What We Do
The mission of the Office of Geothermal (OG), formerly the Geothermal Technologies Office (GTO), is to increase geothermal energy deployment through research, development, and demonstration (RD&D) of innovative technologies that enhance exploration and production.
OG funds RD&D through three office sub-programs:
The Pilots & Demonstrations sub-program manages:
- Pilot projects, particularly pilots for pre-commercial-scale enhanced geothermal systems (EGS) deployments in new geologies/structural environments
- Improving the fracturing techniques for EGS and the thermal cycling protocols for Thermal Energy Storage (TES)
- Managing the Utah FORGE project
The Commercial Scale-Up sub-program manages:
- Identifying and enacting new methods for accelerating and streamlining the permitting process
- All modeling associated with geothermal power and storage uptake
- The Geothermal Data Repository (GDR) and implementation of real-time interface capabilities among OG analytical tools
- Tracking office-wide progress against metrics and goals
- Leading analysis and assessments that outline and estimate the value of geothermal electricity generation to the grid
- Identifying products that ISOs/RTOs and vertically integrated utilities could leverage for firm and flexible geothermal power
- Analyzing the geothermal workforce and developing workforce initiatives to engage skilled workers in scale up of industry
- Increasing the general public’s awareness and acceptance of geothermal energy as baseload source of energy
The Technology Research & Development sub-program manages:
- Developing and deploying advanced geophysical tools and inversion methods, integrated characterization workflows, and AI-driven sensing tools or analysis methods
- Cost-shared drilling programs to ground-truth exploration advances
- Increasing drilling speed and reducing materials costs, partnering with oil & gas service companies to adapt technologies and workflows for high-temperature, hard-rock environments
- Improving the efficiency of organic rankine cycle (ORC) power conversion, improved pump efficiency/reliability, and head losses across the full circulation system
- Assessing opportunities for rare earth elements and critical materials extraction from geothermal brines
We work in partnership with industry, academia, the U.S. Department of Energy (DOE) national laboratories, and others on RD&D activities focused on these research 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 EGS Pilot Demonstrations.Hydrothermal Resources
Improving geothermal exploration, subsurface characterization, and drilling to reduce overall geothermal deployment costs. Initiatives include Hidden Systems, Lithium, and Drilling Demonstrations.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 District-Scale Geothermal Energy Pilots 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 U.S. Geothermal Market Report, Permitting for Geothermal Power Development Projects, GRID, and the Geothermal Data Repository (GDR).
OG advances the nation's potential to generate electricity and produce heating and cooling for U.S. homes and businesses 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 OG funding opportunities.
Here's how the cycle of a typical OG fiscal year works:
- OG receives taxpayer money, appropriated to OG by Congress.
- To ensure money is released the right way, OG reaches out to diverse stakeholders for strategic direction and planning (typically public/private companies, municipalities, universities, and national laboratories).
- OG makes these plans available to the public.
- OG offers the public opportunities to receive funding for geothermal projects. Entities apply, and after an independent merit review and negotiation, OG selects projects and releases funding to those entities. These projects may perform research, development, and demonstration activities that will drive more geothermal use.
- OG then monitors how the entities spend those funds.
- Finally, OG 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, OG is stimulating the growth of the geothermal industry and helping the nation leverage its abundant heat resources.
