“…The pure water requirement is increasing dramatically in the contemporary globe compared to the previous century due to expansion in population density, industrial innovation, and agricultural requirements. According to a recent study, over 3.2 billion people live in villages to severe water shortages and water‐restricted agricultural activity 9–11 . Hence, it is critical to devise a method that can meet the demand for freshwater without threatening long‐term growth.…”

The use of different energy storage materials can have a high effect on the water productivity of solar desalination. This study evaluates the impact of magnetic powders on modified solar still (MPSS) performance and compares the results with conventional solar still (CSS). Black iron oxide magnetic powder was selected to increase solar radiation absorption. The black iron magnetic powder simultaneously acts as a thermal storage material and a porous absorber medium. The thermal energy stored in the magnetic powder improved the performance of the MPSS during peak solar irradiation hours, resulting in higher productivity. The results showed that the thermal performance of MPSS was higher than CSS. The MPSS exhibited a 39.8% higher evaporative and 14.5% higher convective heat transfer rate compared with CSS. Results showed that the cumulative water productivity of MPSS was 31.2% greater than CSS. Also, the energy and exergy efficiencies of MPSS were improved by 18.9% and 19.04%, respectively, compared with CSS. Moreover, the predicted payback period in MPSS and CSS were 3.2 and 4.3 months. Additionally, the CO 2 reduction of MPSS was improved by approximately 45.53% compared with that of CSS. The results also showed that the exergoeconomic parameter of MPSS and CSS with energy base was equal to 33.1 and 24.56 kWh/$, respectively.

“…Phase change materials (PCM) such as inorganic, organic, and eutectic substances can be used as latent heat storage material. Gravels, mild steel scraps, eggs shells, egg shell powder, gravel sand, El Oued sand grains, dye, pebbles, iron chips, and sand can be used as sensible heat storage (Murugavel et al 2008 , 2010 ; Samuel et al 2016 ; Dhivagar et al 2020a , b ; Balachandran et al 2021 ; Dhivagar et al 2021 ; Dubey and Mishra 2021 ; Attia et al 2022 ; Thakur and Sathyamurthy 2022 ). However, PCM had a bigger impact on the solar desalination (El-Sebaii et al 2009a ).…”

The paucity of freshwater is very dangerous in the coming years. Many coastal countries suffer from a scarcity of freshwater. Solar desalination is the cheapest way to produce freshwater from any type of non-drinkable water (brackish water and seawater). In this work, single-slope single-basin solar still for seawater desalination was examined under Upper Egyptian weather conditions of Qena City (latitude 26.16°, longitude 32.71°). The main goal of the work is to compare the performance of conventional solar still, solar still supported with PCM, and solar still supported with local clay material to augment the solar still yield during both daytime and nighttime periods of operation. The results demonstrated that the total production of desalinated water from the simple conventional solar still, the solar still with PCM, and the solar still with local clay reached about 3885, 4704, and 5388.6 ml/m2, respectively. Moreover, compared to the conventional solar still, the yield was increased by about 21% when using the PCM, and about 38.7% when using the local clay material. Furthermore, it can be observed that the daytime productivity in the case of solar still supported with local clay was higher than that for the solar still supported with PCM, while the nighttime productivity was higher in the case of solar still supported with PCM compared with solar still supported with local clay. Moreover, the average daily efficiency of conventional solar still, solar still with PCM, and solar still with local clay reached about 34, 41.2, and 47%, respectively. Therefore, it is recommended to use the solar still with local clay for seawater desalination in such arid and hot climate of Qena City.

In the present manuscript, performance studies of Solar Still (SS) were studied for the climatic conditions of Erode, India. Three different experiments were conducted:Conventional SS (CSS), CSS incorporated with blue metal stones, and CSS incorporated with tar-coated blue metal stones. Furthermore, the energy and exergy efficiency of the CSS is evaluated. The daily-distilled yield by incorporating the tarcoated blue metal stones in CSS is 3.21 Kg and blue metal stones in CSS is 2.89 Kg with augmentation of 34.4% and 27%, respectively than the CSS. The distilled water production during daytime (8 a.m.-6 p.m.) from the CSS, CSS incorporated with blue metal stones, and CSS incorporated with tar-coated blue metal stones is 2.02, 2.59, and 2.83 kg, respectively. Similarly distilled water production during nighttime (7 p.m. to 11 p.m.) is 0.08, 0.29, and 0.39 kg, respectively. The distilled water production during daytime and nighttime from the CSS incorporated with tar-coated blue metal stones and CSS incorporated with blue metal stones are 28.3%, 22%, 78.6%, and 71.7% higher than the day-time and night-time yield from the CSS. Also, the energy and exergy efficiency of the CSS incorporated with tar-coated blue metal stones and CSS incorporated with blue metal stones is 21.6% and 1.63%, and 20% and 1.4%, respectively.
