In those cases, an enhanced geothermal system (EGS) can be used to create a human-made reservoir to tap that heat for energy. In an EGS, fluid is injected deep underground under carefully controlled conditions to create new fractures and cause pre-existing fractures to re-open, creating permeability.
With further development of EGS to manage induced seismicity risk and increase system flexibility, EGS could provide stable baseload and potentially dispatchable electricity in clean energy systems. Enhanced geothermal systems (EGS) have the potential to supply clean and firm energy in the form of electricity and/or direct heat.
a, Enhanced geothermal system development begins with drilling of an injection well. b, Fractures are created using multistage stimulation. c, A production well is then drilled and stimulated. d, Energy is produced from the wells. e, Plug and perf technology to control stimulation.

An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies expand the availability of geothermal resources through stimulation methods, such as ''hy
