“…Similar successful industrial applications have been reported from other parts of the globe. For example, reaching up to 90 °C in a flotation cell using an annual solar insolation of 1600 kWh/m 2 in Granada, Spain (Alcaraz et al, 2018) and achieving an average air tem-perature of 40 °C utilizing an annual solar insolation of 1500 kWh/m 2 in Victoria, Australia (Bawahab et al 2019). Figure 2 provides the global distribution of SGSP projects.…”

Advancement of renewable energy is critical for sustainable development. This paper evaluates the feasibility of saline gradient solar ponds (SGSP) as an alternative energy source for Saskatchewan, Canada. The main achievements include global appraisal of SGSP from theoretical and practical perspectives, assessment of salinity and climatic criteria for SGSP potential, understanding of heat transfer mechanisms affected by thermophysical properties, and numerical modeling to simulate transient heat diffusion in SGSP. Results indicated that Saskatchewan is ideal for thermal energy harvesting from saline water bodies because of high solar insolation (1100 to 1400 kWh/m 2). The solar radiation in such systems is captured under a salt concentration gradient. Locally, ten potash tailings sites (360 g/L or 36% salt) and two saline water lakes (250 g/L or 25% salt) are potentially suitable for SGSP deployment. It was found that thermal conductivity increases with temperature but decreases with water salinity increase (0.55 to 0.675 W/mK) and the opposite is true for density (1000 to 1200 kg/m 3). Similarly, specific heat capacity slightly increases with temperature and inversely correlates with salinity (3000 to 4200 J/kg K). Furthermore, the heat diffusion model adequately simulated the temperature distribution for a typical SGSP in a potash tailings containment facility. For the investigated month of July (highest solar insolation), the temperatures increased from an initial value of at 20 to 52 º C at top to 37 º C at bottom. A comprehensive risk assessment of this method is required to protect air, water, soil, and biota at specific sites.

“…They also compared the environment and economic analysis of both the types of SP in their review paper. Bawahab et al 23 had used the SP for salt production in the climate conditions of Australia. They showed that the novelty of their work was the use of a heat pump with the SP.…”

A solar pond (SP) is a remarkable growth of renewable energy technology that has stored solar energy for storage purposes and is used in many solar thermal applications. It is also utilized for many purposes, such as heating, cooling, space heating, air conditioning, and many more. The present paper shows the use of an SP to improve the yield of solar still (SS) by providing hot water through the heat energy stored in it. It also reveals the use of shallow and mini SPs with SS to improve yield. Various future research works on SS using SPs have also been included in this paper. From the current review paper, it was concluded that the SP increases the yield of the SS.
