BASELOAD POWER JAPAN: SHIKA POWER PLANT
The Shika Power Plant in the Kumamoto region of Japan is a geothermal power plant with a 2 MWe flash system that generates electricity using a steam turbine. After extracting most of the energy from the steam, hot water remains at approximately 115°C. Climeon’s HeatPower technology is applied as a binary bottoming cycle, utilizing the remaining heat from this hot water to produce up to150 kWe of additional electricity. This process increases the overall efficiency of the power plant by capturing and converting more energy before the water is re-injected into the ground. The integration of Climeon’s HeatPower system demonstrates how binary cycle technology can enhance the performance of high-temperature geothermal flash systems.
