A joint, government-supported study of the world’s largest hydrogen (H2) energy system by Iwatani Corporation, Toshiba Corporation and Tohoku Electric Power Co., Inc. has commenced.

Over the course of the next 12 months, the partners will investigate the configuration and specifications of a H2 energy system which will encompass the world’s largest H2 production system. The system will produce a maximum capacity equivalent to 10,000kW, largely relying on solar photovoltaic and wind power once in operation.

If the project is found to be feasible, the system will be deployed in Fukushima prefecture in Tohoku in the northeast region of Japan where it will convert renewable electricity into a large volume of H2 for long-term storage.

In addition to using the H2 to offset grid loads, the system will liquefy the gas for delivery throughout the North Pacific rim country, which the trio claims will “optimise H2 production, H2 electricity generation and H2 gas supply.”

Jun Miyazaki, General Manager of Iwatani Corporation, said the project will “contribute to the early establishment of a H2 economy” and added, “Drawing on our experience in the transportation, storage and supply of industrial H2, and the construction and operation of H2 stations, we will play an active role in expanding the use of H2 energy.”

The project has been selected for funding by Japan’s New Energy and Industrial Technology Development Organisation (NEDO).

In July, multinational Japanese conglomerate Toshiba Corporation unveiled the country’s largest alkaline water electrolysis H2 production system.
