There is an urgent need for careful research on the synergy effects of EQTS and CETS to avoid conflicts between the systems and support scientific policymaking. Therefore, using a system dynamics model, this paper takes China's power sector as an example and studies the synergy effects of EQTS and CETS in quota allocation and compliance. The results show that the synergy mechanisms of the two systems can achieve synergy effects. (1) The quota allocation synergy mechanism can reasonably increase the production costs of thermal power manufacturers and promote energy conservation and emission reduction, with a maximum reduction of 2.9 % in energy consumption and carbon emissions compared to the benchmark scenario. (2) The quota allocation synergy mechanism avoids the excessive increase in compliance costs for thermal power manufacturers caused by the simultaneous implementation of the two systems of paid allocations, which seriously affects thermal power investment and generation, and drives up the electricity price. It also alleviates the negative impact of the EQTS on the carbon market performance. (3) The compliance synergy mechanism reduces the compliance cost of EQTS and CETS for thermal power manufacturers and increases thermal power generation. In addition, the simultaneous implementation of the quota allocation synergy and compliance synergy mechanisms of EQTS and CETS can also optimize the power supply structure and reduce the energy intensity and carbon emission intensity of the power sector.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101733"},"PeriodicalIF":4.4,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143824303","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}

Through a mixed-methods approach integrating national statistics, policy analysis, and case studies, spatial and socioeconomic disparities in clean cooking access were evaluated to assess the role of cultural, financial, and infrastructural barriers. The findings show that despite government efforts like the Gyapa Improved Cookstove project and National Liquified Petroleum Gas (LPG) Program, only 31 % of Ghanaians have access to clean cooking. Affordability remains a challenge to clean cooking as low-income households spend 3.1 % of their income on LPG compared to 0.7 % on wood. Other barriers include fragmented supply chains, limited access to modern fuels, inadequate infrastructure, and sociocultural preferences. Regional disparities persist, with northern Ghana's average household income (USD 1287 - 2276) limiting access to modern fuels compared to southern regions (USD 2144 - 6425). Successful models from Rwanda (Inyenyeri pellet cookstoves) and Kenya (pay-as-you-go LPG) projects highlight scalable solutions. Context-specific strategies are proposed to accelerate clean cooking transition. These strategies include scaling financial mechanisms such as carbon credit programs and rental or leasing schemes to reduce the cost of clean cooking, establishing local manufacturing firms, and behavioral initiatives addressing cookstove stacking practices and driving long-term adoption of clean cooking technologies. Energy policy revisions and regulatory frameworks must prioritize renewable energy integration for off-grid communities and strengthen the monitoring of policies, including Ghana's Renewable Energy Master Plan. By addressing these challenges and leveraging emerging opportunities, Ghana can reduce household air pollution, mitigate deforestation, and ensure equitable clean cooking access to advance the United Nations Sustainable Development Goals. This study provides actionable insights and strategies for policymakers and stakeholders to accelerate clean cooking transitions, emphasizing the need for holistic, collaborative governance, financing innovation, and culturally tailored interventions.</div></div>","PeriodicalId":49209,"journal":{"name":"Energy for Sustainable Development","volume":"87 ","pages":"Article 101727"},"PeriodicalIF":4.4,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821116","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 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}

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.
