In the Aude region, Eiffage Génie Civil is constructing what will become France's largest renewable hydrogen facility.

In Port-la-Nouvelle, our teams are carrying out the civil engineering works for HydOcc, the future largest renewable hydrogen facility in France!

In the Aude region, Eiffage Génie Civil is constructing what will become France's largest renewable hydrogen facility.

For this project, nearly 10 months of work will be required, with 5,000 m³ of concrete to be poured on site, 4,650 m² of fireproof walls, 5 meters high, to be installed, and 50 workers to be mobilized at peak times.

This new facility will produce hydrogen through water electrolysis, powered by green electricity, with an output of 2,800 tons per year (20 MW in the first phase)!

The production unit will supply heavy transportation in the region (maritime, land, river, and rail), positioning the area as a key player in the energy transition by preventing the emission of 28,000 tons of CO₂ equivalent per year.

Consortium: Eiffage Génie Civil (lead contractor) / Razel-Bec Roussillon for Hyd'Occ (Qair France - Qair Group and AREC Occitanie).
