Pipeline with a capacity of 2 million tonnes per year will supply hydrogen between Barcelona and Marseille under the Mediterranean Sea

A pipeline corridor to supply hydrogen has been announced to supply green hydrogen from the Iberian Peninsula to the rest of Europe. According to a report by France 24, the initiative was announced by the leader of France, Spain and Portugal on Friday, December 9.  

Spanish Prime Minister Pedro Sanchez during a joint press conference with French President Emmanuel Macron and Portuguese Prime Minister Antonio Costa said, the project known as BarMar, will cost around €2.5 billion. 

“It is going to be the first major hydrogen corridor in the European Union,” said Sanchez, according to a quote in the report. Sanchez further added, “The pipeline between Barcelona and Marseille will have a capacity of 2 million tonnes a year, or 10% of European consumption and will be ready by the end of the decade”.  

Plans are also for an additional pipeline connecting Spain and Portugal worth over € 350 million euros.  

The name for the entire project between the three countries is being called H2MED and it comes at a time when Europe is struggling with high energy costs after the Ukraine war. 

The plans for the proposal were signed by the three leaders in the presence of EU Commission chief Ursula Von der Leyen. Discussing the project, Leyen said, “The corridor will make Iberia a major energy hub and form part of a European hydrogen backbone allowing the bloc to pump hydrogen across the continent as it seeks to produce 10 million tonnes of clean hydrogen a year and import a further 10 million tonnes by 2030”.  

The leaders came together for this meeting on the sidelines of the EuroMed 9 summit, which is an alliance of nine Mediterranean and Southern European Union member states.
