The AquaDuctus hydrogen pipeline planned by GASCADE and Fluxys in the North Sea has today received state aid approval from the European Commission under the IPCEI hydrogen framework. The first AquaDuctus project section, which has now been notified as an IPCEI, provides for the construction of an offshore pipeline approximately 200 kilometers long and an onshore pipeline approximately 100 kilometers long, the transport capacities of which are to be available for the SEN-1 hydrogen wind farm in particular from 2030.In order to meet the goal of creating a demand-oriented hydrogen infrastructure for north-western Europe, the entire German Exclusive Economic Zone is to be developed with the second offshore project section, which is also around 200 kilometers long.
