R&D projects

Developing a hot dry rock system

The hot dry rock system is the next-generation of geothermal power plants by forming an artificial geothermal reservoir in the rocks to circulate water in the reservoir via two wells or more and extracting heat to generate electric power.

circulation and heat extraction test(2002)Since we started the fundamental study as part of the MITI’s Sunshine Program in 1974, we have worked on the research and development continuously. In 1995 and 1996, we succeeded a one-month circulation and heat extraction test at the Hijiori site located in Okura-mura, Yamagata Prefecture.
And now, The long-term circulation and heat extraction test that began from December 2000 and is scheduled to the end in of August 2002 is now in its closing stages.
