated power to evaluate its combustion, performance and emission characteristics. The results revealed that, increasing the compression ratio resulted in higher peak cylinder pressure (PCP) and heat release rates (HRR). Introduction of EGR diminished both PCP and HRR peaks. The brake thermal efficiency of D70H30 blend was 4% lower than diesel at same operating conditions which got better at higher compression ratio without EGR. NOx emission was highest when injected at compression ratio 19:1 and at 0% EGR rate which was 6% and 3% higher than diesel and D70H30 blend operated at engine stock settings. In comparison with baseline diesel smoke opacity remained lower at all operating conditions, where lowest smoke emission was recorded at CR19 and at 0% EGR rate. UHC and CO emission followed the similar trend of smoke opacity. Whereas CO2 emission increased with compression ratio and reduced with induction of EGR. It can be concluded from the study that at higher compression ratio and low EGR rates D70H30 blend can be effectively utilized in a CRDi engine.

  • Measuring technical inefficiency and CO2 shadow price of Korean
           fossil-fuel generation companies using deterministic and stochastic
           approaches
    • Authors: Dong-Hyun Oh, JongWuk Ahn, Sinwoo Lee, Hyundo Choi
      Abstract: Energy & Environment, Ahead of Print.
      This paper measures the technical inefficiency and the shadow price of Korean fossil-fuel generation companies (GENCOs) between 2001 and 2016 at the firm-level. To obtain robust empirical results, this study employs both commonly used deterministic and stochastic estimation methods. The empirical results are as follows: the inefficiency estimates are approximately 0.09 (deterministic) and 0.08 (stochastic); the estimates of CO2 shadow price, in KRW/tCO2, are 82,758 (deterministic) and 49,830 (stochastic), which shows high volatility in the annual average shadow price. In addition, we find that the results of the deterministic method without any random errors show a large variation in the trends of technical inefficiency and shadow price, while the stochastic method with random errors yields only moderate volatility. Our empirical results are expected to assist policymakers in determining how much potential mitigation can be achieved through improved efficiency, and the range of the CO2 shadow price will contribute to more efficient policy tools.

  • On the nexus of CO2 emissions and renewable and nonrenewable energy
           consumption in Europe: A new insight from panel smooth transition
    • Authors: Huthaifa Alqaralleh
      Abstract: Energy & Environment, Ahead of Print.
      This study seeks, within the extended framework of the so-called environmental Kuznets curve (EKC), to analyse the nonlinear effect of economic growth and energy consumption on environmental pollution (measured by CO2 emissions) in 30 countries, over the period 2000 – 2018. The panel smooth transition regression (PSTR) model is used to allow such a relationship between variables in different economic regimes to be determined. According to the analysis results, this study strengthens the idea that the relationship can be described as a shaped business cycle, in which economic growth first increases environmental degradation, and then, after a certain growth (income) level has been reached, reduces it. This business cycle relationship suggests that environmental improvements will eventually occur as economies grow. Another implication of these results is the importance of using energy in a greener way to combat climate change and to sustain economic development.

  • Greenhouse gas emissions reduction by process intensification: Reactive
           distillation column with side decanter
    • Authors: Alexandra-Elena Plesu Popescu, Jordi Bonet, Joan Llorens
      Abstract: Energy & Environment, Ahead of Print.
      Direct hydration of cyclohexene to produce cyclohexanol is the industrial process with a lower raw material cost but with a quite expensive process. Large energy consumption is consequence of large cyclohexene recycle related with its unfavourable chemical equilibrium. This study corroborates that the Asahi process is a good candidate for intensification avoiding the cyclohexene recycle. Rigorous simulation shows that a single reactive distillation column, with a side decanter, operated at total reflux, allows overcoming the chemical equilibrium limitations as the product is continuously collected by the column bottoms and the heat of reaction is directly used to separate the product by distillation. The novel process is studied and compared to the classical Asahi process. An energy comparison with the available processes proposed in the literature is performed. Therefore, achieving more energy-efficient processes leads to lowering their environmental impact, thus decreasing the carbon dioxide emissions. Applying the proposed methodology for cyclohexanol production, more than 67,000 t CO2/y emissions can be avoided compared to the nowadays used classical process, thus the potential savings applying process intensification to the chemical industry are very large and worth further investigation.

