AquaDuctus –
Transport pipeline for green hydrogen from the North Sea

In the future the offshore AquaDuctus pipeline will transport green hydrogen from the North Sea directly to the mainland. It is part of the AquaVentus initiative, which plans to install 10 gigawatts of electrolysis capacity for hydrogen production from offshore wind power between Helgoland and Doggerbank.

The AquaDuctus pipeline is the vision for the first German offshore hydrogen pipeline. Once the construction of the production plants is fully completed, AquaDuctus shall transport up to one million tonnes of green hydrogen annually from 2035 onwards, thus contributing towards the decarbonization of energy supply in Germany and Europe. AquaDuctus is therefore a key milestone in the implementation of the German and European hydrogen strategies. GASCADE, Gasunie, RWE, Equinor and Shell are involved in the project.

Compared to the transport of electricity generated offshore, the pipeline offers clear economic advantages. AquaDuctus will replace five high voltage direct current (HVDC) transmission systems, which would otherwise have to be built. It is by far the most cost-effective option for transporting the 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.
