New contracts

Elogen is selected by Symbio to supply an electrolyser with an initial capacity of 2.5 MW for its new fuel cell plant

Les Ulis/Vénissieux, 21 July 2022 – Elogen, leader in PEM[1] electrolysis, and Symbio, a joint venture between Faurecia and Michelin, which designs, produces and markets systems for hydrogen mobility, announce the signing of a contract for the supply by Elogen of a PEM electrolyser with an initial capacity of 2.5 MW for Symbio’s new fuel cell plant.

Located in Saint-Fons near Lyon, in the heart of the Vallée de la Chimie, Symbio’s first gigafactory will be one of the largest manufacturing sites for hydrogen fuel cell systems in Europe with an eventual total production capacity of 50,000 systems per year. This flagship, called SymphonHy, will also house the Group’s head office, its R&D center, the Symbio Hydrogen Academy and an incubator for start-ups around decarbonized hydrogen.

SymphonHy will be a center of environmental excellence, certified “BREEAM[2] Very Good” from the start thanks to high energy efficiency levels of its buildings and processes, its energy self-sufficiency, as well as the use of renewable energies and green hydrogen.

The Elogen electrolyser will produce part of the hydrogen volumes that Symbio will need, in particular to test and activate its fuel cell systems at the end of the manufacturing process. It will be designed in a modular way, allowing Symbio to produce one tonne per day of low-carbon hydrogen.

The electrolyser will be delivered by Elogen to the Saint-Fons site during the fourth quarter of 2023, in line with the launch of production.


Philippe Rosier, CEO of Symbio, comments: « With this electrolyser in situ at our Saint-Fons gigafactory, Symbio will be able to recycle the water and electricity resulting from its own production by producing part of its green hydrogen needs. Symbio believes in the principles of the circular economy of which this project is a part and constitutes a first step, in line with our strategy and our vision for a more positive future. Furthermore, this announcement is a new testimony to the dynamism of the hydrogen value chain in which our Group is delighted to actively participate. »

Jean-Baptiste Choimet, Managing Director of Elogen, comments: « We are delighted with the signing of this contract with Symbio, a world leader in hydrogen mobility and technological partner of Elogen within the framework of the hydrogen IPCEI[3]. Symbio’s choice of the Elogen solution for its future high-tech plant in Saint-Fons confirms the relevance and attractiveness of the PEM technology developed by Elogen to produce green hydrogen in a modular and flexible way. This new contract also represents an important step for Elogen since it highlights our ability to deploy our technology on several megawatts in the service of major industrial projects. »