  • Evaluation of the impact of energy utilization and PM on respiratory
           health in China
    • Authors: Changfeng Shi, Xinhui Liu, Min Gu, Qinghua Pang, Zhen Shi
      Abstract: Energy & Environment, Ahead of Print.
      The haze climate has seriously affected people’s lives in China, and one of the important causes is particular matter (PM). For further, PM also has a negative impact on human health, especially respiratory health. A modified two-stage EBM (Epsilon-based Measure)data envelopment analysis (DEA) model considering undesirable outputs was used in this study to explore the energy utilization, PM and respiratory efficiency evaluation in China. It is concluded that the total efficiency value of Beijing, Inner Mongolia, Shandong and Tianjin is high, while that of China’s other provinces is low. The overall efficiency of most provinces in the first stage is better than that in the second stage, and the efficiency difference between provinces in the second stage is more significant. There is a significant difference in PM efficiency between provinces, which needs to be managed by governments of different regions. Except for Beijing, Jiangsu, Inner Mongolia, Shandong and Tianjin, the efficiency of respiratory diseases in most provinces still needs to be improved. Therefore, it is suggested to optimize the industrial structure, accelerate the adjustment of energy structure, strengthen the treatment of air pollution and increase public expenditure on medical care, so as to improve residents’ respiratory health.

  • The wind energy potential in Kudat Malaysia by considering the levelized
           cost of energy for combined wind turbine capacities
    • Authors: A Albani, MZ Ibrahim, KH Yong, ZM Yusop, MA Jusoh, AR Ridzuan
      Abstract: Energy & Environment, Ahead of Print.
      This paper presents the wind energy potential at Kudat Malaysia by considering the Levelized cost of energy (LCOE) model for combined wind turbine capacities. The combination of small- and utility-scale wind turbines is the key to the success of the operation of a wind park in the lower wind speed region. In a combination approach, the small-scale wind turbines provide the power required by the utility-scale wind turbines to start the blade rotation. For this reason, the particular closed-form equation was modified to determine the LCOE of a wind park with combined turbine capacities. The modified LCOE model can be used as a basis for setting tariff rates or define the economic feasibility of wind energy projects with combined wind turbine capacities.

  • Decrease of energy demand of semi-batch distillation policies
    • Authors: Mariem Ferchichi, Laszlo Hegely, Peter Lang
      Abstract: Energy & Environment, Ahead of Print.
      Batch distillation (BD) has much higher energy demand than continuous distillation (CD). Different semi-batch distillation (SBD) policies, by which one part of the feed is continuously fed into a batch column, are investigated and optimised to minimise the energy demand. SBD has the advantage, that contrary to the batch distillation (BD), the liquid volume in the reboiler, can be kept constant, even at its maximal value. Usually, continuous feeding is performed into the reboiler (SBD1), but by shaping a feed plate in the batch column, it has not only a rectifying but also a stripping section. Several SBD policies differing in feeding location are studied by dynamic simulation and compared based on the specific energy demand (SED) of production. The different policies and effects of the variation of feed composition are studied for the separation of the mixture dichloromethane-acetone. The lowest SED is obtained by SBD with feeding at a variable location of the column (SBD3). However, feeding at a fixed location (SBD2) is much simpler to realise and only slightly inferior. Further reduction of SED is reached by using two SBD2 or one SBD2 and one BD step with different reflux ratios. The separation of the mixture n-hexane-n-heptane-n-octane is also studied by SBD1 and SBD2 policies with both direct and indirect sequences. The energy demand of SBD2 in indirect sequence is lower than that of the direct sequence by 25%. By applying SBD2, SED was reduced by 38% and 39% for binary and ternary mixtures, respectively, compared to BD.

