A device for storing electric energy includes a heat reaction chamber. The heat reaction chamber can include a metal carbonate or a metal hydride material, a gas storage and an electric heater adapted to heat the reaction chamber, a Stirling engine including a heater head and adapted to be powered by the heated reaction chamber, a generator connected to and adapted to be driven by the Stirling engine. The device can be provided with a compressor arranged downstream of the reaction chamber and upstream of the gas storage adapted to increase the pressure of the gas flowing into the gas storage from the reaction chamber, and a pressure relief valve arranged downstream of the gas storage and upstream of the heat reaction chamber adapted to control the pressure of the gas flowing into the reaction chamber from the gas storage.
