Energy Sovereignty: French hydrogen infrastructure projects by NaTran and Teréga recognized as being of major European importance

The publication in the Official Journal of the European Union of the delegated act establishing the new list of Projects of Common Interest (PCI) marks a historic turning point for French energy infrastructures. By labeling a series of French projects, Europe confirms that France will be at the heart of the future continental hydrogen backbone.

A breakthrough for regional projects, including the HySoW project.

This new list partially renews the status of key cross-border infrastructures, such as the Spanish backbone and the BarMar (Barcelona-Marseille) and CelZa (Celorico da Beira - Zamora) interconnectors, which are components of the H2med corridor, while officially integrating several major French projects led by NaTran and Teréga into the European network:

  • The HY-FEN project: this strategic national artery, approximately 1000 km long and led by NaTran, connects the Mediterranean (in direct extension of the BarMar project) to the major consumption hubs in Northern and Eastern France, opening the way towards Germany. HY-FEN meets the needs of our regions and transforms France into an indispensable energy bridge between the Iberian renewable hydrogen production basins, storage sites, and European industrial centers.

  • The MidHY project (led by NaTran), with a length of 200 km, is an essential interconnector link to connect the regional HySoW network to the HY-FEN backbone.

  • The HySoW project, Hydrogen South-West, led by Teréga, asserts itself as a pillar of the Grand Sud-Ouest (Great South-West) and an essential link in European energy sovereignty. Its transport network of over 650 km connects the production, import, and consumption zones of South-West France to the European H2med corridor. It is complemented by an underground hydrogen storage facility which, with a capacity of 500 GWh PCS, guarantees system flexibility, secures supply, and enables the absorption of variations in hydrogen production and demand.

  • The MosaHyc, RHYn, Hy4Link projects, and the Franco-Belgian corridor, led by NaTran, link HY-FEN to the industrial basins of Eastern France and Central Europe (Germany, Luxembourg, Belgium).
