JOGMEC has selected six proposals for next-generation geothermal feasibility studies from its Feb. 2025 call, plus one additional award announced in October.
On October 24, 2025, Japan Oil, Gas and Metals National Corporation (JOGMEC) released the results of its public call for feasibility studies on next-generation geothermal technologies. The application period ran from 10 February to 28 February 2025, with six proposals selected.
The selected organisations are:
- Engineering Advancement Association of Japan (ENAA)
- CRIEPI, JAPEX, Geothermal Engineering Co. and Kajima Corporation
- GeoDreams Co., Ltd. and G-Pulse Co., Ltd.
- Akita University
- Chubu Electric Power Co. and Kajima Corporation
- Mitsui Energy Development Co., Ltd.
The studies cover deeper resource use, enhanced reservoir imaging, advanced drilling and related next-generation geothermal technologies.
Additional project selected under mid-2025 call
JOGMEC also confirmed the result of a separate tender held 23 June to 24 July 2025, selecting Toyo Engineering Corporation for an additional feasibility study. The award was published on 24 October 2025.
Announcements from GeoDreams and G-Pulse
GeoDreams Co., Ltd. published a statement confirming its selection for feasibility work under the programme, highlighting studies focused on advanced subsurface imaging. G-Pulse Co., Ltd., is working jointly with GeoDreams.
Study themes and participating institutions
According to the tender documents, the selected projects will evaluate:
- Deep-resource and high-temperature potential
- New drilling and wellbore concepts
- High-resolution subsurface evaluation
- Reservoir stimulation and heat-extraction methods
- Technology integration with broader energy systems
Participants include engineering associations, research institutes, universities, utilities and private geothermal developers, reflecting Japan’s technology-focused approach to geothermal development.
An additional public call has been issued on Nov. 10, 2025 “FY2025 Geothermal Power Resource Survey Subsidy Program 4th Call for Applications“.
