HB7568, the “Hot Rock Act,” is a federal geothermal energy research and development bill focused on advancing next-generation geothermal systems, especially hot dry rock, superhot, and supercritical geothermal resources. It directs the Department of Energy to create multiple grant and demonstration programs for high-temperature drilling, completions, sensing equipment, fluid-property research, reservoir creation, and milestone-based technology development. The bill also authorizes a frontier observatory and test site for field research and demonstration, with an emphasis on solving the technical barriers to commercial-scale geothermal power and industrial heat production.
The bill further requires the Department of the Interior, through the U.S. Geological Survey, to establish research and monitoring programs on seismicity, rock mechanics, deep basement rock mapping, and groundwater impacts in areas affected by geothermal testing. In addition, it creates a Department of Labor workforce cross-training program for workers from the oil and gas sector and related trades, with training in geosciences, engineering, drilling, and technical occupations. It also directs the Department of Energy to provide technical assistance to federal land agencies and amends the Energy Policy Act of 2005 to expand categorical exclusions for geothermal exploration and confirmation activities under federal environmental review processes.
The bill would not directly regulate private geothermal operations in the same way as a permitting statute, but it would significantly expand federal research, demonstration, workforce, and interagency support for geothermal development. It authorizes substantial appropriations across fiscal years 2027 through 2031 for DOE, USGS, and DOL programs, and it amends section 390 of the Energy Policy Act of 2005 to add geothermal exploration and confirmation to categorical exclusion language, potentially streamlining certain federal environmental reviews for geothermal projects. It also creates a DOE technical assistance role for Bureau of Land Management and Forest Service offices handling federal authorizations for hot dry rock geothermal projects.
Based on the bill text and the limited context available, the measure appears generally supportive of geothermal development and likely to draw favorable attention from clean energy advocates, research institutions, and parts of the energy industry interested in diversification. The bipartisan introduction by Representatives Auchincloss and Amodei suggests an effort to frame geothermal as a practical energy and industrial policy issue rather than a partisan one. No committee transcript or vote record is available here, so there is no documented opposition or recorded floor sentiment in the provided materials.
The main likely points of contention are the bill’s federal spending commitments, the expansion of categorical exclusions for geothermal exploration, and the environmental and subsurface-risk issues associated with deep drilling, induced seismicity, and groundwater monitoring. Environmental stakeholders may scrutinize the streamlined federal authorization provisions and the adequacy of monitoring safeguards, while fiscal skeptics may question the scale of authorized appropriations for research, demonstration, and workforce programs. By contrast, supporters are likely to emphasize the bill’s role in accelerating domestic geothermal deployment, leveraging oil-and-gas expertise, and reducing technical barriers to commercial-scale projects.
