Successful road tests System performance validated (TRL7) – Hopium reaches the final milestone before commercialization of the 100 kW hydrogen fuel cell system

Paris, October 7, 2024 at 6:00 p.m. – HOPIUM (FR0014000U63 – ALHPI), the cleantech company that aims to decarbonize heavy-duty transport, is pleased to announce the successful completion of its road tests, marking a decisive step towards the commercialization of its innovative fuel cell technology.

The road validation tests were carried out on the UTAC circuit and from the first laps, the fuel cell system demonstrated its robustness and allowed the test sessions to be carried out without interruption. The validation program included dynamic cycles on the road circuit (strong accelerations and decelerations, vibrations) and tests on the speed ring (high speed, thermal cycling, good and rainy weather), corresponding to the usage cycles of heavy-duty transport.

These tests confirm the robustness and reliability of the hydrogen propulsion system developed by Hopium. They thus validate the operation of the Hopium fuel cell system in a real environment, i.e. a TRL7 maturity level. This crucial milestone represents a significant step forward towards the company’s goal of offering a solution for the decarbonization of heavy-duty transportation.

Stéphane Rabatel, CEO of Hopium, said:

We are delighted to have reached this milestone. It is the result of several years of R&D but also of all the expertise and know-how of our teams since the beginning of Hopium. I would like to sincerely thank them and salute their work and their involvement because without them, none of this would have been possible ,


These tests validate not only the quality of our fuel cell technology, but also our commitment to decarbonized and responsible mobility. Many partners and customers have been waiting for this confirmation to go further with us. We are now on the verge of commercializing our system, which has enormous potential in many applications.

Following numerous discussions at the Hydrogen Business for Climate Forum on October 1 and 2, Hopium confirmed its development strategy, initially targeting niche markets, such as the K-Challenge maritime project, in order to finance the industrialization of its fuel cell system, which will enable it to reduce its manufacturing costs and offer a competitive alternative to diesel for the heavy-duty transport market by 2028-2030.

Hopium will devote the coming months to intensifying discussions with a view to acquiring a stake in its capital from a major industrial player to support its future developments, in particular the installation of its automated assembly line on its new site in Saint-Bonnet-de-Mure and the finalization of its 200 kW system, composed of two 100 kW fuel cells, in an industrial version intended for heavy-duty transport.

Hopium embodies the expertise and commitment to pushing the boundaries of sustainable mobility. With its advanced fuel cell system, the company offers a low-carbon alternative to diesel engines, meeting industry expectations as well as the needs of the heavy-duty transport sector, without compromising on performance and autonomy.
