Iwatani Establishes Solar Hydrogen Station on Saitama Prefectural Government Office Site
~Joint demonstration for a Ministry of the Environment project begins with Saitama Prefectural Government and Honda~

Iwatani Corporation (Head office: Tokyo and Osaka; President: Akiji Makino; Paid-in capital: 20 billion yen) has established Japan’s first solar hydrogen station on the site of the Saitama Prefectural Government Office, jointly with the Saitama Government (Governor: Seiji Ueda), Honda Motor Co., Ltd. (Head office: Tokyo; President & CEO: Takanobu Ito; Paid-in capital: 86 billion yen), and Honda R&D Co., Ltd. (Head office: Saitama; President, CEO & Representative Director: Yoshiharu Yamamoto; Paid-in capital: 7.4 billion yen).The opening ceremony was held today, attended by Governor Seiji Ueda of Saitama Prefecture, Managing Officer and Director Yoshiharu Yamamoto of Honda Motor Co., Ltd., and Iwatani Vice President Tadashi Danbara.


The solar hydrogen station manufactures high-pressure hydrogen at 35 MPa using Honda’s proprietary high-pressure water electrolyzing device, which runs on electricity from renewable energy (solar power generation).

It then stores the hydrogen for supply to fuel cell-powered automobiles. The project was undertaken on behalf of the Ministry of the Environment as a joint industry-government demonstration project.

It is Japan’s first system that does not produce any CO2 emissions throughout the entire process from hydrogen manufacturing to storage and supply. Demonstration tests will be conducted on hydrogen filling, driving, and electricity supply under actual urban environment conditions to inspect technical issues, community compatibility, and many other aspects with the aim of creating a low-carbon society.


Iwatani is responsible for the pressure reservoirs and other high-pressure gas facilities, security facilities for the hydrogen station, and filling control.


The hydrogen station is likely to play an important role with the proliferation of hydrogen stations and vehicles running on fuel cells from 2015.
