AquaDuctus Pipeline to Transport Green Hydrogen from North Sea to Land

GASCADE, Gasunie, RWE and Shell are progressing with the AquaDuctus pipeline project, which will transport green hydrogen from the North Sea directly to the continent, according to a news release.

The companies "signed a declaration of intent to further intensify their collaboration" on the project, RWE announced Monday.

The AquaDuctus pipeline is the vision for the first German offshore hydrogen pipeline. The pipeline is part of the AquaVentus initiative, which plans to install 10 gigawatts of electrolysis capacity for green hydrogen production from offshore wind power between Heligoland and the Dogger sand bank. In the dovetailed sub-projects, demand, generation and transport of hydrogen are to be synchronized in order to enable a swift market ramp-up.

Once the construction of the generation plants is fully completed, AquaDuctus would transport up to one million tons of green hydrogen annually from 2035 onwards, thus making a substantial contribution towards the decarbonization of energy supply in Germany and Europe.

Compared to the transport of electricity generated offshore, the pipeline offers economic advantages. The pipeline will replace five High Voltage Direct Current (HVDC) transmission systems, which would otherwise have to be built. It is a cost-effective option for transporting large volumes of energy over distances of more than 400 kilometers.

The first step in the AquaDuctus project is to carry out a detailed feasibility study. AquaDuctus has also participated in the IPCEI (Important Project of Common European Interest) process of the German Federal Ministry for Economic Affairs and Energy.
