The H2med project has launched a Call for Interest to assess the needs of infrastructure users across the hydrogen value chain until December 18th. This initiative aims to optimize infrastructure design and operational requirements. The project, spanning Portugal, Spain, France, and Germany, focuses on interconnecting hydrogen networks from the Iberian Peninsula to Northwestern Europe to enable a hydrogen economy by 2030 and support Europe's decarbonisation goals. Key projects like CelZa and BarMar, with significant capacities for hydrogen transportation, have been included in the Projects of Common Interest list, showcasing their contributions to sustainability, market integration, and competitiveness at the European level. The collaboration between these countries highlights Southern Europe's strategic role in competitive hydrogen production. The development of the H2med Corridor will cover the entire hydrogen value chain, enhancing economic competitiveness for industrial users, promoting carbon savings, and fostering the growth of new industries. The initiative aims to position clean hydrogen as a central element of the future energy system, aligning with the EU's goals for hydrogen market development and decarbonisation.
