Urban Heating

Geothermal heat is perfectly suited for heating buildings in the colder regions of the world. However, the usage of this sustainable and environmentally-friendly resource is limited due to the need of district heating systems. Investments in building of district heating are very costly. Besides the challenge to develop new district heating systems there is also a transformation of energy usage going on in several countries of Europe: coal will no longer be used for power generation. As a side effect, the accompanied heat, traditionally delivered by district heating nets, will no longer be available in the future. Again geothermal heat is perfectly suited for substitution. However, geothermal heat does typically occur with temperatures lower than needed by old district heating systems, which defines another technological challenge
