MW
Capacity (1st phase)
Hyd’Occ is France’s largest renewable hydrogen production unit, and is operated by Qair in Port-La Nouvelle. The first molecule was produced at the end of 2025 and the full commissioning of the first 20 MW phase is scheduled in 2026.

Annual production of renewable hydrogen (1st phase)
Hydrogen will be produced by low-temperature, low-pressure, alkaline electrolysis of water, mainly for maritime and mobility uses and will be delivered by container via the multimodal logistics hub of Port-La Nouvelle.
Qair is proud to work with AREC Occitanie, the energy transition agency of Occitania, to bring the Hyd’Occ project to life. This initiative is part of the region’s ambitious to become Europe’s leading positive energy region by 2050.
Hyd’Occ is a winner of the French call for projects “Corridor H2”, a Europe-wide initiative that aims to develop a series of hydrogen production and distribution capacities for mobility from the Iberian Peninsula to Northern Europe, coupled with the deployment of numerous heavy vehicles using hydrogen. This initiative is led by the Occitanie Region and backed by the European Investment Bank, and the European Commission.
From the outset, our teams have worked closely with local stakeholders, enabling everyone from elected officials to industrial companies to join forces and lend their support to the project. Hyd’Occ is set to trigger a virtuous energy cycle, whereby local renewables are used to create hydrogen, heat and oxygen in order to promote the carbon-free development of Occitania.
