RWE, Shell, Gasunie and Equinor have signed a declaration of intent to further intensify their collaboration on the AquaSector project - the vision of the first large-scale German offshore hydrogen park.

The AquaSector project intends to install approx. 300 MW electrolyser capacity to produce up to 20,000 tons per year of green hydrogen offshore. The green hydrogen is planned to be transported via a pipeline, called AquaDuctus, to Heligoland starting in the year of 2028.

The partners see the AquaSector project also as a ‘proof of concept‘ for the realisation of the AquaVentus vision of producing up to 10 GW of green hydrogen offshore by 2035 and transporting it via an extended pipeline to mainland Germany.

According to the project partners, compared to the transport of electricity generated offshore, the hydrogen production at sea and the transport via pipeline could offer clear economic advantages. They anticipate the pipeline could replace five High Voltage Direct Current (HVDC) transmission systems, which would otherwise have to be built.

The first step in the AquaSector project for the partners is to carry out a detailed feasibility study. The study will provide important initial indications of the conditions under which the large-scale offshore hydrogen park can be realised as well as the technical and commercial challenges which need to be overcome in regards to offshore hydrogen production.