  • Acidophilic biodesulphurization of calcined pet coke and coal samples in
           iron and iron-free leaching media
    • Authors: Srabani Mishra, Sandeep Panda, Nilotpala Pradhan, SK Biswal, D Satapathy
      Abstract: Energy & Environment, Ahead of Print.
      Mineralogically distinct coal samples respond differently to microbial attack. In the present study, a mixed meso-acidophilic bacterial consortium predominantly comprising of Acidithiobacillus ferrooxidans strain was investigated for its biodesulphurization abilities for three distinct sulphur bearing samples (Goa CPC, Rajasthan Lignite, Assam Coal) of Indian origin in iron (9K+) and iron-free (9K−) media. A media devoid of Fe (II) iron was more effective for sulphur removal with maximum desulphurization of 45.19% for Assam coal followed by 36.8% for Rajasthan Lignite and 23.38% for CPC respectively. The proximate analysis, FTIR patterns and XRD analysis of the samples provided better insights into understanding the mineralogical and compositional changes in the coal matrix. Owing to the higher efficiency, Assam coal was additionally subjected to further optimization studies and characterization of the treated coal through TGA. The study indicated that the gross calorific values for all the samples increased following microbial treatment in 9K− media thereby providing a scope for further scale-up studies.

  • Mitigation pathways impact of climate change and improving sustainable
           development: The roles of natural resources, income, and CO2 emission
    • Authors: Syed Tauseef Hassan, Enjun Xia, Chien-Chiang Lee
      Abstract: Energy & Environment, Ahead of Print.
      AbstractClimate change is an obstacle in the path of sustainable economic development. One of the key findings in the economics literature is that the use of natural resources contributes to real income per capita. However, its environmental consequences should not be ignored. This paper examines the nexus among CO2 emission, real income, and natural resources, by incorporating urbanization, and trade in Pakistan from 1971 to 2017. The Auto-Regressive Distributive Lag (ARDL) and Vector Error Correction (VECM) models are used for analyzing time-series data. The empirical findings infer that the use of natural resources accelerates the rate of CO2 emission in Pakistan which worsens environmental quality. In addition, the Environmental Kuznets Curve (EKC) is confirmed in the presence of natural resource use. Besides, urbanization improves environmental quality through mitigating the level of CO2 emission. Moreover, the feedback hypothesis is found between the use of natural resources and CO2 emission. Additionally, bidirectional causality is found between urbanization and the use of natural resources. Overall, this study supports formulating new policies to overcome environmental degradation through energy-saving technologies.

  • Effect of calcination temperature on properties of waste alkaline
           battery-based catalysts for deep oxidation of toluene and o-xylene
    • Authors: Young-Kwon Park, Min Ki Kim, Sang Chul Jung, Wang Geun Shim, Seong Ho Jang, Sang Chai Kim
      Abstract: Energy & Environment, Ahead of Print.
      To evaluate waste alkaline battery (WB) as a catalyst for deep oxidation of toluene and o-xylene, we investigated how calcination temperature influenced the catalytic activity of WB-based catalyst for catalyst preparation. Physicochemical properties of WB-based catalysts were characterized by BET (Brunauer Emmett Teller) analysis, XRD (X-ray diffraction), SEM/EDX (scanning electron microscope/energy dispersive X-ray), TGA/DTA (thermo gravimetric analysis/differential thermal analysis), and H2-TPR (hydrogen temperature programmed reduction). Major elements of WB-based catalysts were carbon, manganese, zinc, and iron. The catalytic activity of WB-based catalyst was significantly influenced by calcination temperatures ranging from 300 °C–600°C. An increase calcination temperature resulted in a significant decrease in the BET surface area and concentrations of surface carbon and chlorine of the WB-based catalyst, while levels of other components increased. The average pore diameter of the WB-based catalyst calcined at 400 °C (WB (400) catalyst) was the smallest. The concentrations of manganese and iron in WB (400) catalyst were the highest, while those of manganese and iron in the WB-based catalyst calcined at 300 °C (WB (300) catalyst) were the lowest. Therefore, a good performance of WB (400) catalyst was likely due to its higher concentrations of manganese and iron and smaller pore size. When GHSV (gas hourly space velocity) was 40,000 h−1, toluene and o-xylene were completely oxidized on WB (400) catalyst at 430 °C and 440 °C, respectively.

