Enhanced geothermal are engineered geothermal systems in naturally hot dry rock where natural fluid convection and permeability are not found. The term comes from the fact that conventional geothermal power plants are often tapping into natural near surface convective systems with high water permeability. Bringing that heat to the near surface also heats the surrounding rock over hundreds of thousands of years so one way to "enhance" the output of traditional geothermal power plants was to theoretically engineer permeability into these surrounding rock formations. Fervo's facility is built next to an existing conventional geothermal power plant.
