Abstract

This chapter uses the first and second laws of thermodynamics along with Le Châtelier's principle of chemical equilibria to illustrate how the high energy density of chemical substances may be exploited to store solar thermal energy. Storing solar thermal energy in chemical substances comes with significant technical and ...