           based power generation in Malaysia
    • Authors: ABM Abdul Malek, M Hasanuzzaman, Nasrudin A Rahim, Yusuf A Al–Turki
      Abstract: Energy & Environment, Ahead of Print.
      Biomass gasification based power plants can play an important role in power sector in Malaysia with her abundant agricultural and forest resources. In this research energy and economic feasibility, and environmental impact of biomass gasification power plant has been analyzed and assessed for sustainable power generation in Malaysia, the plant being a clean development mechanism supported project. Gasification based power generation with a dual fuel internal combustion engine is found more biomass combustion power plant. But, the annual fuel cost is significantly higher with gasification plant claiming MYR 10 million/y for a generation of 67,500 MWh. The net present value, internal rate of return, and PBP for a 10-MW gasification based dual fuel internal combustion engine power plant without loan financing using empty fruit bunch pellet as biomass; with CER issued at USD16/tCO2; and without loan financing provides net present value, internal rate of return, and PBP of MYR 19.68 million, 11.90%, and 6.05 y, respectively. With a loan financing at 3% per year with CER still be effective the net present value, internal rate of return, and PBP is estimated to be MYR 7.03 million, 3.97%, and 11.78 y, respectively. However, if a 60:40 debt equity is applied then the project net present value, internal rate of return, and payback period seen to improve slightly. The net present value attains a positive value of MYR 3.6 million. Internal rate of return and PBP values are found to be 7.08% and 8.27 y, respectively. The emission reduction achieved with the plant is 17,863 t CO2/y, 206 t SO2/y, 90 t NOx/y, and 10.37 t CO/y, respectively. Energy efficiency and tariff policy have been found to have highest impact on economic profitability of gasification based power generation units.

  • Selection of solar collector network design for industrial applications
           subject to economic and operation criteria
    • Authors: Juan R Lizárraga-Morazán, Guillermo Martínez-Rodríguez, Amanda L Fuentes-Silva, Martín Picón-Núñez
      Abstract: Energy & Environment, Ahead of Print.
      The aim of this paper is to present a design approach for the selection of the most cost-effective solar thermal plant composed of flat plate solar collectors for a given process. The approach seeks to provide the designer with the necessary elements for decision making, namely minimum total operating costs, minimum required plot area for installation, maximum daily operating time and determination of payback time. The optimisation methodology search uses a cost equation for flat plate solar collectors along with a thermal model linked in a MatLab and General Algebraic Modeling System (GAMS) platform. In stand-alone collector design, tube diameter, tube length and collector width are the variables that have a major impact on the cost; in the case of solar collector fields, the number of collectors in series is the variable with the strongest impact. It is shown that the optimised networks fulfil the thermal duty within the limitation of land area. The designs are carried out for the conditions that guarantee operation throughout the year and exhibit saving of up to 50% and payback times lower than six years. The approach is demonstrated using a case study.

  • The rise of community choice aggregation and its implications for
           California’s energy transition: A preliminary assessment
    • Authors: Sean F Kennedy, Bailey Rosen
      Abstract: Energy & Environment, Ahead of Print.
      Community choice aggregation—an emerging electricity supply model allowing residents and businesses to purchase electricity from local governments instead of utilities—is projected to account for 60% of Californian customers currently served by investor-owned utilities by 2020.Community choice aggregation advocates claim that the model is an effective means of meeting California’s renewable energy policy objectives in a way that is more democratic and socially just than the prevailing utility-based model of electricity governance. We interrogate these claims through a focus on three issues: community choice aggregation governance and access to capital, electricity procurement, and customer rates and retention. We find that community choice aggregators have been able to address concerns regarding access to capital while balancing competing objectives around renewable energy and affordability. However, local benefits—particularly in terms of local economic development driven by the expansion of distributed generation—are yet to be fully realized. In addition, ongoing policy uncertainty regarding cost allocation between utility and community choice aggregation customers may limit the ability of community choice aggregators to offer competitive rates, which may threaten the model’s long-term viability. We conclude by arguing that meeting California’s future renewable energy requires a reconfiguration of the regulatory framework that leverages the respective strengths of both community choice aggregators and investor-owned utilities in the context of the state’s energy transition.

