In this presentation, NREL provides an initial estimate of the geothermal resource in major U.S. sedimentary basins by (1) providing a preliminary review of major sedimentary basins in the United States; (2) delineating and mapping areal extent and depth contours of each basin in Geographic Information Systems (GIS); (3) estimating the temperature profile for each basin (assume single temperature gradient for each basin); (4) calculating basin volume as a function of temperature; and (5) converting volumes to heat in place and electricity generation potential.
