TransHyDE Project on LOHC Waste Heat Recovery

This document is a technical report detailing the TransHyDE project focused on waste heat recovery using Liquid Organic Hydrogen Carrier (LOHC) technology in Helgoland, Germany. Funded by the German Federal Ministry of Education and Research, the project involves nine partners from academia and industry working to establish a LOHC-based supply chain for green hydrogen produced offshore. The supply chain extends from the Schleswig-Holstein coastal sea to the port of Hamburg, with Helgoland serving as the hydrogen storage site. The report outlines the project's objective to assess the technical and economic feasibility of utilizing waste heat from the LOHC plant for heating in Helgoland, including the design and integration of necessary infrastructure into the existing district heating network. It also discusses the preparation of a feasibility study, evaluation of energy balances, and profitability analysis, including investment costs and potential CO2 reductions.
