Abstract
A heat storage system has a heat source that generates heat and releases the heat to a first heat medium and a heat storage body that stores heat. The heat storage body changes to a first phase in a solid state when a temperature of the heat storage body is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when a temperature of the heat storage body exceeds the phase transition temperature. The heat storage body stores or releases heat due to a phase transition between the first phase and the second phase. A mode of operation of the heat storage body is switchable between a heat storage mode in which the heat storage body stores heat of the first heat medium and a heat release mode in which the heat storage body releases the heat stored in the heat storage body to a heat transfer target.
