AquaDuctus Hydrogen Pipeline

From Global Energy Monitor
This article is part of the Global Fossil Infrastructure Tracker, a project of Global Energy Monitor.

AquaDuctus Hydrogen Pipeline is a proposed offshore hydrogen pipeline that will connect the UK and Germany to an offshore hydrogen production facility.[1]


The pipeline will run from a future offshore green hydrogen production facility between Germany and UK to Helgoland, Germany and the Dogger Sand Bank, UK.[2]

The AquaDuctus Hydrogen Pipeline is part of the green hydrogen infrastructure mega-project "AquaVentus". This broad project covers a range of smaller projects that aim to produce and transport up to 10 GW of green hydrogen to Europe. The project involves using offshore wind-farms in the North Sea to power electrolysers, which will then produce Hydrogen that can be used for power generation once it is transported through pipelines.[1]

More than 40 partner organizations are involved in the AquaVentus project.[6]

According to ENTSOG's December 2022 TYNDP project list breaks down the project into the following 3 phases:[7]

Phase 1 (Heligoland–Aquaprimus II)

In this phase, a 28 MW electrolyser is expected to be built at the AquaPrimus site, which will then be connected to Heligoland, Germany.

Phase 2 (Extension of Phase 1 to AquaSector production sites)

The AquaSector wind farm is a proposed wind farm 150km north of Heligoland, with a potential maximum capacity of 300 MW. The second phase of the AquaDuctus pipeline will link the first phase to the AquaSector hydrogen production sites.

Phase 3 (Connection to German mainland)

The final phase involves the connection of the AquaDuctus to the German mainland, where the Hydrogen can be transported into Europe.
