Global warming, and the energy crisis, both caused by the unregulated overconsumption of fossil fuels, are some of the main problems humanity has to face along with freshwater shortage. The importance of safe access to freshwater and various forms of energy to the survival of modern societies is undeniable. Water- and energy-related technologies are independent, but thermal energy storage can bind such technologies. Salts, which are well-known phase-change materials that can be used as thermal energy storage media, can be extracted from the brine produced by desalination plants, which is usually rejected into the environment. Evaporation, electrodialysis, membrane distillation-crystallization, and adsorption/desorption are suitable techniques for extracting salts from brine in conjunction with desalination. Obtained salts can be used as phase change materials in thermal energy storage units. Salt-based thermal energy storage units can be integrated into concentrated solar power plants, geothermal power plants, fossil fuel, and biomass fuel power plants, load-following nuclear power plants, and various industrial processes for energy production and optimization. Although there are many papers on molten salt-based thermal energy storage, the direct utilization of salts extractable from the brine produced by desalination plants for thermal energy storage units has not been thoroughly investigated. In order to provide a guide for researchers in investigating such systems, this paper reviews salt extraction technologies in conjunction with desalination, applications of salt-based phase change materials in thermal energy storage, and challenges and perspectives of binding desalination plants with energy production or optimization systems using thermal energy storage. • Desalination plants produce brine which can be used to obtain salts. • Salts are phase change materials that can be used in thermal energy storage. • Salt-based thermal energy storage units can be used in various applications. • Co-generation of water and electricity is possible using thermal energy storage. • Developing thermal energy storage technology demands a multidisciplinary approach.
