The FY25 Phase I Release 2 features one topic related to enhanced geothermal systems (EGS). Funding for this topic area is provided by the Infrastructure Investment and Jobs Act (Bipartisan Infrastructure Law).
This subtopic focuses on improving elastomeric materials used in harsh downhole geothermal environments, particularly in EGS development and high temperatures (over 250°C for long-term use and 300°C for short-term use, up to 375°C for superhot systems). Applications should focus on improving elastomeric materials specifically for use in geothermal wells, including for use in seals, o-rings, zonal isolation devices, pumps, valves, motors, and wellbore monitoring tools.
See Topic C60-07 in the FY25 Phase I Release 2 topics document for more details on this topic area, and the SBIR website for information on applying. A Phase I application should focus on proof of concept via engineering design, materials development, modeling, and/or laboratory scale testing (as applicable). Phase I efforts should be scalable to subsequent Phase II development including model validation, prototype development, and/or pilot or field-scale testing (as applicable).
