The Geothermal Systems Program is focused on developing innovative technologies that can identify and characterize  conventional and hidden natural hydrothermal systems; and characterizing, developing, and sustaining enhanced geothermal systems through the use of coupled process models, microearthquake (MEQ) monitoring, and laboratory studies.

Our team applies expertise in using chemistry to study the temperature of geothermal reservoirs;  characterizing the subsurface by examining coupled geophysical attributes; locating and mapping surface fluid flux; and analyzing prospective geothermal regions to identify geothermal systems and better constrain resource potential.

We develop approaches to implement, monitor, and model enhanced geothermal systems (EGS), where hot rock permeability is artificially created or enhanced through hydraulic, thermal, and/or chemical stimulation. Berkeley Lab has played a major role in coupled process modeling and induced seismicity monitoring of several DOE-EGS demonstration projects. We recently diversified to include direct-use applications such as brine desalination, mineral recovery, district heating and cooling, and thermal-reservoir energy storage.
