After that, the yearly process heating requirement for the calcination process at each cement plant has been estimated using the actual annual cement production value. Finally, using the concept of a top-of-tower (TT) solar plant design, the total thermal energy that could be saved has been estimated as 771.35 Petajoule (PJ) /annum.

Meeting this escalating demand has become crucial, necessitating a shift towards sustainable energy use. Renewable energy sources have emerged as a popular choice for both off-grid and grid-connected installations as a means to bridge the efficiency gap. In this context, the present paper explores the potential of supplying electricity to a neighborhood in Cameroon comprising 100 homes through the integration of solar photovoltaic cells and electrolyzers. It is worth noting that Cameroon as a whole continues to grapple with severe social, economic, and physical challenges. Some regions within the country face significant obstacles in accessing quality healthcare, particularly for conditions like respiratory illnesses. This study employs an intelligent energy management method to design an optimal power flow control system, aimed at enhancing system stability during power outages and load fluctuations by effectively utilizing available storage capacity. The analysis was conducted using the Hybrid Optimization Model for Electric Renewable (HOMER) program. Our calculations reveal that a daily output of 0.123 kg mass of oxygen is produced, with renewable factor (RF) values indicating an 85.1 % integration of renewable sources, and the crucial parameter of Loss of Power Supply Probability (LPSP) reaching 0 %. These findings demonstrate that it is feasible for 100 homes to reliably generate and connect to the grid for electricity. Moreover, this research can serve as a solid foundation for the development of hybrid renewable energy systems to address the challenge of treating respiratory disorders such as COVID-19. These results underscore the significance of this study for various stakeholders, including decision-makers, policymakers, and investors in Cameroon and beyond. The ultimate goal is to promote national growth by improving socio-medical conditions.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"8 ","pages":"Article 100062"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772940023000309/pdfft?md5=ae338d09ff9511a8e5649570bca4b3e4&pid=1-s2.0-S2772940023000309-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135614902","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 cost of heat from parabolic trough collector systems is modelled using quasi-dynamic simulations in Polysun, and heat storage configurations are optimised. This study demonstrates that solar thermal projects would be viable alternatives to heavy fuel oil, diesel, gas, and even coal - should the cost of coal remain above US$250 /tonne (2020 real-term values).

South Africa produces 80 % of the world's manganese. The sintering of manganese in South Africa is fossil fuel intensive and emits nearly a million and a half tons of CO₂ per year. Concentrating Solar Thermal (CST) produces heat that can be utilised at a significantly lower cost than diesel firing, which is currently used for sintering. However, with CST being a nascent technology, most mining operations are reluctant to commit to its use. These risks can be minimised for the customer using an Energy Supply Company (ESCo or energy-as-a-service company) to provide heat to the mine.</p><p>For the ESCo, one of the most significant risks is the potential for the mining customer to terminate the contract before the end of the life of the CST energy supply asset. Using a solar field based on heliostats, such as the HelioPod™, that can be redeployed presents a level of insurance against this risk. In this analysis, the economic advantage of the HelioPod™ solar field-based CST system is compared to that of a conventional permanent pedestal-based heliostat field. The comparison was made assuming early termination of the contract and scenarios where the CST facility was redeployed once or twice during the nominal life of the facility. The discounted cash flow analysis shows that reusing the heliostat field leads to significant economic improvements. The study shows that the conventional permanent heliostat system reduces the project NPV@7 % by up to 28 % compared to the HelioPod™ system with one move in the project's life.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"8 ","pages":"Article 100060"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772940023000280/pdfft?md5=9e9df3e8489ae5621c8fb712045cbf2a&pid=1-s2.0-S2772940023000280-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92045823","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}

This project aims to conduct a comparative analysis of the performance of bifacial and monofacial solar panels under diverse conditions. The investigation involves examining the influence of varying albedo levels and the type of surface beneath the PV panels, including sand, white paint, black asphalt, or artificial grass. The renowned software tool PVsyst will be employed to simulate and analyze PV systems. The location selected for this study is An-Najah National University in Nablus, Palestine. The PV panels will be oriented towards the true south, and a tilt angle of 28˚ will be employed. Through meticulous simulations and thorough analysis, this research seeks to provide comprehensive insights into the contrasting performance characteristics of bifacial and monofacial solar panels across different environmental contexts. The ultimate objective is to contribute valuable knowledge regarding the suitability and optimal utilization of these PV technologies. The study aims to evaluate and compare the electrical output, energy yield, and overall performance of bifacial and monofacial solar panels under different scenarios. The project will analyze factors such as the energy gain achieved by the bifacial panels due to rear-side irradiance reflection, the impact of albedo on the performance of bifacial panels, and the influence of shading on both panel types.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"8 ","pages":"Article 100059"},"PeriodicalIF":0.0,"publicationDate":"2023-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50184502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
