Abstract:
The invention concerns a method for storing or releasing thermal energy by chemical reaction according to which a flow of heat-transfer gas is circulated through a layer (10) of a first hygroscopic salt A, then through a layer (20) of a second hygroscopic gas B, the gas being reactive with salts A and B, the thermodynamic equilibrium curve of salt A being located further to the left than that of second salt B in a pressure-temperature phase diagram, the circulation of the flow of gas causing a dehydration or hydration reaction of both first salt A and second salt B.
