Today, the U.S. Department of Energy (DOE) announced a funding opportunity of up to $74 million for several pilot projects that will test the efficacy and scalability of enhanced geothermal systems (EGS). Directed by President Biden’s landmark Bipartisan Infrastructure Law (BIL), the pilot projects will use innovative technology and a variety of development techniques to capture the Earth’s abundant heat resources in diverse geologic settings. Through this investment, DOE hopes to demonstrate the growth and ultimate potential for geothermal energy to provide reliable, around-the-clock electricity to tens of millions of homes across the country.  

This is DOE’s first funding opportunity for geothermal energy since the launch of the Enhanced Geothermal Shot^TM, part of DOE’s Energy EarthShots Initiative, which seeks to cut the cost of geothermal energy 90% by 2035. 

Geothermal energy currently generates about 3.7 gigawatts of electricity in the United States, but a new analysis shows it could provide 90 gigawatts of firm, flexible power to the U.S. grid by 2050, as well as heating and cooling solutions nationwide. This substantial geothermal energy potential is, however, largely inaccessible with conventional geothermal technologies. The use of geothermal energy for electricity requires three elements: heat, fluid, and a permeable section of the Earth’s crust. While heat exists everywhere underground, many locations lack adequate water and/or permeability. EGS employ human-made underground reservoirs to enable the fluid flow necessary to draw geothermal energy to the surface, where it can be captured to power homes across the country. Achieving this goal would make geothermal energy a clean, cost-effective option across the country, while spurring progress toward President Biden’s goals of 100% carbon-pollution-free electricity by 2035 and net-zero emissions by 2050.  

Applications for the BIL-funded EGS Pilot Demonstrations will be accepted over multiple rounds. First-round letters of intent are due March 8, 2023, and first-round applications will be due July 7, 2023. Learn more and read the full Funding Opportunity Announcement.
