Enhanced Geothermal Systems (EGS) Induced Seismicity

Induced seismicity associated with energy production and waste disposal will become an increasingly important issue (geothermal, CO2 sequestration, and oil and gas, etc.) as energy production in a climate-constrained earth progresses. Although induced seismicity has been noted for many years and associated with a variety of causes, recent attention has been focused on oil and gas, geothermal, and potential CO2 sequestration sites. This web site is meant to provide useful information regarding these three areas.

Subsurface Technology and Engineering Research, Development and Demonstration (SubTER)

Geothermal Systems

SubTER: The subsurface provides more than 80 percent of the energy used in the US and serves as a vast reservoir for CO2, nuclear waste, and energy storage. Despite decades of research, game-changing advances are needed to revolutionize utilization of the subsurface for energy production and storage while also protecting the environment.
