“…In fact, compared with the WDSs powered by RERs, hybrid applications exhibit high flexibility of fresh water capacities, simple system design, and easy management. Delgado-Torres and García-Rodríguez [136] introduced seawater RO plants based on hybrid RERs of tidal/PV systems to promote WDSs with large capacities, as shown in Figure 14. Based on the annual simulations, a sensitivity analysis was conducted on the main parameters that affected the performance of WDS based on hybrid solar/tidal RERs for the WDS.…”

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.

“…The specific energy consumption (SEC), defined as the ratio of the freshwater yield to the electrical energy input, is expressed in kWh per m 3 of permeable water [57]. For the desalination, according to Delgado-Torres and Garcia-Rodriguez, 2022, "the daily freshwater production from a given power generation profile, depends on the rated capacity and the specific energy consumption (SEC)" [58]. Therefore, the SEC allows for evaluating the performance of the membrane desalination process and the contributions of the different sections of the plant, such as the high-pressure pumps, reverse osmosis membrane trains, and energy recovery devices, among others [59].…”

The natural potential of Chile—solar energy and 8 km of coastline—make the implementation of small-scale reverse osmosis desalination plants (RODPs) in coastal areas energetically supported with photovoltaic systems (PVs) feasible. This work considers a survey of the plants in Chile. As a demonstration of a RODP, a technical/economic evaluation is carried out, analyzing four possible cases in which different energy configurations are proposed: electric grid, diesel generator, and photovoltaic systems, without or with batteries. Finally, the challenges and opportunities of these plants are presented. The results obtained indicate that there are 39 plants in operation, which produce an average permeate water flow of Qp 1715 m3d−1. Solar Explorer, and Homer Pro software are used for a plant that generates 8 m3day−1 of permeate water, resulting in the conclusion that Case 3 is the most economically viable, as it has a useful life of 20 years and will have an annual solar contribution of more than 65%. The levelized cost of water production is 0.56 USDm−3 (RODP/PV) and 0.02 USDkW−1h−1 was obtained for the LCOE. Finally, this case contributes to the mitigation of climate change.

“…Therefore, an attractive way to ensure a sustainable desalination process is to use RES to power desalination plants. Studies have been published involving the coupling to desalination plants of other offshore renewable technologies, such as offshore wind [30], wave energy [29,31,32] and tidal energy [33]. However, to our knowledge, this is the first time that a real case of a grid-connected desalination plant supplied by an FPV system has been studied.…”

In places where water and land are scarce it is vital to look for innovative solutions that can ensure water production for agricultural purposes. This study considers the treatment of water using desalination processes to meet the quality requirements needed for irrigation purposes in agriculture. As the water is stored in a pond, an inland floating photovoltaic (FPV) system is proposed to meet the desalination energy demand. This system would enable energy production without using additional land that could otherwise be used for agricultural purposes. The use of FPV technology also reduces water evaporation, thus avoiding unnecessary energy consumption. To generate enough electricity to treat 12,000 m3/day of water, using an electrodialysis reversal desalination plant, a 1.85 MWp FPV farm is proposed. The results indicate that this FPV farm would generate 3,005,828 kWh per year while avoiding the emission of 58,300 tons of CO2 and the evaporation of 159,950 m3 of water during its 25-year lifetime. Such systems allow higher renewable penetration in the energy mix and preserve the original use of the land.
