Abstract: Thermochemical energy storage (TCES) is considered as a promising technology to accomplish high-energy storage efficiency in concentrating solar power (CSP) plants. The high temperatures achievable by CSP are used to drive an endothermic chemical reaction, whose products are stored separately to be employed when needed for carrying out the exothermic reverse reaction, which releases the heat previously used. Among all the alternatives, the calcium-looping (CaL) process, based on the reversible calcination���carbonation of CaCO3, is one of...
