Abstract
Conditions and screening criteria of chemical heat storage material are introduced in the paper. Hydroxide is chosen as the research object. The thermodynamic parameters of the material have been calculated using HSC chemistry software. The main parameters are steering temperature and equilibrium constant. The results show that steering temperature of calcium hydroxide is 798 K, and its enthalpy difference is 100 kJ/mol. In the vicinity of this temperature, Gibbs free energy changes from the positive to the negative, indicating that above this temperature, the reaction can be spontaneous. Calcium hydroxide is a kind of ideal heat storage material as a large-scale storage of solar energy.
