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. [ 1 ]
Fervo Energy is an energy resource company focused on harnessing heat through enhanced geothermal systems (EGS). It was co-founded in 2017 by Tim Latimer, a mechanical engineer who worked as a drilling engineer at BHP until 2015.
The company currently has a demonstration project underway about 30 miles south of Bend, Oregon in the Deschutes National Forest.The Newberry EGS Demonstration [5] is located on an existing Federal lease designated for geothermal use and is supported by a committee that includes representatives of the community, environmental groups, government and the geothermal industry.

Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...
The act gives the Chairman of the Project the authority to designate an appropriate Federal agency to guarantee loans for the commercial applications of geothermal energy. The head of the designated agency is authorized, in consultation with the Secretary of the Treasury , to guarantee loans from lenders to qualified borrowers for the ...
EGS Collab: The Enhanced Geothermal Systems (EGS) Collab Project is a collaboration of eight national laboratories and six universities who are working to improve geothermal technologies. EGS conducts field experiments to better understand and model rock fracturing and other elements of geothermal energy. [13] The experiment was a precursor to ...
An engineered geothermal system is a geothermal system that engineers have artificially created or improved. Engineered geothermal systems are used in a variety of geothermal reservoirs that have hot rocks but insufficient natural reservoir quality, for example, insufficient geofluid quantity or insufficient rock permeability or porosity, to ...
Some subsurface water associated with geothermal sources contains high concentrations of toxic elements such as boron, lead, and arsenic. Injection of water in enhanced geothermal systems may induce seismicity. Earthquakes at the Geysers geothermal field in California, the largest being Richter magnitude 4.6, have been linked to injected water ...
