Summary

The project 'Large-scale deep geothermal power plants' follows a radically new approach to the exploitation of geothermal power. It relies on an underground power plant for gaining electricity from district and process heat. The concept foresees a complex mining infrastructure to construct closed systems allowing for controlled and continuous energy absorption at great depths (around 6,000 m). Currently an interdisciplinary group of experts is investigating the principal feasibility of this concept.

Zusammenfassung

Das Projekt "Geothermie-Tiefenkraftwerk" stellt einen neuen Verfahrensansatz in der Nutzung geothermischer Energie dar. Fern- und Prozesswärme wie auch 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. Derzeit wird von einer Forschungsgruppe die prinzipielle Machbarkeit für dieses Projekt untersucht.
