About us

Since it was founded in 2004, Hydrogen Refueling Solutions (HRS), previously known as TSM, has provided hydrogen refueling station solutions for every type of vehicle (captive fleets, lorries, buses, passenger cars, etc.) for the transportation, industrial, storage and energy markets.

A new premises located in the Saut du Moine business activity area in Champagnier (in the Isère department), in a 2.6 Ha plot granted by the Grenoble-Alpes Métropole. A new production unit (10,000 sqm) will finish construction in this new space by autumn 2022, alongside offices (3,300 sqm), amenity areas (1,000m sqm) as well as a refueling station accessible to the general public.
This site will include a 2,000-sqm collaborative R&D center to receive suppliers and developers.

Since 2009, HRS has already delivered 39 refueling stations of 100 to 500 kg per day that are now in service across Europe and in the United States, including 37 stations in Europe.

Drawing on the experience it has gained over the last 18 years in engineering and complex industrial piping, as well as the integration and manufacturing of medium and high-capacity stations, since 2019, HRS has developed a new range of stations that can deliver 14 to 80 kg of hydrogen per hour. These developments are carried out in the Champ-Sur-Drac factory in the Grenoble region.
