The spatial distribution of the Napier grass dry matter yield (DMY) is among these important data. Unlike agricultural residues, the spatial distribution of the DMY cannot be obtained through surveys or statistical data. In this study, a methodology for locating biogas power plants utilizing Napier grass as a feedstock is proposed. A geographic information system and analytic hierarchy process are used to evaluate land suitability for biogas power plants based on environmental and socioeconomic criteria. The spatial distribution of the DMY is integrated with the land suitability map to locate suitable sites for biogas power plants. The proposed approach is applied to southern Thailand because the region lacks self-sufficient power generation. The results reveal that, five biogas power plants that utilize Napier grass from abandoned areas can be established with a total contracted capacity of 420 MW. Based on this analysis, introducing Napier grass-based biogas power plants could significantly help reduce the dependency on imported electricity. Stakeholders are recommended to treat this study as a tool to be utilized before implementing new dedicated energy crops.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667095X21000118/pdfft?md5=0b1a0ec73be89f5087df04f7cd599fe5&pid=1-s2.0-S2667095X21000118-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75592915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these systems have a challenging cost to revenue ratio, hindering their implementation. Combining residential loads with an anchor load, a relatively large non-domestic user, can help to improve mini-grid economics. Using measured electricity demand data from India and energy modelling, we assess the cost and emissions advantages of integrating health clinics as anchor loads within domestic solar mini-grids. For comparison, we also assess the ability of the national grid to meet our demand scenarios using monitored grid data. We apply a scenario-based approach, using separate domestic and anchor load demand profiles, and both in combination; we test meeting two levels of energy demand, 95% and 100%; and compare systems using PV and batteries, diesel, and hybrid generation. We find that the national grid has poor availability, at just over 50% at the most comparable monitoring site; and that it would meet a lower fraction of energy demand for our anchor load scenarios than the domestic only ones. For the off-grid systems, we find substantial cost and emissions reductions with anchor loads relative to demand scenarios without anchor loads. At 95% of demand met, we find PV and battery systems are 14-22% cheaper than diesel-only systems, with 10 times lower carbon intensity. Our findings illustrate the role off-grid systems can play in the provision of reliable low-carbon electricity and highlight the advantages of incorporating anchor loads like health centres into such systems.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rset.2021.100003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81363430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, green hydrogen produced by offshore wind emerges as a promising solution to remove barriers towards a carbon-free economy in Europe and beyond. Motivated by the recent developments in Denmark with the decision to construct the world's first artificial Offshore Energy Hub, this paper investigates how the lowest cost for green hydrogen can be achieved. A model proposing an integrated design of the hydrogen and offshore electric power infrastructure, determining the levelised costs of both hydrogen and electricity, is proposed. The economic feasibility of hydrogen production from Offshore Wind Power Hubs is evaluated considering the combination of different electrolyser placements, technologies and modes of operations. The results show that costs down to 2.4 €/kg can be achieved for green hydrogen production offshore, competitive with the hydrogen costs currently produced by natural gas. Moreover, a reduction of up to 13% of the cost of wind electricity is registered when an electrolyser is installed offshore shaving the peak loads.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.rset.2021.100005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76811926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper takes India as a case study to examine a nexus-informed approach to policy making for redressing the EWF security (EWF-s) challenges. First, a Leontief demand-driven EWF-extended Input-Output model is developed. The Leontief's production functions (representing endogenous, fixed technical coefficients) of the developed model are then further modified using flexible functions to capture EWF-related technological and policy interventions. The resulting changes in the model (to include divergent input substitution possibilities) allow evaluation of policy scenarios with nexus or non-nexus considerations towards EWF-s. These scenarios assess outcomes across diverse domains (physical, social, economic, environmental) in short, medium, and long-run over the period 2015-2047. The results show that not only does the EWF nexus-oriented scenario produce major co-benefits demonstrated in terms of the most significant long-term improvement in EWF outcomes but that it also achieves considerably superior economic, social, and environmental outcomes. Synergies and trade-offs across various policy scenarios are also discussed. The insights obtained from the application of this approach, especially cross-sectorial (EWF), cross-domain, and temporal can provide promising takeaways for policymakers to adopt a robust and sustainable strategy for tackling the EWF-s challenges.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667095X2100012X/pdfft?md5=fc50bb3e6116f8935870709d0690d481&pid=1-s2.0-S2667095X2100012X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72930022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimate optimal battery storage and power generating capacities and their hourly operation in a 2040 Indian wholesale electricity market using an open-source power sector model. We find that battery storage increases the optimal solar PV shares from ∼40-50 % (without batteries) to ∼65 % (90%) in our central (optimistic) battery cost scenarios, while they hardly increase in our pessimistic battery cost scenario.
