Asahi Kasei has begun installing its 1 MW-class Aqualyzer C3 containerized alkaline-water electrolyzer in Jyväskylä, Finland, marking a significant milestone for Europe’s hydrogen infrastructure.

Located at Finland's first commercial hydrogen refueling station, this project signifies the start of the next phase for the Central Finland Mobility Foundation (Cefmof), with full operations expected in the first half of 2026.

In July 2025, Asahi Kasei announced that it would supply its Aqualyzer C3 electrolyzer to the Central Finland Mobility Foundation (Cefmof). Using hydrogen produced by the Aqualyzer C3, Cefmof plans to expand support for local hydrogen-powered transportation (such as fuel cell vehicles and hydrogen buses).

The project will serve as a case model for the potential of hydrogen utilization in cold climates and the mobility industry. The electrolyzer will be operated by Cefmof Hydrogen, a wholly owned subsidiary of Cefmof, and operations are scheduled to start in the summer of 2026. The system will produce 400kg of hydrogen per day, enough to refill approximately 3 fuel cell vehicles (FCVs) per hour.

Kenji Takeda, Executive Officer of Asahi Kasei responsible for Business Development of the company’s Green Solution Project, commented, “We are delighted that the installation of the hydrogen production plant in Jyväskylä is now moving into the implementation phase. This milestone advances our decarbonization efforts and supports the development of the hydrogen ecosystem in Central Finland. It furthermore represents a significant step in demonstrating the reliability and scalability of Asahi Kasei’s water electrolysis technology.”

“This marks a significant milestone, as only a limited number of hydrogen production facilities are currently in operation in Finland. Cefmof Hydrogen Ltd. is among the first operators in Finland to deploy a containerized alkaline water electrolysis system of this scale for hydrogen production,” says Lauri Perämäki, Deputy Member of the Board of Cefmof Hydrogen Ltd.

With over 50 years of experience in large-scale industrial chlor-alkali electrolysis, Asahi Kasei is applying its extensive material and system expertise to hydrogen production. The company is pursuing a multi-modular approach, connecting several 10 MW-class Aqualyzer pressurized alkaline water electrolyzers.
