Title:
Abstract:	The “Deep geothermal power station” project represents a new process for the exploitation of geothermal energy. District heating and heating for industrial purposes as well as electricity can be produced in a geothermal power station. The heat extraction will be controlled and continuous in a closed circulation system using drillings from a mined system of tunnels at a depth of 6,000 m. In order to overcome the high temperatures and rock pressures to be expected, interdisciplinary collaboration between several professions will be required. Das Projekt “Geothermietiefenkraftwerk” stellt einen neuen Verfahrensansatz in der Nutzung geothermischer Energie dar. Fernund Prozesswärme sowie Elektrizität werden hierbei in einem geothermischen Großkraftwerk erschlossen. Die Wärmegewinnung erfolgt kontrolliert und kontinuierlich in einem geschlossenen Kreislauf mittels Bohrungen von einem bergmännisch aufgefahrenen Stollensystem in einer Teufe von 6.000 m. Zur Beherrschung der hohen Temperaturen und Gebirgsdrücke ist eine interdisziplinäre Zusammenarbeit mehrerer Fachdisziplinen erforderlich.
