German transmission system operator Gascade Gastransport and UK-based National Gas have signed a memorandum of understanding to build an offshore hydrogen pipeline between the two countries. The proposed hydrogen corridor will run through the North Sea and connect to offshore wind farms. The pipeline is designed to offer bidirectional transport capacity, providing greater flexibility and security of supply for both markets by linking the UK’s renewable energy resources with Germany’s future hydrogen storage and consumption infrastructure.
The two companies aim to obtain Project of Common Interest (PCI) or Project of Mutual Interest (PMI) status for the initiative. They also plan to include the project in the European Union’s Ten-Year Network Development Plan (TYNDP) 2026.
The project builds on a feasibility study conducted by Arup, Adelphi and the German Energy Agency (Dena) as part of the UK-Germany Hydrogen Partnership. The study confirmed the viability of such a corridor to accelerate the development of a cross-border hydrogen market.
The UK-Germany Hydrogen Corridor is to consist of two offshore pipeline sections. The first segment will start on the British mainland and connect to the second segment – Gascade’s AquaDuctus pipeline project, which links to the German mainland.
