Misawa Solar System Maintenance (MSM) had a ceremony to celebrate the completion of a hydrogen station and the reuse/recycle line of solar panels in Oirase-cho, Aomori Prefecture, Japan, Oct 3, 2017.

MSM is a business cooperative based in Misawa City, Aomori Prefecture, Japan. It deals with O&M (operation and maintenance) services for solar power plants.

The hydrogen station is a facility that fills fuel-cell vehicles (FCVs) with hydrogen. It was installed in 2-chome, Toyohara, Oirase-cho. The facility is "Smart Hydrogen Station (SHS)," which was co-developed by Honda Motor Co Ltd and Iwatani Corp. This is the first time that a stationary hydrogen station has been installed in the northern Tohoku region of Japan.

The SHS can produce 1.5kg of hydrogen per day and store 19kg of hydrogen. It charges an FCV with a pressure of 35MPa. On the premises of the station, there are 30kW of solar panels and a lithium-ion (Li-ion) storage battery having the same output. Water is electrolyzed by solar electricity to produce hydrogen. The total capacity of the solar panels is high enough for producing all the hydrogen supplied to FCVs, according to MSM.

The solar panels and the battery are reused products. The solar panels were manufactured by SolarWorld Industries GmbH and removed in Hokkaido after being damaged by a disaster. The Li-ion battery is Toshiba Corp's "SCiB."
