Northernmost hydrogen station in Honshu

Oirasecho, Aomori Prefecture, is located along the Oirase River, which starts at Lake Towada, and is blessed with abundant nature. Surrounded by Hachinohe, Misawa and Towada cities, the town is easily accessible. On October 3, 2017, a stable hydrogen station, the northernmost one in Honshu, was developed in the town, and its completion ceremony took place.

Equipped with solar panels of 30kW and Li-ion batteries of 30kW in the same site, hydrogen is made by water electrolysis using electricity generated by the solar power system. According to the plant, the capacity of the installed solar panels will be sufficient to generate almost all hydrogen that will be provided (Fig. 1 & 2).

This hydrogen station was constructed by Misawa-shi Solar System Maintenance Co-op (Misawa City, MSM). MSM is engaged in everything from construction and operation to outsourced operation and maintenance (O&M) of mega- (large-scale) solar power plants. In addition to the mega-solar business, the company is planning to operate hydrogen stations and enter the solar panel reuse and recycling business.

In fact, the completion ceremony of the hydrogen station doubled as the completion ceremony of a panel reuse and recycling line, after which visitor tours were conducted at the recycling facility completed in Misawa City.
