RotH2 wins an order for 330 1000 bar hydrogen cylinders from Atawey
The tank manufacturer, based in Mions in the Lyon metropolitan area, announced on 10 November 2026 this order placed by Atawey, a Savoy-based specialist in hydrogen refuelling stations. The equipment will supply infrastructure dedicated to heavy-duty mobility that Atawey is deploying in Belgium.
Nine racks of Type II cylinders for heavy-duty mobility
The order covers 330 Type II cylinders of 50 litres each, designed for a pressure of 1000 bar. They are arranged in nine racks equipped with maintenance valves, assembled into units intended to supply hydrogen refuelling stations directly.
Type II cylinders consist of a steel liner reinforced with filament-wound composite. According to RotH2, for equal dimensions, they allow more gas to be stored and refuelling to be accelerated. Both companies are located in Auvergne-Rhône-Alpes, RotH2 in the Rhône department and Atawey in Savoie.
A volume greater than the racks delivered abroad this summer
This summer, RotH2 delivered a 22-cylinder rack of 1000 bar cylinders to the University of the Western Cape, in South Africa, as part of the HySA programme, as well as two 16-cylinder racks to ARPA, in Spain. With nine racks and 330 cylinders, Atawey's order represents a significantly larger volume.
Chief Executive Officer Quentin Marsac stated that this order "marks an important step in the development of RotH2" and that it "first and foremost confirms our technological and industrial choices in very high pressure". The company indicates that the challenge now lies in the gradual integration of these solutions by the industry.
A diversification into hydrogen launched in 2021
Historically present in the markets for underwater diving cylinders and accumulator bodies, RotH2 expanded its activity in 2021 into the storage of green gases, including hydrogen, while retaining its historical customers. This development was accompanied by industrial investments, notably in a filament-winding machine.
These investments enabled the company to become, at the end of 2023, according to itself, the first French company to manufacture Type II cylinders certified up to 1000 bar. Its plant produces 20,000 steel cylinders per year and employs 50 people. RotH2 will publish its 2026/27 half-year results on 16 December 2026, after market close.
