Comparative Analysis of Power Plant Options for Enhanced Geothermal Systems (EGS) [PDF]
Energies, 2014 Enhanced geothermal systems (EGS) extract heat from underground hot dry rock (HDR) by first fracturing the HDR and then circulating a geofluid (typically water) into it and bringing the heated geofluid to a power plant to generate electricity. This study

Hydraulic stimulation strategies in enhanced geothermal systems (EGS): a review
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2022 In enhanced geothermal systems (EGS), the natural permeability of deep rocks is normally not high enough and needs to be increased. Permeability increase can be achieved through various stimulation methods, such as hydraulic, chemical, and thermal ...

Efficient workflow for simulation of multifractured enhanced geothermal systems (EGS)
Renewable Energy, 2019 The increasing demand for clean energy with minimum environmental impact motivates development of geothermal energy. Simulating a geothermal reservoir is complex and time consuming, mainly because of the systems spatial and temporal non-isothermal nature

Enhanced-Geothermal-Systems (EGS), Hot-Dry-Rock Systems (HDR), Deep-Heat-Mining (DHM)
Geothermal Energy, 2021 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 ...

Development of Enhanced Geothermal Systems (EGS) in Northern Alberta
, 2015 In the province of Alberta a huge amount of energy is needed for diverse applications. Specifically, the demand for heat is limited to a few locations such as the oil sands operation regions and metropolitan areas. Oil sands processing facilities near Fort McMurray and direct heat provision for different applications in the City of Edmonton are two of ...
