FEV News


FEV, an internationally recognized innovation leader across different sectors and industries, showcases its innovative portfolio for the highly demanded decarbonization of industry and transportation at Hyvolution in Paris on February 1st and 2nd. With a focus on the company’s retrofit solution, FEV presents its latest developments, dedicated to the entire hydrogen value chain.


Innovations developed by FEV
On the way to the desired energy transition, hydrogen will play an essential role. FEV currently develops two different technology approaches to use hydrogen as a mobility energy source: Beside the concept of Fuel-Cell Electric Vehicles (FCEV) hydrogen internal combustion engines (H2 ICE) extend the possible H2-application fields. For long-distance road applications, like medium and heavy-duty trucks or coaches as well as for railway and maritime transport, hydrogen is a promising alternative, that is already in use for several years.

Retrofitting accelerates the ecological transition: Partnership with NGV Powertrain
Retrofitting involves replacing a traditional powertrain with a more environmentally friendly one. The main advantage of the H2 ICE is the option to replace a diesel or petrol fired combustion engine at comparably low efforts with a power unit that is in line with climate concerns.

At Hyvolution, FEV and NGV Powertrain, an Italian startup with a focus on the development of alternative propulsion systems will present a jointly developed nine-liter engine, which has been converted to hydrogen operation. Currently, this type of engine is mainly used for road transport, as well as in the construction and maritime sectors. As such, the companies’ offer of a retrofit solution will be of great interest to enterprises owning fleets of buses or trucks. For this project, FEV works on design and software aspects at its French location in Saint-Quentin-en-Yvelines. The engine shop, finetuning and testing take place at Saint-Etienne-du-Rouvray.

Advantages of this development:
  • Like a fuel cell or a battery solution, the hydrogen engine does not emit CO2, since hydrogen molecules don’t contain carbon
  • Reduced NOx emissions
  • With retrofitting, it is possible to retain the existing vehicle fleet while making it greener
FEV France is one of eight successful candidates in the automotive sector that have been selected as part of the France Relance Plan initiated by the French government. Since then, FEV has invested in three test benches on its site at Saint-Etienne-du-Rouvray (Seine Maritime): two test benches for hydrogen internal combustion engines and one fuel-cell test bench with a capacity of up to 240 kW.
