Abstract
A process and apparatus for energy storage wherein thermal energy from solar or waste heat derived sources is passed in thermal exchange relation with a hydrated inorganic salt, such as calcium sulfate, endothermically dehydrating the salt thereby storing chemical energy and releasing the stored energy as heat by passing water under hydration conditions in contact with the salt exothermically hydrating the salt. The released thermal energy is substantially isothermal and available for any desired use involving thermal energy input. The process and apparatus of this invention is particularly suited to utilization of solar derived thermal energy.
