Enhanced-Geothermal-Systems, Hot-Dry-Rock Systems, Deep-Heat-Mining

, 2013
With Enhanced-Geothermal-Systems (EGS) the deep underground is used as a source of heat for the production of electrical and thermal energy irrespective of the hydraulic properties of the deep heat reservoir. In other words the rocks are hot at depth irrespective of whether or not they qualify as aquifers or aquitards.

Enhanced-Geothermal-Systems (EGS), Hot-Dry-Rock Systeme (HDR), Deep-Heat-Mining (DHM)

Geothermal Energy, 2011
Mit dem Enhanced-Geothermal-System (EGS) soll der tiefere Untergrund als Warmequelle zur Stromerzeugung und Warmegewinnung genutzt werden (Abschn. 4.2). Synonyme sind Hot-Dry-Rock (HDR) oder Deep-Heat-Mining (DHM). Der Begriff HDR stammt aus der Anfangsphase dieser Technologie-Entwicklung, in der man noch von „trockenen“ Verhaltnissen in groser Tiefe ...
