Toshiba to install PV hydrogen system at train station in Japan


Toshiba Corp has received an order for the "H2One" stand-alone PV hydrogen energy supply system from East Japan Railway Co. The system will be installed at Musashimizonokuchi station on the JR Nanbu Line in Kawasaki City; it is expected to start operations in spring next year.

Toshiba’s PV hydrogen solution consists of a rooftop PV system, storage battery, hydrogen production equipment, hydrogen tank and pure hydrogen fuel cell. The rooftop PV system has the capacity of 62 kW, and the hydrogen fuel cell generates 54kW. The system has electricity storage capacity of 1.8MWh, it can supply 24 liters of hot water per minute.

PV elements of the H2One system produce solar electricity, which is used to electrolyze water with the hydrogen production equipment; the produced hydrogen is stored in the tank. When there is no sun, the stored hydrogen is used to generate electricity with the pure hydrogen fuel cell. As a result, the system enables stable clean power generation using only water and solar power, the company says in the press release.

In case of a disaster, such as earthquake, if the train station is cut off the electricity grid, the stand-alone PV-hydrogen system will provide the much-needed uninterrupted energy supply. Any other time, the system will serve as an additional energy source.

Earlier this year, Toshiba’s H2One PV hydrogen system has been installed at a hotel in Sasebo City, Nagasaki prefecture. According to the company, the system generates enough electricity to power a 12-room hotel building throughout the year.
