  • Liebherr is developing air management technology that is particularly well suited to hydrogen fuel cells.

  • Alstom's hydrogen strategy is part of its ambition to innovate by pioneering smarter and greener mobility solutions for all.

29 November 2021 – Alstom has signed a collaboration agreement[1] with Liebherr – Aerospace & Transportation SAS, a France-based company specialising in the manufacture of compressors for fuel cells. This agreement is aimed at optimising hydrogen systems, including improving the reliability and durability of fuel cells, increasing their power density and reducing the cost of such solutions.


“Our ambition is to accelerate the adoption of hydrogen in the rail industry and to develop innovative solutions in the context of the greening of heavy mobility, including regional trains, shunting locomotives and freight locomotives.”

Jean-Baptiste Eyméoud
President of Alstom France

“Alstom has made sustainable mobility one of the pillars of its strategic plan Alstom in Motion 2025. Our ambition is to accelerate the adoption of hydrogen in the rail industry and to develop innovative solutions in the context of the greening of heavy mobility, including regional trains, shunting locomotives and freight locomotives,” said Jean-Baptiste Eyméoud, President of Alstom France, adding: “To develop a hydrogen ecosystem, particularly in France, we need to mobilise the public authorities and all the players in this sector. As in many fields, we are innovating with structuring partnerships: SNAM, Plastic Omnium, Hynamics, Eversholt and now Liebherr”.

Following the acquisition last April of Helion Hydrogen Power (an innovation start-up specialising in high-powered fuel cells, based in Aix-en-Provence), Alstom has now chosen to collaborate with the Liebherr group, which has a strong presence in the South-West of France.

Leveraging its extensive experience in fuel cell technology for automotive and aerospace applications, Liebherr, as a supplier of turbochargers to fuel cell system integrators, will play a major role in the process of reducing emissions from rail transport.

This collaboration between Alstom and Liebherr is an additional asset in the development of Alstom's hydrogen business, which relies, among others, on Alstom's site in Tarbes (in eth South-West of France), a global Centre of Excellence for “green” traction systems, and on Alstom Hydrogène site in Aix-en-Provence, which covers the entire high-power fuel cell value chain and focuses mainly on the energy and transport markets, in France and internationally.

In addition, Alstom signed an agreement with Snam[2] (Italy's leading natural gas transport company) in 2020 to develop hydrogen trains and associated infrastructure. Alstom will be responsible for the production and maintenance of the hydrogen trains (new or retrofitted), while Snam will develop the infrastructure for the production, transport and refuelling of these trains.

Alstom also announced last month that it had signed a memorandum of understanding with Plastic Omnium, a major player in hydrogen mobility, for the development of high-end hydrogen storage systems for the rail sector.
