Development of a small-size cogeneration system using thermoelectric power generation

Abstract

As energy and environment issues become serious, there is an urgent need to improve efficiency of industrial energy use as well as to alter lifestyles. To realize thermoelectric conversion technology that allows power generation from waste heat, we newly discovered thermoelectric oxides that possess high safety and durability at high temperatures. We then developed a prototype of a small-size generation system that functions at temperature range of 773∼1173K in collaboration with a private company.
