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 ...
