BarMar: Green Hydrogen Link Between Spain and France

BarMar is a 400 km offshore pipeline project that will connect Barcelona (Spain) to the industrial hub of Fos-sur-Mer, near Marseille (France). The aim of this project is to create a major corridor for exporting hydrogen produced in Portugal and Spain from renewable energy sources (essentially solar and wind) at competitive costs, to the French hydrogen backbone—connected in turn to hydrogen infrastructure being developed in Germany and the rest of northwest Europe.

The BarMar project is part of the European Union’s ambition to become the world’s first climate-neutral continent, as outlined in the European Green Deal adopted in January 2020. This policy targets a 55% reduction in net greenhouse gas emissions by 2030 while maintaining industrial competitiveness.
Renewable hydrogen plays a central role in this transition as a key energy carrier.
The BarMar project aims to establish a pipeline for importing decarbonised hydrogen from the Iberian Peninsula to France, contributing to the competitiveness of green energy imports.

BarMar will have a transmission capacity of 2 million tonnes of hydrogen per year (MTPA). This strategic project aims to connect three key regions in the energy transition:

• Iberian Peninsula:
  Portugal and Spain are significantly increasing their renewable energy production capacities (solar and wind) and plan to export over 1.6 million tonnes of hydrogen annually by 2030,reaching full BarMar capacity as of 2032, according to the results of the Call for interest launched in November 2024
• France:
  France aims to develop national hydrogen transport network . BarMar will connect four major branches of this network: HY-FEN, HYnframed, MidHY, and HySoW.
• Germany:
  The decarbonisation of German industry is a European priority. Germany could import 1 million tonnes of hydrogen per year by 2035, and up to 1.6 million tonnes by 2040.
