2. The potential for using sedimentary basins for electricity generation is vast and a nonnegligible capacity may be profitably developed. Our supply curves that assumed p50 data and a geothermal temperature gradient of 35 °C/km suggest that there are 10s of GW e of electricity generation potential in the U.S. in deep saline formations alone (Figure ). Our results also suggest that there is ~500 MW e (13% of current installed US capacity) of additional potential with water or ~275 MW e (7% of current installed US capacity) with CO 2 , both below Ormat's 2019 average PPA price of 85 $/MW e -h. While approximately 740 MtCO 2 of geologically stored CO 2 is required to realize this 275 MW e capacity with CO 2 -based power plants, there is nothing constraining the development of this 500 MW e capacity with water-based power plants. Overall, this finding suggests that sedimentary basin geothermal resources should not be excluded from geothermal resource assessments.
