BarMar Hydrogen Pipeline Enters Public Review in France
The BarMar hydrogen pipeline linking Spain and France has entered public consultation in France as developers advance a major European hydrogen corridor project.
(P&GJ) — Developers of the BarMar hydrogen pipeline have launched a public consultation process in France, advancing plans for a cross-border energy corridor designed to transport renewable hydrogen from the Iberian Peninsula into northwest Europe.
The consultation period runs from May 6 through July 12 and covers the French portion of the proposed subsea pipeline linking Barcelona, Spain, with Fos-sur-Mer in southern France.
BarMar is part of the broader H2med corridor, a European infrastructure initiative intended to connect hydrogen production centers in Portugal and Spain with industrial demand hubs in France and Germany. Project developers said the pipeline could transport up to 2 million metric tons of renewable hydrogen annually.
France’s National Commission for Public Debate (CNDP) is overseeing the consultation process, which includes public meetings, technical presentations and stakeholder discussions focused on routing, environmental impacts and project development plans.
Developers plan to hold 25 consultation events across southern France, including major meetings in Gruissan, Canet-en-Roussillon and Fos-sur-Mer.
The BarMar project has continued gaining regulatory and financial support across Europe. In 2025, transmission operators Enagás, NaTran and Teréga formed a joint venture to develop the pipeline and secured European Union funding for engineering and environmental studies.
Earlier this year, the European Union reaffirmed Project of Common Interest status for the BarMar and CelZa hydrogen interconnections, giving the projects access to streamlined permitting procedures and additional funding opportunities.
The corridor is expected to play a role in Europe’s broader decarbonization strategy, particularly for industrial sectors viewed as difficult to electrify. Developers estimate the H2med network could eventually supply about 10% of Europe’s hydrogen demand by 2030.
