Abstract
A solar power system and materials capable of storing heat energy by thermochemical energy storage are disclosed. Thermal energy is stored as chemical potential in these materials through a reversible reduction-oxidation reaction. Thermal energy from concentrated sunlight drives a highly endothermic reduction reaction that liberates lattice oxygen from the oxide to form Ogas, leaving energy-rich, oxygen-depleted particles. When desired, the heat is recovered as the particles are re-oxidized in an exothermic reaction upon exposure to air. The system may be integrated with a power generation system to generate power.
