The H2med project Supplying Europe with affordable carbon-free energy

The H2med project is a transnational initiative to interconnect the hydrogen networks of the Iberian Peninsula to Northwest Europe, enabling Europe to be supplied with affordable green hydrogen by 2030. This initiative was launched by France, Spain and Portugal, with a strong support by Germany, and is promoted by the TSOs of these countries: Enagás, GRTgaz, OGE, REN, and Teréga.

On the 20th of October 2022, alongside the Council of the European Union, the President of the Government of Spain, the President of the French Republic and the Prime Minister of Portugal decided to accelerate the development of energy interconnections and to create a green energy corridor connecting Portugal, Spain and France with the European energy network. They also agreed on the conclusion of a hydrogen interconnection between Portugal and Spain (Celorico da Beira – Zamora) as well as the development of a maritime pipeline connecting Spain and France (Barcelona – Marseille) in order to transport renewable hydrogen from the Iberian Peninsula to North and Central Europe. The three leaders ratified this commitment in the Euromed Summit on December 9th, 2022, in Alicante, with the support of the President of the European Commission Ursula von der Leyen.

Building on this political commitment, Enagás, GRTgaz, REN and Teréga have been cooperating since the 20th of October 2022 to provide technical advice to their respective governments related to the development of H2med. The four infrastructure operators signed a Memorandum of Understanding (MoU) to formalise their commitment to collaborate on the joint development of H2med, following the mandate of the Governments of the three countries given at the Euromed Summit. The objective of this partnership is to make the infrastructure available as of 2030. On December 15th, 2022, the four transmission system operators also jointly submitted the H2med project as candidate for the Project of Common Interest (PCI) under the new regulation on Trans-European Energy Network (TEN-E).

On January 2023, Germany has decided to lend its support and join France, Spain, Portugal for this hydrogen corridor. “We have decided to expand the H2med project which, with the support of European funding, will connect Portugal, Spain, and France to Germany, which will be a partner in this hydrogen infrastructure strategy,” declared the French President Emmanuel Macron during a joint press conference  with German Chancellor Olaf Scholz, on the occasion of the 60th anniversary of the reconciliation treaty between Paris and Berlin. 

On October 18th, 2023, the German TSO OGE joined the H2med project during the presentation of the corridor in Berlin. OGE’s involvement in the H2med initiative stresses the vital importance for Germany of a reliable hydrogen import corridor.

On the 8th of April 2024, the list of Projects of Common Interest (PCI) / Projects of Mutual Interest (PMI) was officially published in the Official Journal of the European Union, which includes the H2med project.

The corridor can transport 10% of expected hydrogen consumption in Europe by 2030

CelZa: linking Portugal and Spain with green hydrogen

CelZa is a 248 km pipeline project joining Portugal and Spain, connecting Celorico da Beira (Portugal) to Zamora (Spain). It will be a bridge between the developing core hydrogen backbones of both countries. Each of the two TSOs involved, REN and Enagás, will fully own their section of the infrastructure: 162 km in Portugal, 86 km in Spain.

CelZa will be a 100% hydrogen transmission infrastructure that will be the prime export medium for hydrogen produced in Portugal from renewable energy sources, most notably solar and wind.

BarMar: linking Spain and France with green hydrogen

BarMar is a 450 km offshore hydrogen pipeline project that will join Barcelona (Spain) to the industrial hub in Fos-sur-Mer, near Marseille (France). The project will be a major connection to export hydrogen produced in Portugal and Spain from renewable sources (essentially solar and wind) at competitive costs, to the French hydrogen backbone itself connecting to the developing hydrogen infrastructure in Germany and the rest of Northwest Europe.
