Fraunhofer IEG - Applied research for reshaping the heat sector [10] Vortragssprache Englisch

The Fraunhofer Research Institution for Energy Infrastructures and Geothermal Systems IEG carries out research in the fields of integrated energy infrastructures, geothermal energy and sector coupling for a successful energy transition at seven locations in Germany.
We develop ideas, technologies and strategies for the next phase of the transformation the energy systems and see ourselves as independent pioneers in politics, economics, regulation and society. The main topics are hydrogen, energy infrastructures and sector coupling, heat mining and storage, borehole technologies, georesources and the development of the technological components needed for this, energy technology and CO2 capture.
One of those key technological components are heat pumps and therefor a key research field at IEG.
We aim to develop in close cooperation with manufactures the next generation of heat pumps and their integration into green district heating and cooling networks.
We focus on efficiency as well as extending the operational temperature range for industrial applications. At component we level look into compressors, heat exchangers and different form of expansion devices such as ejectors and expanders.
The research at system level touches on advanced predictive control, minimizing the amount of refrigerant and lubricant distribution. Regarding refrigerant we put a special emphasis on natural refrigerants. At IEG are able provide full characterizations of heat pumps considering both the dynamics of heat source and sink. This is because of our unique holistic approach to the transformation of the heat sector.
Infrastructure wise we aim to optimize the control of complex heating networks including heat pumps and other thermal systems for example heat storages. In this talk we will be presenting the research institution, its lab infrastructure as well case studies of recent and ongoing research projects.
Among them a project where we use a closed down mine in Bochum for seasonal heat storage linking it up with the city’s district heating network by means of a cascaded heat pump.
