This document discusses GreenFire Energy's ECO2GTM geothermal power technology, which uses supercritical carbon dioxide in closed loops to generate electricity from underground heat sources. This technology could significantly expand viable geothermal resources by not requiring natural fractures or permeability. The document notes California's need for flexible power sources to integrate rising renewable generation. It argues ECO2GTM could help meet this need by providing both baseload and flexible power with zero carbon emissions and no water use. The technology faces technical, economic, regulatory and contractual barriers, and the document requests support overcoming these barriers to develop ECO2GTM in California.
