The thermal energy storage properties of dolomite, CaMg(CO 3) 2, from three sources (commercial, mined, and synthetic) are investigated as a potential solidgas thermochemical energy store for concentrating solar thermal power (CSP) plants. The reversible carbon dioxide release/absorption cycle can be used to store and release large quantities of thermal energy that can be harnessed near 550 °C.