  • Heterogeneous impact of CO2 emissions on renewable energy technology
           innovation between oil importers and exporters
    • Authors: Bai Liu, Yutian Liu, Ailian Zhang
      Abstract: Energy & Environment, Ahead of Print.
      With the depletion of fossil energy and the rise of global temperature, it is urgent to use renewable energy to solve environmental problems. By studying the heterogeneous relationship between CO2 emissions and renewable energy technology innovation in different countries, we can find out the gap and something helpful to energy development. In the empirical test, we use the negative binomial regression model with fixed effects to study the impact of CO2 emissions on renewable energy technology innovation from 1997 to 2016. The research shows that impact is positive in oil-importing countries, but this relationship is not established in oil-exporting countries. In both oil importers and oil exporters, CO2 emissions have a positive effect on the solar energy technological innovation, however, the influence on the technology innovation of solar energy in oil exporters is more significant than that of renewable energy. Whether for oil importers or oil exporters, it can be more reasonable and effective to develop renewable energy by clarifying the impact of CO2 emissions on domestic renewable energy technology innovation.

  • Anaerobic digestion: Technology for biogas production as a source of
           renewable energy—A review
    • Authors: KeChrist Obileke, Nwabunwanne Nwokolo, Golden Makaka, Patrick Mukumba, Helen Onyeaka
      Abstract: Energy & Environment, Ahead of Print.
      The authors reviewed the future prospects and previous studies on anaerobic digestion technology for biogas production and highlight the solutions to problems relating to construction and maintenance of biogas digesters, which can now be accessed in a single paper. It is the aim of the review to provide insight into the use, process and application of anaerobic digestion as an appropriate technology for biogas production from peer reviewed literature. Recent studies have shown that the microbial communities and metabolic pathways involves in anaerobic digestion are influenced by temperature. Their metabolic activities increase significantly with increase in temperature. Therefore, the findings of the review reveal that temperature is a major parameter for biogas production due to its influence on metabolic activities involved in anaerobic digestion. Hence, there is the need for insulation as well as external heating to maintain temperature stability and to avoid temperature fluctuations. More also, the anaerobic digestion technology for production of biogas is a viable option that can supplement as well as reduce the usage of non-renewable energy sources such as fossil fuel. The detailed information addressed in this study would increase biogas energy mix as well as mitigating climate change. Therefore, the study recommends the use of biogas as a clean energy for the purpose of power generation, cooking and heating.

  • Analytical assessment of a concentrated solar sub-critical thermal power
           plant using low temperature heat transfer fluid
    • Authors: Umish Srivastva, K Ravi Kumar, RK Malhotra, SC Kaushik
      Abstract: Energy & Environment, Ahead of Print.
      The paper presents energy–exergy–economic–environment–ethics analysis of a concentrated solar thermal power plant. Design basis of a concentrated solar power for 24 h operation on parabolic trough collector technology in best suited direct normal irradiation location and least capital cost analysis has been presented. An unconventional approach of reducing the capital cost is analyzed by intentionally designing the power plant for sub-critical conditions using a low-cost mineral oil with permissible operating temperature of 320°C in place of the conventional synthetic solar grade oil of 400°C. Using low pressure and temperature steam in the plant, it has been shown that while there is a reduction of 0.1% in energetic efficiency, there is a gain of 0.28% in the exergetic efficiency of the solar power plant conditions, gross thermal efficiency decreases by 1.18% and the net thermal efficiency decreases by 2.91%. However, the energetic and exergetic utilization factor for heat transfer fluid is increased by 0.84 and 5.58%, respectively. By suitably adjusting the solar field configuration and inlet oil temperature, energy savings to the tune of 45% is possible apart from 2.5 times of cost saving. An attempt has been made to quantifiably assess the ethics of switching to renewable electricity through shared responsibility as a novelty in the study. The payback period for the investment has also been shown to reduce from 20 years to 5 years assuming that the carbon price increases, concentrated solar power cost comes down by 25%, and cost at which electricity can be sold increases to US $0.14 (Rs. 10) per unit.

  • Analysis on new types of electric power businesses using a morphological
           box
    • Authors: Chankook Park, Daeyoun Lee
      Abstract: Energy & Environment, Ahead of Print.
      This study analyzed new electricity business cases with an aim to categorize them systematically based on theoretical grounds. The previous research studies on new businesses in the electric power sector lack the perspicuous theoretical basis for the criteria for classification and fail to examine a wide range of cases or the further possibility of new businesses development. Complementing the shortcomings, we adopted the morphological box for categorization to compare several business cases and draw the main types of businesses. It has revealed that utilities as well as residential, commercial, industrial customers also act as the main customers for the distributed resources while cooperation among different industries is growing rapidly, and local governments are actively involved in the business as the main providers. Also, cases related to consumer service innovation including consumer choice expansion and customized services are often seen. Furthermore, free services have emerged in the sector. This study has significance in that it successfully reassessed the theoretical arguments on business models and rearranged the parameters of the morphological box suitable for analyzing more than 100 business cases.

