Requires the Secretary of Energy to ensure at least one FORGE site has capabilities to test next-generation geothermal systems in supercritical conditions within 1 year of enactment.
Directs the Secretary to award milestone-based grants for deep drilling projects in unique geodynamic settings covering tectonic stress characterization, laboratory work, drilling, flow testing, and power production.
