Spanish and French Gas Grid Operators Launch JV to Build Underwater H2Med Hydrogen Pipeline

by | Jul 11, 2025

Spanish and French gas grid operators have formed a joint venture (JV) to develop the critical underwater BarMar section of the H2Med hydrogen pipeline network, a strategic link for Europe’s clean energy future.

Enagás (Spain), NaTran (France), and Teréga (France) have partnered to build this Project of Common Interest (PCI), connecting Barcelona to Marseille. The BarMar pipeline will form part of the 5,500 km H2Med corridor, designed to deliver 2 million tonnes per year of renewable hydrogen by 2030, strengthening Europe’s energy independence and decarbonisation goals.

 

The underwater pipeline, known as BarMar, will transport green hydrogen produced in the Iberian Peninsula to European markets via France, facilitating industrial decarbonisation, hydrogen mobility, and energy security.

Spanish and French gas grid operators have formed a joint venture (JV) to develop the critical underwater BarMar section of the H2Med hydrogen pipeline network, a strategic link for Europe’s clean energy future.

Key Highlights:

  • JV Partners: Enagás, NaTran, Teréga
  • Pipeline: BarMar (Barcelona to Marseille)
  • Network: Part of H2Med, 5,500 km hydrogen corridor
  • Capacity: 2 million tonnes per year (H2Med total)
  • Timeline: Operational by 2030
  • Impact: Strategic PCI to reduce EU dependence on Russian gas, enabling renewable hydrogen flows.

 

Teréga President Dominique Mockly stated that this JV “will make hydrogen corridors between Spain, France, and Europe a reality,” positioning the Iberian Peninsula as a leading green hydrogen export hub.

 

The BarMar section is central to EU decarbonisation plans, receiving PCI status and significant backing under REPowerEU. Final investment decisions are expected in 2026, with construction commencing shortly after.