  • Spatial and temporal pattern evolution and influencing factors of
           energy–environmental efficiency: A case study of Yangtze River urban
           agglomeration in China
    • Authors: Zhaoqiang Zhong, Benhong Peng, Ehsan Elahi
      Abstract: Energy & Environment, Ahead of Print.
      Improving energy–environmental efficiency is prerequisite for sustainable development. In order to explore ways to improve energy–environmental efficiency, this paper uses the undesired output slack-based model to measure the energy–environmental efficiency of the Yangtze River urban agglomeration based on the input and output index data from 2008 to 2017, and its spatial and temporal pattern evolution is analyzed by using kernel density estimation, Gini coefficient, and coefficient of variation. Moreover, the Tobit regression model is used to analyze the influencing factors of the energy–environmental efficiency of the Yangtze River urban agglomeration. The results indicate that the energy–environmental efficiency of each city is increased continuously, and the regional differences are gradually narrowed. The spatial pattern is changed from polar nucleus type to valley type, and finally the distribution characteristics of “overall high” are formed. Overall, the energy–environmental efficiency presents a spatial layout of “high in the east and low in the west.” The regression results show that the level of economic development and energy–environmental efficiency are “U-type” associated characteristics, and government regulation and population density have significant positive effects on it. Industrial structure and technological progress have negative effects on it, and the effect of opening degree is not significant.

  • Comparative study of air quality indices in the European Union towards
           adopting a common air quality index
    • Authors: Zissis Karavas, Vayos Karayannis, Konstantinos Moustakas
      Abstract: Energy & Environment, Ahead of Print.
      This study aims to compare air quality indices applied in European Union countries towards adopting a common air quality index. The urban European cities Rome, Madrid, Paris, London, Berlin, Warsaw, Stockholm, and Oslo were selected. Using the EEA AirBase air quality database, time series data for the major atmospheric pollutants (CO, NO2, SO2, O3, PM10, and PM2.5) were recovered for each city, for most recent years available. Daily averages, maximum hourly values and maximum 8-h averages were calculated for each pollutant. The air quality indices selected were BelAQI, DAQx, DAQI, AtmoIndex, AQIH, and CAQI. The daily value of each air quality indices and the corresponding dominant atmospheric pollutant were determined for each city. A two-stage normalization procedure was applied on air quality indices in a 0–1 range, to allow their direct comparison without altering their structure. All air quality indices exhibited air quality rates over 64% for all cities, thus below the European Union air quality standard. The dominant pollutant was NO2 for both BelAQI and DAQx; O3 for both DAQI and AQIH (with an exception for Warsaw where SO2 was the dominant pollutant). For CAQI, NO2 prevails in Berlin, London, Warsaw, Stockholm, and Oslo, while O3 prevails in Rome, Madrid, and Paris. The dominant pollutant for AtmoIndex was NO2 in Berlin, Warsaw, and Stockholm; O3 in Madrid, Paris, London, and Oslo; PM10 in Rome. A very strong positive statistical correlation (p

  • Catalytic reduction of nitrate in reverse osmosis concentrate by using
           Pd-Cu/activated carbon felt
    • Authors: Carolina Andrea Bahamondes Fuentes, Yuhoon Hwang
      Abstract: Energy & Environment, Ahead of Print.
      The reverse osmosis concentrate generated during the water reuse process contains a high concentration of nitrate but a low amount of biodegradable organic carbon for heterotrophic denitrification. Catalytic reduction of nitrates using Pd-Cu is one of the most promising technologies to achieve complete removal of nitrate; however, the effect of a range of experimental factors on the nitrate removal rate and N2 selectivity is still an ongoing concern. Two kinds of supporting materials, alumina and activated carbon felt, were used to immobilize the Pd-Cu catalyst. The alumina-based catalyst was used to establish reference conditions for further experiments, and the effect of pH control was evaluated for both supporting materials. It was observed that pH has a direct influence on the nitrate reduction rate as well as the N2 selectivity. Nitrate reduction efficiency was low at acidic conditions while the highest N2 selectivity was obtained at the acidic conditions. The optimal pH condition for Pd-Cu/activated carbon felt was determined as pH 4, showing the highest total nitrogen removal as N2 gas. Finally, the feasibility of catalytic nitrate reduction for reverse osmosis concentrate was evaluated by investigating the effects of organic and inorganic components commonly present in reverse osmosis concentrate. The organic and inorganic components did not show a significant inhibitory effect on catalytic nitrate reduction, while a high concentration of salt significantly decreased the nitrate reduction rate as well as the N2 selectivity. The filter type morphology of the Pd-Cu/activated carbon felt would be beneficial for field application compared to the conventional catalyst with powder form.

