July 11 (Renewables Now) - Toshiba Energy Systems & Solutions Corporation, or Toshiba ESS, recently announced it has joined a four-company team that will implement a green hydrogen-related research project in Japan involving unused geothermal energy.

The subsidiary of Toshiba Corporation (TYO:6502) has teamed up with Kansai Electric Power Company Inc (TYO:9503), or KEPCO, as well as Kanden Plant Corporation and Iwatani Corporation (TYO:8088). KEPCO serves as the representative operator of the particular project, known as “Development of Technologies for Realizing a Hydrogen Society/Comprehensive investigative research.”

Toshiba ESS said it will undertake a study on hydrogen production using unused geothermal energy in Oguni-machi, Aso-gun, Kumamoto Prefecture, from July 2022 until March 2023. It will investigate the use of unused steam to produce stable and low-cost green hydrogen, which will then be applied to heat demands for industries in nearby areas.

The study is considered to be the first step toward creating a business model for the effective use of unused geothermal energy in the future.

The table below gives more information about each team member’s responsibilities as part of the project.

Name Role
KEPCO Hydrogen production capacity, hydrogen utilization study, and management of business feasibility assessment
Toshiba ESS Equipment layout/design study of Solid Oxide Electrolysis Cells (SOEC) hydrogen production equipment, steam turbines, and generators
Kanden Plant Equipment layout/design study of heat exchangers, heat pumps, and installation of steam/hot water piping, etc.
Iwatani Study of hydrogen storage/transportation, hydrogen stations, etc.
