This is a key moment for Europe’s energy future. And one of the protagonists is H2med, the great green hydrogen corridor that will connect the Iberian Peninsula with the industrial heart of the continent.
In this article, we take a closer look at what milestones have been achieved so far and why H2med is becoming the linchpin of Europe’s future hydrogen economy.
H2med is the first European green hydrogen corridor designed to transport green hydrogen produced in the Iberian Peninsula to the main consumption centres in Northern Europe. It is being driven by Enagás together with the TSOs of France (Térega and NaTran), Portugal (REN) and Germany (OGE) and is scheduled for commissioning in 2032.
Its main objective is to connect Iberian production – powered by solar and wind energy potential – with the major European industrial centres that will need renewable hydrogen to decarbonise sectors that are difficult to electrify, such as steel, cement and fertilisers.
H2med will have the capacity to transport up to 2 million tonnes of renewable hydrogen per year
H2med includes these two infrastructures:
According to the latest estimates, H2med will have the capacity to transport up to 2 million tonnes of renewable hydrogen per year, equivalent to 10% of the EU’s total green hydrogen consumption target for the early 2030s.
This year has been a turning point. In order to identify infrastructure needs linked to hydrogen development in Europe, the project partners launched a Call for Interest process – a non-binding expression of interest – aimed at all actors in the hydrogen value chain at the end of 2024. The results of this call were presented to the industry on 10 February 2025, after receiving responses from around 170 companies and more than 500 projects, a clear sign of the strong market interest and the central role the corridor will play in the European decarbonisation objectives.
Enagás – through its subsidiary Enagás Infraestructuras de Hidrógeno (EIH) – NaTran and Térega (France) set up the company in charge of designing, building and operating BarMar, the H2med section that will connect Spain with France. This joint venture marks a decisive technical and financial step, as it establishes a clear framework of responsibilities, financing and implementation.
BarMar will link the port of Barcelona and reach the Marseilles area, allowing a bi-directional flow and ensuring compatibility with future national hydrogen networks.
BarMar will be a 400 km-long infrastructure with a planned transport capacity of 2 million tonnes per year
A few weeks ago, the European H2med corridor project reached a key milestone with the successful completion of the first in-depth assessment of the BarMar undersea route. This analysis, carried out by geophysical survey specialists during the summers of 2024 and 2025, confirms that the proposed route for the hydro-product is fully feasible from an engineering point of view.
H2med was declared a Project of Common Interest (PCI) by the European Commission in 2024, and in 2025 has obtained more than 35 million euros of European funds from the Connecting Europe Facility (CEF), to fund studies of the key infrastructures of the corridor, CelZa and BarMar, as well as the national networks of Spain, Portugal and France.
Specifically, a total of 28,336,978 euros of the grant will allow the H2med-BarMar consortium to partially finance the engineering studies, including marine and environmental reconnaissance campaigns, while the H2Med-CelZa project has been allocated a total of 7,221,872 euros of the grant, which will be used to execute the basic and detailed engineering phases of the pipeline and the compressor station.
The H2med Alliance, the industrial collaboration network that brings together companies, technology centres and developers involved in the hydrogen value chain – from renewables producers and electrolyser manufacturers to logistics operators and large industrial consumers – has also grown significantly during 2025.
The initiative recently incorporated 40 new members from across the hydrogen value chain, including companies such as Repsol, BP, EnBW, INEOS and EDP Renováveis, bringing the total number of participating entities to 49.
The H2med Alliance’s commitment is in line with the common economic agenda of the President of the French Republic, Emmanuel Macron, and the Chancellor of the Federal Republic of Germany, Friedrich Merz, who reaffirmed their commitment to the timely implementation of the H2med corridor.
Europe needs green hydrogen to meet its climate targets. But it also needs to diversify its energy sources and reduce its dependence on imported fossil gas. The H2med hydrogen corridor offers a strategic solution to both needs:
H2med plans to start operating in 2032, with an associated network of more than 200 linked hydrogen projects on the Iberian Peninsula
2025 was undoubtedly the year in which H2med put all its chips on the table. With technical feasibility confirmed, EU funding secured, an operational consortium in place and growing demand along the entire value chain, H2med is moving towards its goal: to become the great renewable hydrogen highway in Europe and to make hydrogen one of the decisive vectors for the continent’s decarbonisation and industrial competitiveness.
