The system uses a beam-down parabolic dish concentrator to concentrate the solar radiation onto a ground-mounted receiver module, which has a secondary optical module consisting of a secondary reflector-light pipe system. The receiver module is a well-insulated tank consisting of a receiver in contact with a primary heat transfer fluid. The thermal energy stored in the receiver module is transported via a secondary heat transfer fluid to and from the cooktop via a tube-in-tube arrangement, which induces a thermosyphon effect. A multi-variable optical analysis through an efficient ray tracing methodology has been adopted to identify optimal design values of optical components such as parabolic dish concentrators, secondary reflectors, and light pipe-receiver assemblies. The optimal optical design parameters and their corresponding ray trace analysis results are elaborated. It was found that the designed beam-down parabolic dish concentrator system provides an ideal thermal energy of 10.3 kWh per day at an average DNI of 650 W/m².

Traditional biomass sources mainly used in most developing countries for cooking contribute to deforestation and indoor air pollution, necessitating a shift towards environmentally friendly alternatives. The study's primary objective is to evaluate the economic viability of using solar PV-based green hydrogen as a sustainable fuel for cooking in Ghana. The study adopted well-established equations to investigate the economic performance of the proposed system. The findings revealed that the levelized cost of hydrogen using the discounted cash flow approach is about 89 %, 155 %, and 190 % more than electricity, liquefied petroleum gas (LPG), and charcoal. This implies that using the hydrogen produced for cooking fuel is not cost-competitive compared to LPG, charcoal, and electricity. However, with sufficient capital subsidies to lower the upfront costs, the analysis suggests solar PV-based hydrogen could become an attractive alternative cooking fuel. In addition, switching from firewood to solar PV-based hydrogen for cooking yields the highest carbon dioxide (CO₂) emissions savings across the cities analysed. Likewise, replacing charcoal with hydrogen also offers substantial CO₂ emissions savings, though lower than switching from firewood. Correspondingly, switching from LPG to hydrogen produces lower CO₂ emissions savings than firewood and charcoal. The study findings could contribute to the growing body of knowledge on sustainable energy solutions, offering practical insights for policymakers, researchers, and industry stakeholders seeking to promote clean cooking adoption in developing economies.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"11 ","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772940024000122/pdfft?md5=3d10630cf43561e5f6c255bff47cb166&pid=1-s2.0-S2772940024000122-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141607791","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}

The study determined the network's hosting capacities and optimal points of injection for the reduction of active power loss and improvement of bus voltage profiles. The study showed that the existing Freetown distribution network had a hosting capacity of 34.6 MW with an active power loss reduction of 0.967 MW while the expanded Freetown distribution network had a hosting capacity of 59.57 MW with an active power loss reduction of 5.12 MW. Before the injection of the DSPs into both networks, most of the bus voltages were not within acceptable limits. However, with the intervention of the injected DSPs, bus voltages considerably improve. The study showed that the expanded Freetown distribution network is better for DSPs integration compared to the existing Freetown distribution network. To evaluate the impacts of the injected DSPs and to validate the model used, four network scenarios were considered.
