520 3 |a This study shows that a hot dry rock (HDR) geothermal space heat system proposed for the National Aeronautics and Space Administrations's Wallops Flight Center (WFC) will cost $10.9 million, saving $4.1 million over the existing oil heating system over a 30-yr lifetime. The minimal, economically feasible plan for HDR at WFC is shown to be the design of a single-fracture reservoir using a combined HDR preheat and a final oil burner after the first 4 years of operation. The WFC cost savings generalize and range from $3.1 million to $7.2 million for other HDR sites having geothermal temperature gradients ranging from 25°C/km to 40°C/km and depths to basement rock of 2400 ft or 5700 ft compared to the 30°C/km and 9000 ft to basement rock at WFC.
