What We Do
The mission of the Geothermal Technologies Office (GTO) is to increase geothermal energy deployment through research, development, and demonstration of innovative technologies that enhance exploration and production.
We work in partnership with industry, academia, the U.S. Department of Energy national laboratories, and others on research, development, and demonstration activities focused on these areas:
Enhanced Geothermal Systems (EGS)
Advancing commercial viability of EGS, with a focus on reservoir characterization, enhancement, and sustainability. Initiatives include FORGE, Wells of Opportunity, and Enhanced Geothermal Systems (EGS) Pilot Demonstrations.Hydrothermal Resources
Improving geothermal exploration, subsurface characterization, and drilling to reduce overall geothermal deployment costs. Initiatives include Hidden Systems, GeoFlight, and Drilling RD&D.Low Temperature and Coproduced Resources
Improving the efficiency of low-temperature (<300° F) geothermal systems and expanding their utility through additional revenue streams, such as opportunities for geothermal energy storage. Initiatives include Community Geothermal Heating and Cooling Design and Deployment and Federal Geothermal Partnerships.Data, Modeling, and Analysis
Addressing nontechnical barriers to geothermal deployment with environmental and resource assessments, data stewardship, and analytical tools that advance geothermal exploration and development. Initiatives include the GTO Multi-Year Program Plan, the U.S. Geothermal Power Production and District Heating Market Report, Permitting for Geothermal Power Development Projects, and the Geothermal Data Repository (GDR).
GTO advances the nation's potential to generate electricity and produce heating and cooling for U.S. homes from domestic geothermal resources by releasing competitive solicitations. These take the forms of Notice of Funding Opportunities (NOFOs), Notices of Technical Assistance, Prizes, Competitions, and Small Business Innovation Research and Small Business Technology Transfer Programs. Learn more about past and present GTO funding opportunities.
Here's how the cycle of a typical GTO fiscal year works:
- GTO receives taxpayer money, appropriated to GTO by Congress ($118M in 2025).
- To ensure money is released the right way, GTO reaches out to diverse stakeholders for strategic direction and planning (typically public/private companies, municipalities, universities, and national laboratories).
- GTO makes these plans available to the public.
- GTO offers the public opportunities to receive funding for geothermal projects. Entities apply, and after a GTO review and negotiation, GTO selects projects and releases funding to those entities. These projects may perform research, development, and demonstration activities that will drive more geothermal use.
- GTO then monitors how the entities spend those funds.
- Finally, GTO releases public data and reports, and hosts events showcasing the projects’ results and progress for broad accessibility.
Why Geothermal Matters
Geothermal energy, which comes from the heat beneath our feet, is more vital than ever:
SUSTAINED – Geothermal resources will be continually replenished for billions of years and can supply power around the clock.
RELIABLE – Geothermal energy provides baseload power and delivers a high capacity factor—typically ~90%—meaning that geothermal power plants can operate at maximum capacity nearly all the time. This high capacity factor allows geothermal power generation to balance changing loads on the grid, making it a critical part of the nation's energy system.
VERSATILE – Geothermal is a total energy solution, providing electricity, heating and cooling, even access to critical minerals like lithium.
HUGE POTENTIAL – Geothermal has vast potential to provide energy solutions across the entire nation.
Despite its benefits, geothermal energy is still largely untapped in the United States. By researching, developing, and demonstrating innovative geothermal technologies, GTO is stimulating the growth of the geothermal industry and helping the nation leverage its abundant heat resources.
