Lernziele

The module provides an overview of geothermal technologies and their application for the generation of electricity, heating & cooling and for underground thermal energy storage. The students understand the geothermal heat source, properties of the subsurface and thermal transfer mechanisms. They apply knowledge to the basic design of local heat distribution systems, the integration of low temperature geothermal heat sources and ground-source heat pumps in the energy supply systems and the use of geothermal storage options for the balancing of seasonal heating&cooling demands with asynchronous supply and demand cycles as well as the basic economic considerations of geothermal energy generation and heat network integration.
