AquaCore: Direct usage hydrogen
Location: Helgoland, Germany
System/Technology: Hydrogen
Services: Solution development / Feasibility studies
Industry Branch/Type of Plant: Green Energy, Power Generation
Client: Versorgungsbetriebe Helgoland GmbH (local utility operator)
Activity period: 2022
Project description
Three projects in the AquaVentus family have joined forces for an initial project to supply the island of Helgoland with climate-neutral heat using green hydrogen: AquaPrimus (offshore electrolysis), AquaDuctus (pipeline) and AquaCore (local direct utilization).
In the value chain, an offshore wind turbine (WT) with electrolysis unit from the AquaPrimus subproject will be installed in the area of the wind farms off Helgoland. It autonomously produces green hydrogen for local direct applications. The electricity for electrolysis is generated directly from the WTG. Surplus electricity from the WTG will be transported to the mainland by cable. Using an innovative hydrogen pipeline from the AquaDuctus project, the green hydrogen produced will be piped directly to the Helgoland utilities after landing at the Nordostbohlwerk. There it will be converted into heat and fed into the district heating network.
The AquaCore schedule is based on the AquaPrimus and AquaDuctus subprojects. Realization is scheduled to take place by 2026.
