Recently, the thermal storage technology, which stores and utilizes a low-density energy around us, has been attracting attention. By combination with various environmental and energy technologies, a utilization technology of unused energy can contribute to the construction of a low-carbon society. The technologies to utilize unused heat can be thought of as the 3R use of heat. The recycle technologies include heat pumps, which reuse low-temperature heat as high-temperature heat with little electricity, and the thermoelectric power generation technology, which converts the thermal energy into electrical energy. The thermoelectric conversion elements (TCE) used in a thermoelectric power generation technology utilize the Seebeck effect, A high-temperature and a low-temperature heat source are required at both junctions of the TCE. For practical use, it is desirable that the fluctuation in the temperature of the high-temperature heat source is small. In this study, we propose a thermoelectric power generation system that can effectively utilize intermittent heat sources by using latent heat storage technology.
