This bill amends the Energy Independence and Security Act of 2007 to include next-generation geothermal systems, defining closed-loop and supercritical geothermal systems, and directing research and development activities. It specifically addresses enhanced geothermal systems, closed-loop geothermal research, and next-generation geothermal testing, focusing on topics such as well completion, materials development, sensor development, and water-rock geochemistry. The bill also establishes a Next-Generation Geothermal Center of Excellence, provides for commercial-readiness innovation grants, and authorizes appropriations for the Department of Energy. Additionally, it calls for updates to the geothermal resource assessment and progress reports to congressional committees.
Next-Generation Geothermal Research and Development Act
This bill directs the Department of Energy (DOE) to support the development of next-generation geothermal systems, such as closed-loop geothermal systems in supercritical conditions. Specifically, the bill expands the Energy Independence and Security Act of 2007 to modify and establish geothermal energy programs, such as programs concerning research and development, grants, and data management.
DOE must support a program of research, development, demonstration, and commercial application for next-generation geothermal systems. DOE may administer grants for carrying out certain focus areas of the program. DOE must also ensure that at least one Frontier Observatory for Research in Geothermal Energy (FORGE) field research site has the capabilities to include next-generation geothermal testing.
Additionally, DOE must provide grants for (1) the continuation and expansion of research, development, demonstration, testing, and commercial application activities applicable to FORGE sites; and (2) the establishment of a next-generation geothermal systems center of excellence.
DOE must also provide grants to accelerate the development, testing, and implementation of innovative technologies to improve the commercial-readiness of geothermal energy projects using next-generation geothermal systems.
DOE must expand its repository of geothermal drilling information to include publicly available subsurface data, including data reported as part of fossil fuel and mining operations. DOE must also periodically update the repository to improve its functionality and usability.
The bill authorizes the Department of the Interior to commission the drilling of supercritical geothermal exploration boreholes in certain areas to provide control points for deep heat mapping and geothermal development.
