Product Description
This analysis evaluates the role of geothermal power in the future energy portfolio of the United States. Geothermal power is a proven technology with a large resource base, and the use of flash steam technology has relatively low capital costs that translate to a competitive cost of electricity. However, the characteristics of geologic formations are highly variable and are a barrier to broad implementation of geothermal power. Further, the naturally-occurring CO2 in geofluid leads to relatively high greenhouse gas emissions from geothermal power plants that use flash steam technology.
