The Central Finland Mobility Foundation (Cefmof), founded by the City of Jyväskylä and Toyota subsidiaries, said the containerised unit supplied by Japanese tech firm Asahi Kasei would be installed and integrated at the site in Jyväskylä through the spring and summer.

The electrolyser will be installed next to a hydrogen refuelling station that has operated since summer 2025, supplying a fleet of five hydrogen fuel cell buses.

Since opening, the station has relied on green hydrogen deliveries from P2X Solutions’ plant in Harjavalta, nearly 300km away. Deliveries will continue to supplement on-site production.

Once operational, the Asahi Kasei electrolyser will produce up to 400kg of hydrogen per day on site. Cefmof has said it could add additional units in the future to scale production.

The site is also equipped with a single 20-ft hydrogen storage container from Norway-based Hexagon Purus. Swedish biogas company Metener Service will also supply a hydrogen compressor to pressurise the electrolyser’s output.

Deputy board member of Cefmof, Lauri Perämämki, said the installation was a “significant milestone” due to the limited number of hydrogen production projects in the region.

“Cefmof Hydrogen is among the first operators in Finland to deploy a containerised alkaline water electrolysis system of this scale for hydrogen production.”

For Asahi Kasei, it will be one of the first European installations of its small-scale electrolyser systems. The systems were added to its portfolio in 2024 following a memorandum of understanding with Italy’s De Nora to focus on small-scale electrolysers.
