Chemical reaction heat storage energy density

Thanks to the highest density of solids, higher storage energy density is achieved that is more compact and easy to handle devices. The main difference to sorption proce ses is the chemical phase change - a new compound is formed. This process takes place for a givereaction system and gas pressure at a constant temperature. Abstract The chapter addresses the main issues dealing with four types of reversible processes, such as dehydration of salt hydrates and hydroxides, thermal decomposition of oxides and perovskites for thermal energy storage as example of thermochemical processes covering a broad range of.
