Japan's energy and technology innovation agency NEDO has issued a call for applicants on a survey on the characteristics of supercritical geothermal fluids with deadline of August 16, 2022.
Announced on August 3, 2022, the New Energy and Industrial Technology Development Organization (hereinafter referred to as “NEDO”), a Japanese national research and development agency, is soliciting applicants for the following projects from the general public.
Survey on the characteristics of supercritical geothermal fluid
The 6th Strategic Energy Plan points out the importance of next-generation geothermal power generation technologies such as supercritical geothermal power generation toward the “realization of carbon neutrality by 2050.” Supercritical geothermal power generation uses geothermal fluid in a supercritical state (temperature of 374°C, pressure of 22 MPa or more) deep underground (approximately 3 to 5 km) in a volcanic area, so it is larger than conventional geothermal power generation. It is expected to contribute to the further expansion of the introduction of geothermal power generation.
Currently, NEDO is conducting research and development for resource quantity and economic evaluation in four regions with high geothermal resource potential (Hachimantai, Kakkonda, Yuzawa Nanbu, and Kokonoe), with the aim of realizing supercritical geothermal power generation. Of these, for resource assessment, it is necessary to understand the characteristics of geothermal fluids in addition to understanding the location and shape of reservoirs. It is the current situation that it is not accumulated.
Therefore, in this survey, we will conduct a survey to understand the characteristics (origin, generation process, amount, etc.) of the supercritical geothermal fluid estimated in each region, which will contribute to the geothermal resource assessment in the four regions.
