Abstract: International audience; Thermal energy storage (TES) is a key factor for increasing the efficiency of concentrated solar power plants. TES using a reversible chemical reaction appears to be a promising technology for high energy density thermal storage (100–500 kW h m-3), at high temperature(up to 1000 °C) and during a long period (24 h to several months). This paper details an experimental study to carry out the reversible reaction Ca(OH)2(s) + DHr CaO(s) + H2O(g) in a fluidized bed (FB) reactor. The 4 micron Ca(OH)2 powder fluidization has...
