Asahi Kasei begins trial operation of green hydrogen plant


Japanese chemical company Asahi Kasei has begun trial operation of an alkaline water electrolysis plant for the production of green hydrogen (H2) using renewable energy jointly with IHI Corp. in Soma, Fukushima.

With large electrodes, maximum electrolytic capacity of 120 KW, and H2 production capacity of 25 Nm3/h, the plant is installed at the Soma IHI Green Energy Centre launched in April 2018 by Soma City and IHI.

“The plant uses a large-scale alkaline water electrolysis system having the world’s largest electrodes developed on commission by Japan’s New Energy and Industrial Technology Development Organization (NEDO), which continues to support its trial operation.
