Air Liquide Norway built, owns and operates the hydrogen station at Rosenholm bus garage on a contract with Ruter.

Hydrogenics Corporation (Belgium) has provided two HySTAT(TM) 60 electrolyzers, in containers.

The electrolyzers support a complete electrolysis-based fueling station.  The electrolyzers, capable of producing 250 kilograms per day of pure hydrogen, are based at the Rosenholm bus garage in Oppegård Municipality in the suburb of Oslo, Norway.

The hydrogen refueling station commenced its service in May 2012 and provide hydrogen to operate fuel cell buses for a five year period. The project reduces noise and improves the air quality in the Oslo area, in addition to reducing harmful emissions from public transport. The hydrogen is produced at the station from electricity from renewable sources. The hydrogen fueling station delivers 100% certified green hydrogen.
