摘要：

A binary cycle power generation system using high-temperature hot springs is attracting significant attention. The hot water or steam from the hot springs passes through a heat exchanger to evaporate a low boiling point medium, which then drives a turbine. To estimate the capacity of usable hot springs and their stability, one has been conducting modeling of hot springs areas based on geological and geochemical surveys. Various kinds of fluids are used as the medium in binary cycle power plants, including hydrofluorocarbon, hydrocarbons, and water-ammonia mixtures. In joint research with Geothermal Energy Research & Development Co. Ltd., researchers are conducting verification trials of a Kalina cycle power plant using a mixture of water and ammonia at Matsunoyama Hot Springs in Niigata Prefecture.
