IMI, an electrolyzer equipment provider, has supplied a proton exchange membrane (PEM) electrolyser to a cutting-edge research project in Zittau, Germany. The project, conducted by the Fraunhofer-Institution for Energy Infrastructures and Geothermal Systems, is part of the IntegrH2ate research project funded by the German government. The initiative aims to explore the feasibility of utilizing hydrogen by-products in district heating systems. By setting up a test facility at the Stadtwerke Zittau site, the project will investigate the extraction of heat from hydrogen generation using a PEM electrolysis process and a high-temperature heat pump. The waste heat generated will be integrated into the municipal district heating network to assess the technology's viability. IMI's VIVO electrolyser was chosen for its flexibility, scalability, and suitability for research purposes. The project underscores the importance of examining hydrogen's by-products in enhancing sustainability and advancing district heating technologies in alignment with Germany's heating objectives. The IntegrH2ate project serves as a significant step towards understanding technical aspects of hydrogen production and by-product usage, positioning hydrogen as a key player in future energy systems.
