Large-scale industrialization
SymphonHy (IATF 16949-certified) is our first Gigafactory and Europe's biggest production site for fuel cell stacks and systems. With an initial production capacity of 10,000 systems, rising to 20,000 systems per year by 2028, the site is a major milestone in rolling out our industrial roadmap. Our objective is to manufacture 200,000 systems per year worldwide beyond 2030, in order to support a quick time-to-market for our customers, and meet the growing demand for zero-emission hydrogen mobility.
An ambitious roadmap to meet the growing needs of the hydrogen mobility market
- 2021/ 2023: Pilot plant – 1,000 to 2,500 fuel cell systems/year
Our first production site, a laboratory for the development of our industrial scale-up processes. - 2024/ 2028: Ramp-up to large-scale production – from 10,000 to 20,000 systems/year
Launch of SymphonHy, Europe's largest production site for fuel cell stacks and systems, in Saint-Fons, France, in 2023.
1st expansion of our industrial footprint in the USA with the opening of our production site in Temecula, California, for the assembly of fuel cell-equipped heavy-duty vehicles. - Beyond 2030 ambition: 200,000 systems/year worldwide.
SymphonHy, Europe's largest integrated production site for fuel cell systems.
Our SymphonHy Gigafactory is Europe's biggest production sites for fuel cell stacks and systems. Meeting the highest automotive standards (IATF 16949-certified), SymphonHy brings together under the same roof our production capacities and our Research & Innovation center. In the emerging hydrogen market, where fuel cell production standards do not yet exist, our Gigafactory will help define these standards.
We have unprecedented measurement and analysis resources, with over 100 test benches. This latest-generation equipment was developed and installed with our partners, who are leaders in the construction of test, assembly and control systems for fuel cells, batteries and electrolyzers.
In line with our roadmap, we are exploring the possibility to build a second Gigafactory circa 2028.
HyMotive: a transformational project that accelerates Symbio's roadmap to become a world-class fuel cell player
SymphonHy is part of our seven-year, €1 billion investment plan through our HyMotive project. HyMotive is supported by the European Commission as part of the Hy2Tech IPCEI (important projects of common European interest) hydrogen program, and by the French Government (France 2030, France Relance). It aims to accelerate Symbio's industrialization and disruptive innovation, and will lead to the creation of 1,000 jobs. It will contribute to the construction of a solid hydrogen ecosystem in Europe, a key lever for achieving Europe's net-zero target.
In its second phase, HyMotive will develop and industrialize a new generation of innovative fuel cell systems, based on disruptive technology. This will boost the performance of Symbio's StackPack brand systems, while drastically reducing unit costs.


Expanding our industrial footprint in the USA with our Californian plant.
With the support of the California Energy Commission (CEC), Symbio is finalizing the construction of an industrial site in Temecula. Operational from 2024, the plant will assemble fuel cell-equipped heavy-duty vehicles (including trucks and commercial vehicles), as well as producing complete fuel cell systems.
The plant is a sign of CEC's renewed confidence, following its support for the “Symbio H2 Central Valley Express” project, which aims to demonstrate the advantages and reliability of hydrogen mobility for heavy-duty transport. Both projects aim to support California's goal of achieving carbon neutrality for its entire economy by 2045.
Innoplate, our joint venture with Schaeffler for the production of bipolar plates.
Symbio and the Schaeffler Group have set up the Innoplate joint venture to produce bipolar plates, a strategic component of fuel cells, Operational as of early 2024, the production unit is located in Haguenau (France). Its initial capacity reaches 4 million bipolar plates per year, rising to 50 million worldwide by 2030.
