To address this challenge, a solar freezing system was developed for rural areas with unreliable electricity. This system allows Mongolians to store meat in frozen storage during the fall, when prices are low, and sell it in the spring when prices are higher. Although rural Mongolia generally has a stable power supply, frequent outages necessitate a freezing system capable of operating under such conditions. The proposed solar freezing system utilizes solar power and the cold storage effect to maintain meat temperatures below −18 °C, a significant improvement over existing solar-powered systems, which can only maintain temperatures above 0 °C. Mongolia's dry, highland climate makes it particularly well-suited for such applications. A meat storage unit with improved insulation was tested to minimize reliance on regular grid power. Additionally, a simulator was developed to analyze system performance outside the winter period when the experiment was conducted. The results confirmed that the solar freezing system could operate continuously during winter with minimal reliance on grid power, provided it was turned off at night. The cold storage effect of the meat, combined with enhanced insulation, effectively prevented temperature increases. The solar freezing system reduced initial investment and maintenance costs by eliminating the need for batteries. This system will be paid back in 8.2 years using the Net Present Value (NPV) analysis, assuming no interest is charged. Thus, a freezing system for long-term meat storage during the Mongolian winter was successfully developed. Furthermore, simulation results indicated that meat storage using low-cost late-night electricity during summer nights in Mongolia is also feasible.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101710"},"PeriodicalIF":4.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143783040","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}

This study provides the first comprehensive assessment of the total cost of ownership (TCO) for five types of commercial vehicle models in various provinces of China under three fuel options: diesel, electric, and hydrogen fuel cell. The study systematically quantifies the cost differences and applicability of different fuel types and vehicle models at the provincial level, as well as the nuanced impact of temperature variations. The results indicate that electric trucks with a capacity of 4.5-ton (4.5 t) and 49-ton (49 t) exhibit significantly better cost-effectiveness compared to diesel and hydrogen fuel cell vehicles (FCEVs). Specifically, the transportation cost per hundred kilometers for a 4.5 t electric truck is only half that of a diesel truck, while the 49 t electric truck is approximately 100 CNY less than a diesel truck and 63 % less than a hydrogen fuel cell truck. However, the 18-ton (18 t) electric truck, due to its higher purchase cost, shows advantages only in a few regions. In terms of buses, both electric and hydrogen fuel cell models have higher transportation costs than diesel vehicles due to their higher fuel and purchase costs. Although FCEVs currently have higher costs, their economic competitiveness will be enhanced when the price of hydrogen drops below 40 CNY/kg. The study also found that the main factors affecting TCO are fuel costs and depreciation costs. Diesel vehicles are sensitive to fluctuations in fuel prices, while the TCO of battery electric vehicles (BEVs) is primarily influenced by electricity prices and temperature changes. High or low temperatures can affect the proportion of fuel costs in TCO by up to 4 %–6.56 %. The economic viability of FCEVs in each province is highly dependent on the price of hydrogen.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101726"},"PeriodicalIF":4.4,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777687","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}

Floating photovoltaic (FPV) systems emerge as a promising solution for rural electrification without land use conflicts, particularly in countries with abundant water resources.

The methodology employs QGIS software and integrates local weather data to evaluate the technical potential of FPV systems over Cambodia's water bodies, considering coverage scenarios from 1 % to 10 %. It also visualizes the spatial distribution of FPV potential in relation to population distribution, highlighting the transformative potential of FPV in addressing rural electrification challenges. The findings reveal substantial FPV potential in Cambodia. At a conservative 1 % coverage of suitable water bodies, the country could generate up to 12.23 TWh annually, increasing its power capacity by 1.2 times. The northwest region shows exceptional promise, with FPV potential meeting five times its rural electricity needs. The study provides an applicable methodology to other developing countries assessing FPV potential, guiding policymakers in exploring provincial geological resources and planning energy transition strategies.

This paper employs a framework for integrated power generation and water desalination expansion planning to account for such interdependence. The paper studies the economic and environmental impacts of a variety of decarbonization policies. The paper takes Kuwait as an example, with a target to reduce emissions by 7.4 % and 63 %, and increase renewable energy to 35 % and 50 % of peak load by 2035 and 2050 respectively. Emissions, planning costs, and operational costs, are studied under 6 different policies. Without any policy target, emissions in Kuwait are expected to increase around 165 % by 2050. In contrast, an optimized cost scenario will add an expected 39.5 % of new capacity, which will reduce the total cost and emissions by around 26 % and 23 % respectively. Other scenarios, representing different environmental and renewable energy targets, are included to provide a comprehensive understanding of different decarbonization pathways. The paper concludes that Kuwait can achieve its current emission reduction commitment, under the Paris Accord, with minimal cost, compared to a no policy case. More aggressive targets can also be achieved with reasonable costs.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"86 ","pages":"Article 101715"},"PeriodicalIF":4.4,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767768","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}

The multidimensional energy poverty characteristics were measured, and the mechanisms associated with the effects of energy justice factors on energy poverty were explored based on logistic regression modeling. The results showed that the incidence of energy poverty was 33.43 % and the low annual income of households was a key factor that pushed households into energy poverty. Energy justice played an important positive role in alleviating household energy poverty by enhancing the fairness of energy distribution, decision-making influence of women, and cognitive abilities. In particular, for every unit increase in distributive justice and recognition justice, energy poverty decreased by 1.7 % and 8.1 %, respectively. Procedural justice had a negative relationship with alleviating energy poverty. For every unit increase in procedural justice, energy poverty increased by 8.6 %.
