Understanding the current energy landscape requires assessing past achievements, leveraging resources, embracing technological advancements, and implementing effective policies. A thorough analysis is vital to identify gaps in achieving our Nationally Determined Contributions, ultimately facilitating net-zero goals. The urgency to mitigate emissions, heightened by climate-induced events and the need for renewable energy integration, calls for a reconsideration of net-zero timelines. Delayed action poses significant risks to ecosystems and economies globally. This paper explores how different pathways to net-zero emissions for power sector by 2050 &amp; 2070 target years impact the future electricity mix, costs, generation profiles, and emission trajectories. We employ the energyRt optimization model, a bottom-up framework capturing regional, seasonal, and diurnal variations of renewable energy sources for thirty years, from 2020 to 2050. Preliminary analysis suggests current renewable resource estimations might not be sufficient for a 2050 net-zero goal. To meet the projected 6273 TWh demand by 2050, installed capacity would range from 2042 GW to 3100 GW. The base case emission trajectory reaches 2.4 GtCO₂/year in 2050 with a grid emission factor of 0.369 tCO₂/MWh. Achieving net-zero emissions by 2070 with CCS requires 33.37 % less investment than without CCS. The findings emerging from this analysis provide valuable insights into the power sector decarbonization pathways available to India in its pursuit of net-zero emissions.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101637"},"PeriodicalIF":4.4,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs the Open-Source Energy Modeling System (OSeMOSYS) model to analyze low-carbon transition pathways for Mauritius, which are aligned with its nationally determined contribution (NDC) objectives to increase renewable energy to 60 % and phase out coal by 2030. The study applied key performance indicators to assess this pathway against energy self-sufficiency, economic, environmental and social criteria. The study showed that renewable energy sources, namely, solar, biomass, wind and waste-to-energy, can be game-changers for the island. The optimal transition pathway would achieve a renewable target of 76.8 % and reduce CO₂ emissions by more than 67 % across the modeling period at an estimated cost of 1.94 billion USD by 2040. Finally, the study evaluated the implications of Mauritius' clean transition in terms of its effects on green jobs as well as whether there is sufficient infrastructure, administrative and financial capacity and energy pricing policies to support the optimal pathway. The study concludes that the experience modeling a low-carbon transition pathway for Mauritius could also offer useful lessons for other SIDS contemplating similar transitions.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101638"},"PeriodicalIF":4.4,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve net-zero emissions by 2070 and meet 50 % of the total installed capacity from non-fossil fuel-based energy resources by 2030, it plans to build 500 gigawatt (GW) of non-fossil energy capacity comprising mainly 280 GW of solar, 140 GW of wind, and 61 GW of large hydropower projects. Multiple technical and financial impediments are impacting the scale and speed needed to achieve these targets. But that is not all; the planning and execution of such large projects relies heavily on the availability of, and access to, land. The presence of contestations, conflicts and social uprisings from some of India's most dispossessed, marginalised groups, afflicting several planned and ongoing large renewable energy projects highlights the socially complex nature of these developments. This paper is an effort to unpack this complexity by applying the principles of consultation and consent. Specifically, the paper asks three questions: first, what is the nature of engagement and consultation posited in the policy and regulatory landscape currently driving India's renewable energy development process? Second, how does it compare with key international norms and commitments? Third, what recommendations can be made to strengthen consultation and consent principles in India's renewable energy policy and practice? Addressing these questions advances our collective understanding of how renewable energy ambitions interface with India's plans for a people-centric, fair, and just transition.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101613"},"PeriodicalIF":4.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the lack of comprehensive studies on monetizing and accounting for the overall direct and indirect cost benefits of biogas plants often hinders benefit communication to people and the preparation of appropriate policy measures for net zero energy transition in many developing countries. To address these issues, this study conducted a nationwide household survey comprising 1392 primary samples in Nepal, using a benefit-accounting framework based on different biogas sizes in three ecological belts (mountains, hills, and Terai). The results revealed that an average household biogas plant replaces 4.5 tons of biomass annually. Direct annual economic savings by a one cubic meter biogas plant in the Terai region were found to be NRs 9000 (USD 69.23). In contrast, in the hilly and mountainous regions, the benefits increased by NRs 2250 and NRs 4500 respectively. Annual displacement of fuel wood by the total household biogas plants installed in Nepal accounted for 1.8 million tons and saved 2.8 million tons equivalent CO₂ emission. Besides the direct benefits, many indirect and social benefits linked to crop productivity, timesaving for economic activities, improved health, and the environment were investigated. Accounting for integral benefits, biogas plants had significant (35 to 43 %) additional benefit contributions over direct savings, which are often neglected in accounting frameworks. Government subsidies have improved the feasibility of biogas plants. Outcomes beyond these accounting values only, this study provides several policy implications for the wider-scale promotion of household biogas in developing countries for meeting net zero energy transition goals.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101634"},"PeriodicalIF":4.4,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143102558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modellers and analysts have used these tools to support international organizations and policymakers in crafting and making decisions about energy policy. Open-source frameworks have been instrumental in this progress, enhancing stakeholder engagement, transparency, and public acceptance. Among these, the Open-Source Energy Modelling System (OSeMOSYS) stands out as a key example, widely applied in energy transition and planning studies. As the body of OSeMOSYS literature rapidly expands, it is essential to track research advancements to guide both current and future modellers. This paper presents a systematic literature review, exploring the applications, developments, and research trends related to OSeMOSYS over the last 10 years. The findings highlight a significant growth in OSeMOSYS-based research, with an annual increase of approximately 28 %, and most applications occurring in Africa and Latin America, though largely conducted by European institutions. Six key application areas were identified, such as capacity expansion planning in the power sector, transport sector planning, and sector coupling opportunities. Nine categories of complementary methods commonly integrated with OSeMOSYS were also categorized, including power sector performance, stakeholder engagement, and geospatial assessments. A thorough review of code enhancements demonstrates the framework's adaptability to various fields, such as flexibility assessment, hydropower systems, and storage modelling. Furthermore, seven key future research directions were identified: operational feasibility, uncertainty evaluation, temporal and spatial resolutions, technological detail, storage modelling, and macroeconomic impacts.

However, traditional systems do not allow for precise control over the temperature of the saltwater. This study introduces a novel approach by integrating a spiral type solar heater for salt water heating, which elevates the saltwater temperature to higher levels. To implement the proposed set up, the integration of a spiral-type solar heater, cotton-based materials, and a perforated pipe for delivering heated saltwater should be adopted, along with intermittent water pump operation to optimize heat absorption and evaporation efficiency. This enhancement enables more efficient condensation, which is achieved using a long triangular prism condensation unit. From the obtained results, it was revealed that the proposed mini solar still system can be modified by using cotton base materials and dripping salt water from a perforated pipe can enhance the distilled water by 138.46 %.
