DC microgrids necessitate specialized equipment and control systems to integrate renewable energy sources, energy storage systems, and loads. This integration is particularly challenging in remote locations with limited expertise and maintenance support. The proposed microgrid operates passively, meaning it does not use additional devices or communication between power conditioners to manage the grid's voltage. This alternative approach employs conventional equipment from Solar Home Systems (SHS) using a passive open structure because, despite the global use of SHS in electrification projects for their simplicity and cost-effectiveness, there are limitations in capacity, generally restricting energy use to only one home. A more reliable system with enhanced power delivery capacity can be achieved by interconnecting SHS to form a microgrid. This paper discusses the development of a 24 V DC microgrid using commercial off-the-shelf components, contrasting with the sophisticated equipment typically required. The laboratory testing and the implementation in an Amazonian community are described. The laboratory facility has three SHSs and three independent loads used to evaluate the concept and design, demonstrating operating principles and system capabilities, such as load sharing under typical operating conditions and operation under contingencies. The community DC microgrid is then implemented with five interconnected SHSs, one without batteries, in a remote Amazonian community to run productive end-uses and domestic loads, which were monitored, and the practical results evaluated. The laboratory and community systems demonstrated improved reliability over an individual SHS. When failures occurred within the system, the other generation nodes continued to supply power to the loads. It was also found that 55 % of the total consumption (1963 kWh) was serviced from the battery and that generation curtailment often occurred during the day as most loads did not coincide with the peak generation time, indicating a significant potential for optimizing the energy usage from the load side. At the main nodes, the voltage range is between 0.96 and 1.21 p.u. During the day, the voltage is primarily determined by charging modes, with median values between 1.08 and 1.14 p.u. In contrast, at night or on cloudy days, the battery's voltages partially or wholly establish it, with median values between 0.97 and 0.99 p.u. The four community households surveyed had overwhelming positive views of the microgrid. These outcomes show the potential of this DC microgrid design to support the off-grid energy transition.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"86 ","pages":"Article 101690"},"PeriodicalIF":4.4,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143609223","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}

In this paper, we investigate the role of retrofitting India’s coal plants for carbon capture and storage (CCS) and biomass co-firing in developing the net-zero power system.

The reliance on hydroelectric power, exacerbated by climate-induced droughts, has led to severe energy shortages and up to 21-hour daily load-shedding. This research addresses the dual challenge of energy poverty and unsustainable edible non-timber forest product (ENTFP) practices in rural Zambia. Despite the potential of solar photovoltaic (PV) systems to mitigate energy poverty and enhance livelihoods, adoption remains limited. Simultaneously, wild foods - such as wild honey, fruits, traditional beer, and leafy vegetables - are not only consumed in rural areas, but also crucial income sources. However, they face unsustainable harvesting practices, threatening rural food security, biodiversity and long-term viability. This study investigated the relationship between ENTFP - derived income and solar PV adoption. It explored financing mechanisms tied to ENTFPs, evaluated their benefits and limitations, and examined their environmental and social impacts. The study utilized the Rural Development Stakeholder Hybrid Adoption Model (RUDSHAM), integrating theories such as Technology Acceptance Model, Diffusion of Innovations, and Social Learning Theory. Data were collected through 40 in-depth interviews, 7 focus group discussions, and stakeholder consultations across three rural districts in Zambia. NVIVO 14 was employed for thematic coding and analysis, ensuring representation of diverse stakeholder perspectives. Income from ENTFPs supports solar PV adoption by providing critical financial resources. Some ENTFPs like wild honey sometimes yield even higher revenues than agriculture, enabling energy investments. However, commercialization poses food security and sustainability risks, such as habitat degradation and resource depletion. Social impacts include empowerment through improved energy access but also risks of community conflict over resource competition. Solar PV systems contribute to reduced deforestation and CO<sub>2</sub> emissions, aligning with environmental conservation goals, but require balanced management of ENTFP practices to ensure ecological health. The study recommends the need for robust policies promoting sustainable ENTFP harvesting and solar PV integration. Community-driven strategies, coupled with educational initiatives on sustainable practices, can promote resilience and energy equity. Expanding alternative income sources can mitigate overdependence on ENTFPs, ensuring balanced economic, social, and environmental outcomes.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"85 ","pages":"Article 101694"},"PeriodicalIF":4.4,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593448","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}

While the pathways connecting energy access to the four dimensions of food security (availability, access, utilisation, and stability) are well established in the literature, only a few studies empirically provide evidence of the relationship between energy access and food security, particularly in the humanitarian context. Drawing from 926 household-level observations collected via in-person interviews in settlements in Uganda, Malawi, and Zambia, this study contributes new insights on the influence of electricity access on food security in protracted refugee situations. Within the sampled population, 65 % of households experience severe food insecurity while a substantial 76 % majority lacks access to a reliable electricity service. Through a logistic regression analysis, we detect a mitigating effect of electricity access on severe food insecurity, although weakly significant, while controlling for income, gender of the household head, household size, and settlement dummies. The odds of experiencing severe food insecurity are reduced by a factor of 0.7 for households with access to electricity compared to those without access. However, they increase for households located in the most economically disadvantaged settlement. The study highlights the importance of policies that support the right to work and empower female-headed households, as income-generating activities play a mitigating role; in turn, households headed by women are about 1.7 times more likely to experience severe food insecurity compared to those headed by men.
