Project description
The TransHyDE project Helgoland, funded by the German Federal Ministry of Education and Research, focuses on the hydrogen transport technology „LOHC“. In this research project, nine partners from science and industry have networked with the island of Helgoland to develop a LOHC-based supply chain for green hydrogen produced offshore. The route of the supply chain runs from the Schleswig-Holstein coastal sea via the port of Helgoland to the port of Hamburg and thus to hydrogen consumers in the metropolitan region and beyond. In the LOHC supply chain, Helgoland is considered as the place of storage (hydrogenation) and Hamburg as the place of release (dehydrogenation).
The basis for this originally came from the AquaPortus project, which is part of the AquaVentus project family. After the research phase, the project was to be implemented in AquaPortus.
The aim of this study is to investigate the technical and economic feasibility of using waste heat from the LOHC plant (hydrogenation) and the CO2 reduction that this could bring to heat generation for Helgoland.
