Japan: Alkaline-Water Electrolysis Asahi Kasei Starts Second Hydrogen Demonstration Plant
Following the start of a demonstration project in Herten, Germany, in April 2018, Asahi Kasei launched an alkaline-water electrolysis demonstration project in Soma, Fukushima, Japan. The new project aims at the development of a large-scale production system for green hydrogen by using power input from renewable energy sources.
Düsseldorf/Germany — The project is a joint project with the Japanese IHI Corporation. The alkaline-water electrolyser is installed at the Soma IHI Green Energy Center, which was launched in April 2018 by Soma City and IHI. It features large electrodes, maximum electrolytic capacity of 120 KW and hydrogen production capacity of 25 Nm3/h. Green hydrogen is produced by only using electric power from renewable energy sources.
The project 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). In previous tests, Asahi Kasei confirmed that the system enables high energy efficiency of over 90 %. The company claims that it aso features outstanding responsiveness with fluctuating power input which made this system suitable for power input from renewable energy sources. The demonstration project is expected to verify the practicability of the alkaline-water electrolyser employed in an integrated configuration with an actual photovoltaic power generation facility. The project is scheduled from April 2018 to March 2020.
Asahi Kasei intends to utilize the know-how gained through this demonstration project to advance the commercialization of an alkaline-water electrolysis system featuring the world-leading scale of 10 MW in a single unit.
The demonstration project in Soma is the company's next step in the expansion of its green hydrogen business. On April 27, Asahi Kasei Europe started a demonstration project with an alkaline-water electrolyser in the Hydrogen City of Herten in the state of North Rhine-Westphalia, Germany. The joint project together with the Hydrogen Competence Center h2herten simulates the production of hydrogen from wind energy and contributes to the development of an electrolysis system for the production of green hydrogen on a large scale.
