A statement by GASCADE said the first step in work on the AuquaDuctus project would be to conduct a detailed study on its technical and financial feasibility.
The AquaDuctus pipeline is part of the Aqua Ventus initiative, which plans to install 10 GW of electrolysis capacity for green hydrogen production from offshore wind power between Heligoland, Germany, and the Dogger sand bank off the east coast of England.
From 2035, the pipeline will be able to transport up to 1 million tonnes of hydrogen in a year.
The pipeline will replace five high voltage direct current (HVDC) transmission systems, which would otherwise have to be built. It is by far one of the most cost-effective options for transporting large volumes of energy over distances of more than 400 km.
