Asahi Kasei Begins Installation of Containerized Alkaline-Water Electrolyzer at Finland’s First Commercial Hydrogen Refueling Station

Asahi Kasei, a diversified global company, has begun installing its Aqualyzer™-C3, a containerized alkaline-water electrolyzer in the 1-MW class, at Finland’s first commercial hydrogen refueling station in Jyväskylä. The installation signals the start of the project’s next stage and represents a key step forward for Europe’s growing hydrogen ecosystem.

In July 2025, Asahi Kasei revealed plans to supply the Aqualyzer™-C3 electrolyzer to the Central Finland Mobility Foundation (Cefmof). Hydrogen produced by the system will help Cefmof expand support for hydrogen-powered transportation in the region, including fuel-cell vehicles and hydrogen buses. The initiative is expected to serve as a model demonstrating how hydrogen can be used effectively in cold climates and within the mobility sector.

The electrolyzer will be run by Cefmof Hydrogen, a wholly owned subsidiary of Cefmof, with operations expected to begin in summer 2026. Once operational, the unit will generate around 400 kg of hydrogen per day, sufficient to refuel roughly three fuel-cell vehicles per hour.

Drawing on more than five decades of experience in large-scale chlor-alkali electrolysis, Asahi Kasei is leveraging its materials and systems expertise to advance hydrogen production technologies. The company is developing a multi-modular system concept, linking several 10-MW-class pressurized alkaline water electrolyzers under the Aqualyzer™ brand. Pilot projects in Fukushima and Kawasaki have already demonstrated the system’s strong reliability and efficiency under real-world conditions, including operation with fluctuating renewable energy supplies.

In 2024, Asahi Kasei expanded its lineup by introducing Aqualyzer™-C3 electrolyzers ranging from 1 to 7.5 MW. This addition enables the company to address the evolving needs of hydrogen markets worldwide, covering applications from smaller installations to large-scale projects.
