Abstract – In most recent couple of decades, Thermal Energy Storage (TES) has turned into the topic of most extreme significance in many engineering applications and has been demonstrated as the subject of great interest of research work. Sorption systems (adsorption or absorption) are reliant on a chemical processes and subsequently are also named as chemical heat storage. The Chemical Thermal Energy Storage (CTES) incorporates sorption and thermochemical systems. In sorption energy storage, heat is stored by dissociation reaction and is recovered in chemically reverse reaction. Sorption TES has high storage densities than other types of TES, in this way permitting huge amount of thermal energy to be stored by utilizing small amount of storage substances. Energy storage dependent on chemical reaction is especially reasonable for long term and short term storage applications, e.g., solar heat storage, daily waste heat storage, etc. Amid the storage duration, since the process includes no heat losses, storage is typically completed at surrounding temperatures. This paper reviews only the open sorption TES utilizing MgCl2.6H2O salt hydrate with an interest in comparing different heat storage materials, latest advancements in materials, their characterization, their limitations and conceivable changes for their applications.
