Summary
New geothermal development techniques and technologies could help the U.S. increase current installed capacity by more than 20 times, DOE concluded in its pathways report.
There is “enormous potential” for geothermal expansion, Secretary of Energy Jennifer Granholm said in a statement. “With strong public-private partnerships we can lower costs for this hot technology to expand access for cleaner, more reliable power to communities across the nation.”
“Next-generation geothermal can economically provide 90 GW of the 700 to 900 GW of [additional] clean firm power needed for a decarbonized economy by 2050,” according to the DOE report. Other technical and market factors could triple expected deployment, it said.
Currently, most geothermal power production occurs in the Western U.S. due to the location of appropriate reservoirs, but DOE said advanced-generation deployment techniques mean that by 2050 opportunities could exist in at least 18 states.
