A current study by the Fraunhofer IEG shows that deep geothermal energy could make a significant contribution to climate-neutral heat supply in cities, reports ingenieur.de. The example of Wuppertal illustrates that even regions that have been little developed so far offer relevant potential – provided that technical, economic, and regulatory issues are specifically addressed. This is the conclusion of a feasibility study conducted by the Fraunhofer Institute for Energy Infrastructures… Read more »

A new nationwide geothermal map shows for the first time where near-surface geothermal energy can be harnessed using geothermal probes. Developed as part of the WärmeGut research project led by the LIAG Institute for Applied Geophysics in Hanover, in collaboration with the Georg August University of Göttingen, geoENERGIE Konzept GmbH, and all 16 state geological surveys, the interactive map is now freely accessible in the GeotIS geothermal information system. Geothermal energy, the year-round available heat from... Continue reading

With the phase-out of coal, it is equally important to develop new heat sources for municipalities and industry, as well as to shape the structural transformation in coal regions. The "Fraunhofer Living Lab for Geothermal Energy, Geotechnologies and Georesources – Geo³" achieves both by creating a research infrastructure in the Aachen city region that is unique in Europe and explores the potential of deep geothermal energy in North Rhine-Westphalia. And by… Read more »

Heat pumps are a climate-friendly and efficient way to heat and cool buildings. In Sweden, a country with long, cold winters, they are particularly popular and widespread. According to the German Heat Pump Association (BWP), renewable energy sources account for almost 55 percent of Sweden's energy consumption, while Germany only reaches 15,5 percent. How did Sweden manage to… Read more »