  • Anaerobic degradation of palm oil mill effluent with aluminum bauxite
           residue for methane production
    • Authors: Anwar Ahmad, Salam S AlDawey, SS Reddy
      Abstract: Energy & Environment, Ahead of Print.
      Experimental study of the anaerobic digestion of palm oil mill effluent (POME) was carried out in an anaerobic upflow sludge blanket reactor (UASBR) with bauxite residue. The production rate of methane 114 L/gCOD/d and CH4 concentration was 205 L gCOD/d at 8.5 g/L of bauxite residue in UASBR. The results showed that the highest methane yield was 37.5 L gCODadded/h; CO2 reduction 1.5 L gCODadded and chemical oxygen demand (COD) removal reached 98.3% at 8.5 g/L of bauxite residue, respectively. The results the best by the modified kinetic model and Umax was 100 mg/L. The kinetic of methane production was also studied. The methane yield coefficient, YM, was 0.69 L CH4/gCODremoved. Anaerobic digestion of acetate was the dominant soluble metabolites in development and specific methanogenic activity results showed that high observed between stoichiometric and experimental higher methane production.

  • Comparative study on the economic feasibility of nanogrid and microgrid
           electrification: The case of Jeju Island, South Korea
    • Authors: Jinwoo Bae, Soojung Lee, Heetae Kim
      Abstract: Energy & Environment, Ahead of Print.
      Due to heavy fuel dependence, the “renewable energy system” idea is an important issue in South Korea. The government of South Korea is endeavoring to convert its energy infrastructure into renewable energy generation. As such, numerous studies have evaluated the economic feasibility of various renewable energy sources in South Korea. This study differs from those studies as it is focused on a smaller scale in terms of self-supporting nanogrid and microgrid energy. The purpose of this study is to determine which type of grid is more economical. To conduct a comparative study on the economic feasibility of nanogrids and microgrids, three substations on Jeju Island were randomly selected. We then suggested two scenarios. The first scenario is , which changes each substation into a nanogrid, and the second is , which connects the three nanogrids to share electricity. This study identifies the optimal combination of hybrid energy resources using HOMER (hybrid optimization model for electric renewables) software to change the substations into an self-supporting energy nanogrid or microgrid. According to the net present cost and cost of energy results for each scenario through HOMER simulations, the scenario is more economical than the scenario. However, this study also shows that microgrids can be the better option, depending on the distance between nanogrids. Finally, implications and limitations are discussed in the last section of this paper.

  • Can pollution charges reform promote industrial SO2 emissions
           reduction'—Evidence from 189 China’s cities
    • Authors: Da Gao, Yi Li, Qiuyue Yang
      Abstract: Energy & Environment, Ahead of Print.
      This paper evaluates the real effects of pollution charges reform on [math] emissions at the city level. Using the establishment of Comprehensive Work Plan for Energy Conservation and Emission Reduction (The Plan) in China as a quasi-natural experiment, our difference-in-differences estimation shows that: (1) increasing pollution charges has a significant and positive effect on controlling industrial waste [math], and this relationship is robust to different specifications and alternative measures; (2) [math] emissions can be reduced to achieve reduction targets by forcing companies to strengthen the degree of process production controls and end-of-pipe treatment; (3) eastern and western cities have a better pollution control effect than the other regions, and large cities have better emission reduction effects than smaller cities. Overall, this paper sorts out the evolution of China’s pollution charge policy, and reveals the mechanisms behind the real effects of pollution charges reform on [math] emissions, thus providing timely implications for policymakers concerned with environmental protection.
