Joint Consideration on advanced Geothermal technology with Chevron

September 26, 2022 Project

Mitsui Oil Exploration Co., Ltd (MOECO), and Chevron New Energies International Pte, Ltd. (Chevron) today announced the signing

of a Joint Collaboration Agreement to explore the technical and commercial feasibility of advanced geothermal power generation in



Building on Chevron and MOECO's long-standing relationship, the new collaboration will study geothermal resource potential across

Japan and will evaluate the effectiveness of Advanced Closed Loop (ACL) technology for a future joint pilot project in Japan. Both

companies may also assess potential collaboration for advanced geothermal technology opportunities globally.


Unlike conventional geothermal projects, which use traditional steam turbines requiring high temperatures often found in concentrated

locations limited by geological characteristics, ACL can potentially enable access to geothermal resources at a wider range of

temperatures and geologies through the application of alternative technology above and below the surface.


"Chevron and MOECO share a goal of delivering lower carbon energy solutions, while meeting the need for reliable, affordable

energy," said Barbara Harrison, vice president of Offsets & Emerging, Chevron New Energies. "This collaboration provides an

opportunity for Chevron to combine its subsurface capabilities and technologies with MOECO's intimate knowledge Japan's

geothermal potential resource geology and its long history of responsible resource development. The joint team will have the

opportunity to test emerging geothermal technology in a real world setting with significant scaling up potential."


"MOECO entered the geothermal business in 2012 and has been expanding its geothermal portfolio  since then. In parallel with

conventional geothermal, we have been studying ACL technology for many years and we believe this collaboration with Chevron

utilizing ACL technology could unlock tremendous geothermal resources in Japan." said Hirotaka Hamamoto, Chief Executive Officer

of MOECO. "This joint collaboration with Chevron, who has been a valued partner of MOECO for several decades in the energy

industry, is intended to open a new chapter in the geothermal industry as MOECO aims to continue contributing to an environmentally

sustainable world as a member of the Mitsui & CO's group companies."
