“…These interactions are more related to the physical properties of the membrane and the dissolved substances than chemical reactions in the traditional sense. A PV desalination plant is depicted in Figure 5 [40]. The system usually consists of the basic elements of solar panels, which constitute the main source of energy; the desalination unit that is used to convert salt water into fresh water through the distillation process; storage tanks for the seawater feed and the fresh water product; piping and valves to link and regulate the flow of water; and several control and monitoring systems to optimally regulate the desalination process, increasing efficiency and lowering cost at a reliable and secure level [37].…”

Solar energy, derived from the inexhaustible energy of the sun, has emerged as a promising solution to mitigate the environmental challenges posed by fossil fuel consumption and global climate change. This work explores the underlying principles of solar energy exploitation, focusing on energy collection technologies as the primary means of solar energy conversion. The physics of the state-of-the-art mechanisms, the photovoltaic effect, and the advancements that have driven the transformation of solar energy into a viable and sustainable alternative energy source are also examined. Through a comprehensive review of relevant literature and pioneering research, this study highlights the immense potential of solar energy and its role in shaping a cleaner, greener future. Towards de-carbonization, the various exploitation technologies are divided into direct and indirect in order to optimize resource utilization. Accounting for the most important advantages presented, solar-based utilization processes are perhaps the only ones that provide access to energy for all to satisfy their vital needs. As nations continue to embrace solar energy and invest in its development, we move closer to achieving a more sustainable and environmentally friendly world for generations to come.

“…A solution concentration of 10,000 mg L −1 of TDS was prepared by mixing municipal tap water and synthetic salt (Instant Ocean Sea Salt, Carolina Biological Supply Company, Burlington, NC, USA) containing all the elements of the sea. Membrane performance was evaluated by calculating inherent equations, which serve to determine membrane performance during the process [13,[23][24][25][26].…”

Water scarcity has prompted the use of desalination technologies such as reverse osmosis (RO) due to its low energy requirement and high production rate. In the present article, the concentration polarization factor (β) was evaluated in RO processes, in batch and continuous systems and with an alternating current (AC) and direct current (DC) to desalinate water with 10,000 mg L−1 of total dissolved solids (TDS). In DC, the power variation and its effect on β was evaluated by simulating intermittent solar photovoltaic radiation. The specific energy consumption (SEC) in kWh m−3, the water quality in mg L−1 of TDS and β were evaluated. In a batch process, 3.98 and 3.85 kWh m−3 were required for AC and DC, respectively. In a continuous process with AC, 3.79 kWh m−3 was required, and for DC, it decreased by 17.93%. The permeate water quality was evaluated with reference to the Mexican standard of 1000 mg L−1 in TDS. A TDS concentration of 1631 mg L−1 was found in batch–AC processes, and a TDS concentration of 747 mg L−1 was found in batch–DC processes. In continuous AC–DC processes, the TDS concentration did not exceed 1000 mg L−1. The permitted β limit was 1.2. The result of the batch process when using DC was 1.007, while for AC, it was 1.022. In continuous processes with AC, the β was 1.008, and in DC, it was 1.012. The results prove that the intermittency due to power variation is an alternative way to reduce the concentration polarization factor, with effects that include a reduction in the specific energy consumption and an improvement in the permeate water quality.

“…RO-WDSs function with a nominal load of constant pressure and flow rate of the feed water to the membranes, while a variable operating load of RO-WDSs, i.e., different flow rater and feeding pressures, introduces outstanding results [20]. The benefits of combining wind energy [21] and photovoltaic (PV) panels [22] with RO-WDSs have already been implemented. Both gravitational potential and wind energies were combined in RO-WDSs [23].…”

Energy Storage for Water Desalination Systems Based on Renewable Energy Resources

Recently, water desalination (WD) has been required for the supply of drinking water in a number of countries. Various technologies of WD utilize considerable thermal and/or electrical energies for removing undesirable salts. Desalination systems now rely on renewable energy resources (RERs) such as geothermal, solar, tidal, wind power, etc. The intermittent nature and changeable intensity constrain the wide applications of renewable energy, so the combination of energy storage systems (ESSs) with WD in many locations has been introduced. Thermal energy storage (TES) needs a convenient medium for storing and hence reuses energy. The present work provides a good background on the methods and technologies of WD. Furthermore, the concepts of both thermal and electrical energy storage are presented. In addition, a detailed review of employing ESSs in various WD processes driven by RERs is presented. The integration of energy storage with water desalination systems (WDSs) based on renewable energy has a much better capability, economically and environmentally, compared with conventional desalination systems. The ESSs are required to guarantee a constant supply of fresh water over the day.
