H2med project

Linking the coming hydrogen networks of the Iberian peninsula with those of northern Europe: this is the aim of the ambitious H2med infrastructure project jointly led by France, Spain and Portugal, with Germany’s support. By 2030, the project, in which Teréga is one of the main actors, aims to link the competitively-priced hydrogen production centres in Portugal and Spain, which will rely chiefly on solar power, to the major consumption areas of Northwestern Europe, while serving the whole nation’s needs alongside domestic production.

At the European Council on 20 October 2022, the French, Spanish and Portuguese Heads of State and Government announced their intention to create a “green energy corridor” linking the three countries to the European energy grid. That commitment was ratified on 9 December 2022 at the Euromed Summit in Alicante. A memorandum of understanding was then signed by four transport grid managers (GRTs): France’s Teréga and GRTgaz, Portugal’s REN, and Spain’s Enagás. In December 2022, the four operators submitted the H2med project for the list of projects of common interest (PCIs). They were joined in October 2023 by the main German grid manager, OGE, thus confirming Germany's interest in the H2med project.

Since 8 April 2024, H2med has been officially recognised as a European project of common interest.

The H2med project has two strategic segments: one segment which will link the hydrogen networks of Portugal and Spain (CelZa project), and an underwater infrastructure which will link Barcelona with the port of Marseille (BarMar project). 

The BarMar project will be connected in the west to HySoW, a 600 km hydrogen infrastructure developed by Teréga, which will supply the industrial centres of Bordeaux, Toulouse and Lacq, as well as the Nouvelle-Aquitaine underground storage areas and the ports of Bayonne and Port-la-Nouvelle.

Situated where the hydrogen networks of southern and northern Europe meet, BarMar will allow 2 million tonnes of hydrogen to be transported per year, which is 10%* of expected European hydrogen consumption by 2030.

It is also a real industrial challenge, with about 450 km of pipeline to be laid on the Mediterranean seabed, at a depth of up to 2600 m.

The H2med project has received the support of the European Commission, which incorporated it in November 2023 into the delegated act with the list of projects of common interest (PCIs) and projects of mutual interest (PMIs), finally adopted in the second quarter of 2024. These infrastructure projects are seen as a priority for interconnecting the energy networks of European Union countries; they benefit from fast-track authorisation procedures (simplified regulatory and permit procedures), but they also attract particular attention on the part of investors and future customers of those infrastructures.

Projects included in the list of PICs will benefit in particular from a simplification of the procedures for awarding permits, and more efficient environmental assessment. This important stage will also allow the BarMar and CelZa projects to qualify for financial assistance and be included in the next European call for funding (2024 Energy CEF call), the aim here being to provide financial backing for the studies required to trigger the investment decisions planned for 2026 and to meet the commissioning deadlines set for 2030. 

Preliminary studies for the project have already begun, including an assessment of the different possible corridors. Social and environmental impact studies have also been launched.

The final decision on investment will be taken at the end of 2026, and the target date for H2med to be operational is 2030. As part of the European Green Deal, the EU set out its road map for achieving carbon neutrality by 2050. The energy transition is at the heart of that ambition, and BarMar, as a key element of H2med, will make a major contribution to achieving it.

Since December 2022, the H2med project has made constant progress. The preliminary project studies and the assessment of alternative routes, aimed at allowing selection of the BarMar project corridor with the smallest impact, are under way. The social context and environmental studies are also being finalised.

Those studies were launched in February 2024 by the three partners behind the BarMar project, namely Enagás, GRTgaz and Teréga, in coordination with OGE
