With technological advancements in deep-well drilling and material improvements, Enhanced Geothermal Systems technology costs could be reduced, and geothermal energy could make substantial contributions to a net-zero energy system over the long term.
An enhanced geothermal system (EGS) produces carbon-free power by harnessing the earth’s heat from far below the ground. An EGS accesses the heat by injecting water at high pressure from wells on the surface. The water creates fractures in deep rock formations, and the rocks, in turn, heat up the water. The water is then pumped back up, carrying enough heat to produce steam for power generation. EGS promises to harness the inexhaustible heat of the earth’s crust to help power the world for generations to come.
