Comparative Analysis of Power Plant Options for Enhanced Geothermal Systems (EGS)

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
