HR-7568-119
Referred to the Committee on Science, Space, and Technology, and in addition to the Committees on Natural Resources, and Education and Workforce, for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned.
Sponsored by Jake Auchincloss (D-MA)
What it does
The Hot Rock Act would establish multiple federally funded programs to advance "hot dry rock" geothermal energy — a next-generation technology that extracts heat from deep, impermeable rock formations. It would authorize grants for research, a field testing site, and milestone-based awards totaling up to $102 million per year from 2027–2031. The bill would also create a workforce cross-training program for oil and gas workers transitioning to geothermal jobs, direct the U.S. Geological Survey to map deep rock formations and monitor groundwater, and streamline federal permitting for geothermal exploration by adding geothermal projects to an existing categorical exclusion from full environmental review under the National Environmental Policy Act.
Who benefits
Energy technology companies and startups working on next-generation geothermal systems. National laboratories and universities receiving research grants. Oil and gas workers (drillers, engineers, welders, pipefitters, electricians) who gain access to cross-training for geothermal jobs. Workers and communities in "energy communities" — areas economically dependent on fossil fuel industries — who are explicitly prioritized for workforce programs. Geothermal energy developers who would face a faster, less burdensome federal permitting process. Electricity consumers broadly, if the technology achieves commercial scale and lowers energy costs. States and territories that would receive geological mapping data from USGS.
Who is hurt
Competing renewable energy sectors (solar, wind) that do not receive equivalent new federal support and may face indirect competitive disadvantage if geothermal achieves cost parity. Environmental and community groups near proposed geothermal test sites who may have less opportunity to comment on projects due to the expanded categorical exclusion from full NEPA review. Taxpayers who bear the cost of the authorized appropriations. Conventional geothermal energy companies using naturally occurring reservoirs, who are not the focus of this bill and may face a competitive shift toward engineered systems. Communities near test sites who could be affected by induced seismicity — a known risk of hydraulic stimulation used in hot dry rock projects — though the bill does establish a seismicity monitoring program.
Supporters argue
Supporters argue that hot dry rock geothermal energy could provide always-on, carbon-free electricity accessible virtually anywhere in the country — unlike solar or wind, which depend on weather conditions — and that federal investment is necessary to bridge the gap between early-stage research and commercial viability, just as federal support accelerated shale gas development. They contend the workforce cross-training provisions are particularly efficient, leveraging existing skills from the oil and gas sector — drilling engineers, reservoir engineers, rig workers — whose expertise transfers directly to geothermal, reducing training costs and supporting communities facing fossil fuel industry decline. They also argue the permitting streamlining is narrowly targeted at exploration activities, consistent with existing categorical exclusions already in place for oil and gas.
Opponents argue
Opponents argue that the bill's expanded categorical exclusion from NEPA review for geothermal exploration removes an important public check on projects that carry real environmental risks — particularly induced seismicity and groundwater contamination from hydraulic stimulation of deep rock formations — risks the bill itself acknowledges by mandating a monitoring program. They contend that at up to $510 million in authorized spending over five years, the bill represents a significant federal bet on an unproven technology that has not yet achieved commercial scale anywhere in the world, and that market mechanisms, not targeted federal subsidies, should determine which energy technologies succeed. They further argue that the milestone-based grant structure, while results-oriented, still leaves broad discretion to the Secretary of Energy with limited congressional oversight of individual awards.
Constitutional context
The bill rests on Congress's Commerce Clause authority (Art. I, §8, cl. 3) and Spending Clause power to fund research and workforce programs. The NEPA categorical exclusion expansion is a statutory modification by Congress and does not raise major questions doctrine concerns under West Virginia v. EPA (2022), since Congress — not an agency — is directly authorizing the change. Post-Loper Bright (2024), any agency regulations implementing the bill's grant programs would face independent judicial review rather than deference, though the bill's relatively specific statutory directives limit the scope of agency discretion.
Checks and balances
The executive branch (Departments of Energy, Interior, and Labor) gains new spending and program authority; Congress retains control through the authorization-appropriations process, meaning funds are not guaranteed without separate appropriations acts, and the bill's five-year sunset on authorizations provides a built-in legislative review point.
Historical precedent
The Energy Policy Act of 2005 similarly established categorical exclusions for oil and gas exploration on federal lands and authorized DOE research programs for emerging energy technologies, providing a direct structural analogue for this bill's approach.
