In rural areas and remote locations suffering from pure drinking water scarcity.Water purification techniques are generally dependent on electricity, which relies on coal and gas plants, these poses a risk to the environment and society. Solar desalination is being recognized as the most practical way to deal with the scarcity of pure drinking water in all aspects of sustainable development. This paper describes the creation of a single slope solar still (SSSS) using opaque and crystal-clear toughened glass with a thickness of 6 mm as a cover and also another setup of a single slope phase change material (PCM)-based solar still (MSSSS). In this paper, a flat plate solar collector coupled with water heater is used to enhance the productivity of still. In this study, an experimental model has been developed to experimentally analyze exercise productivity performance of SSSS and MSSSS of MMIT Kushinagar, India on April 10, 2023 to April 15, 2023. Combination of stearic acid, lauric acid, and paraffin wax combined with CuO (nanoadditive) is used to enhance the solar still productivity. Also, basin temperature for different PCM's such as paraffin wax, lauric acid, and stearic acid are compared. Different combinations of PCM's and nanoadditives are compared to find the better productivity. It is observed that maximum output is obtained at 3:00 p.m. afternoon on experimental setup. Paraffin wax, stearic acid, and lauric acid still increases productivity by 38.8%, 20.3%, and 30.5%, respectively, when compared to simple solar still. On experimentation of various combinations, it is found that the use of PCM paraffin wax and nanoadditives CuO gives 55% better productivity compared to other combinations. This innovative system is suitable and ideal for desalinating water in isolated and rural locations with low traffic and limited demand.</p>\u0000 </div>","PeriodicalId":11765,"journal":{"name":"Energy Storage","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142174062","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}

To mitigate these problems, it is crucial to explore and implement alternative clean energy sources. This manuscript proposes a novel crayfish optimization algorithm (COA) for optimal scheduling in a hybrid power system that incorporates various renewable energy sources, like battery energy storage systems (BESS), fuel cells (FC), wind turbines (WT), micro turbines (MT) and photovoltaic (PV) panels. The importance of the work lies in its ability to optimize the entire operating costs of a grid-connected microgrid while improving the accuracy and efficiency of energy management. The COA method addresses economic dispatch problems and manages energy within the grid-connected microgrid, accounting for high levels of uncertainty. The proposed approach, tested using MATLAB Simulink, achieved a cost value of 252, outperforming existing methods such as GTO, PSO, SSA, and ALO.

The system that uses porous medium and PCM is called MSS-FPP, whereas the conventional system is called MSS-F. Rectangular fins are fixed above the absorber plate for both models. For MSS-FPP model, three different types of porous medium (stones, nuts, and black glass balls) are used in addition to paraffin wax filled inside circular tubes as a PCM.

The findings confirm that the performance of MSS-FPP model is better than MSS-F model by 41.32% (for water depth 3 cm) and 30.61% (for water depth 5 cm). The results also indicated that the water productivity of MSS-FPP model is higher than MSS-F model by 41.67% (for water depth 3 cm) and 30.65% (for water depth 5 cm).

It is found that the Fe₃O₄ nanoparticle additives reduce the onset of melting from 61.46°C to 57.03°C. The composite PCM is used for the cooling of a battery module of 6 substitute-18 650 batteries, and the cooling performance is experimentally and numerically investigated.
