AquaSummit 2026
Three days of offshore hydrogen on the North Sea island of Helgoland – presentations, general assembly, networking and nature experiences.
From 16 to 18 September 2026, the AquaVentus community gathered for the second AquaSummit on the North Sea island of Heligoland. Around 80 experts from industry, research and policy spent three days discussing the future of offshore hydrogen – from project updates on AquaPrimus and AquaDuctus to scientific workshops with the North Sea Energy Programme and SOffie, as well as the members’ assembly. Alongside the professional programme, bunker tours, a dune excursion and the joint AquaDinner provided unforgettable impressions on Heligoland.

Summit Themes
Offshore System Integration
SOffie and NSE6 – two international research projects with over 40 partners – explored how offshore wind, hydrogen and CO₂ can be integrated into a climate-neutral North Sea energy system.
Project Updates
AquaPrimus, AquaDuctus and offshore scaling studies: members presented concrete progress – from initial 30 MW plants to long-term pipeline infrastructure in the North Sea.
Standards & Safety
The standards working group addressed fire and explosion protection, evacuation concepts and certification for offshore electrolysis platforms – key issues on the path to market readiness.
