Renewable energy producer Axpo and electric utility Rhiienergie opened a green hydrogen production plant in Switzerland’s Graubünden canton.

The 2.5MW facility, claimed to be the country’s largest, is located next to the Reichenau hydropower plant in Domat/Ems and can produce up to 350 tonnes of green hydrogen a year.

The plant’s hydrogen is produced by water electrolysis, using green electricity from the adjacent hydroelectric power plant. The produced hydrogen is compressed in the plant, enabling its convenient delivery to refuelling stations and industrial customers in the future.

Axpo CEO Christoph Brand said, “There are still a few hurdles to overcome, but we’re convinced of this green, sustainable and renewable energy carrier’s potential.”

The new facility is connected directly to the Reichenau run-of-river hydropower plant, in which Axpo holds a majority stake.

Cantonal Councillor Dr Carmelia Maissen, head of canton’s Department of Infrastructure, Energy and Mobility, said, “The hydrogen plant fits perfectly with efforts to exploit the potential of green hydrogen in the Alpine region and the canton’s endeavours to achieve its climate and energy goals.”

Working with the SGV shipping company, Axpo is also planning the first hydrogen-powered vessel on Lake Lucerne in Switzerland. As part of this project, Axpo will supply the hydrogen needed to operate the boat.
