GeoKiln Partners with Chiyoda to Advance Commercial Hydrogen Recovery Using Stimulated Subsurface Technology

GeoKiln Energy Innovation Inc. (“GeoKiln”), a leader in engineered geologic hydrogen, has entered into a Memorandum of Understanding (MOU) with Chiyoda Corporation, one of Japan’s leading global engineering companies, to jointly conduct a conceptual study on hydrogen recovery and purification facilities using GeoKiln’s proprietary Manufactured Subsurface Hydrogen (MSSH™) technology.

The collaboration represents a major step toward the commercialization of stimulated geologic hydrogen, an emerging clean energy pathway that accelerates naturally occurring hydrogen-generating reactions within iron-rich subsurface rocks. Under the agreement, the two companies will design a commercial-scale surface hydrogen recovery and purification plant, integrating GeoKiln’s subsurface hydrogen generation models with Chiyoda’s world-class engineering expertise.

As part of the study, GeoKiln will provide detailed subsurface hydrogen generation data and stimulation models, while Chiyoda will lead the conceptual design of surface facilities, including energy balance calculations and commercial feasibility assessments. The study will also evaluate multiple hydrogen utilization pathways, including pipeline delivery, hydrogen-fired power generation, and fuel-cell-based electricity supply, laying the groundwork for future large-scale deployment.

Importantly, a major Japanese energy company is participating in the study from an offtake perspective, assessing potential hydrogen supply models and product specifications. This adds a critical commercial validation layer to the initiative and underscores growing interest in hydrogen supply diversification across Japan and international markets.

The project has been selected for support under the Tokyo Metropolitan Government’s “TiB CATAPULT” innovation program, aligning the collaboration with Japan’s Zero Emission Tokyo Strategy and reinforcing its relevance to national and regional decarbonization goals.

GeoKiln’s MSSH™ technology is designed to deliver predictable, controllable, and low-carbon hydrogen at costs potentially below $1.50/kg, while leveraging existing oil and gas drilling infrastructure and minimizing external energy and water inputs. Backed by Breakthrough Energy Fellows, GeoKiln is positioning stimulated geologic hydrogen as a scalable, dispatchable, baseload energy solution capable of supporting power generation, industrial demand, and future hydrogen networks.
