Development of Hydrogeological Information for Strategic Dissemination of GSHP System: Example of the Inawashiro Plain, Fukushima Prefecture, Japan Yutaro Torikoshi, Takeshi Ishihara, Akira Tomigashi, Naoaki Shibasaki

Abstract

Shallow geothermal utilization systems (especially GSHP systems) are used for heating and cooling, hot water supply, snow melting, and other applications. They are an energy-saving technology with the potential to decarbonize and reduce utility costs. However, GSHP systems have been slower to spread in Japan than in the other countries due to the high cost of GSHP system installation, lack of awareness, and lack of hydrogeological information. Therefore, the Shallow Geothermal and Hydrogeology Team of AIST is engaged in research on social implementation to popularize shallow geothermal utilization system, and this report introduces an example of such research.
