Using CPG to Support Wind and Solar Energy
CPG (CO2 Plume Geothermal) technologies are geothermal power systems that use geologically stored CO2 as the geothermal heat extraction fluid. This study investigates the potential that CPG may have for supplying electricity demand as part of a renewables-heavy electricity system. It finds, among other conclusions, that CPG technology can enable using geothermal energy in North Dakota for electricity generation and/or energy storage, but that policy (e.g., a CO2 tax) is needed to justify using renewable energy technologies on a cost-basis compared to natural gas power plants.
