Next-Generation Geothermal Research and Development Act
Summary
The Next-Generation Geothermal Research and Development Act (HR8790) was reported out of committee on May 20, 2026, awaiting floor action. The bill authorizes DOE R&D for advanced geothermal systems, including closed-loop and supercritical technologies, but does not appropriate specific funding. This creates a structural tailwind for geothermal equipment suppliers and developers, though actual spending requires separate appropriations.

Key Takeaways
- 1.HR8790 authorizes DOE R&D for next-generation geothermal but does not appropriate funds; actual spending requires separate appropriations.
- 2.The bill targets closed-loop and supercritical geothermal systems, expanding the technology scope beyond traditional hydrothermal.
- 3.Public company beneficiaries are diversified: GEV (equipment), NEE (developer), DUK (regulated utility) — no pure-play geothermal public companies exist.
Market Implications
The bill's passage out of committee is a procedural step with limited immediate market impact. For retail investors, the key signal is the expansion of DOE's geothermal R&D mandate to include closed-loop and supercritical systems, which could open new revenue streams for equipment providers like $GEV. However, without a funding authorization, the market should not price in significant revenue until appropriations are passed. $NEE and $DUK may benefit from a new baseload renewable option, but geothermal remains a small fraction of their generation mix.

What the bill does
Authorization of R&D, demonstration, and commercial application activities for next-generation geothermal and closed-loop geothermal systems, including machine learning integration for resource characterization.
Who must act
U.S. Department of Energy (DOE) Geothermal Technologies Office
What happens
DOE will issue grants and cooperative agreements for geothermal technology development, including closed-loop and supercritical systems, expanding the addressable market for geothermal equipment and services.
Stock impact
GEV's GE Vernova segment provides power generation equipment and services; geothermal expansion increases demand for turbines, heat exchangers, and drilling services. GEV's existing geothermal and renewable energy service contracts position it to capture a share of DOE-funded demonstration projects.
What the bill does
Authorization of R&D for next-generation geothermal systems, which can provide baseload renewable power, complementing intermittent wind and solar.
Who must act
U.S. Department of Energy (DOE) Geothermal Technologies Office
What happens
DOE-funded research may reduce the cost and risk of geothermal development, making it a more viable resource for utilities and independent power producers.
Stock impact
NEE's NextEra Energy Resources develops and operates renewable energy projects. Geothermal expansion offers a new baseload renewable resource for NEE's portfolio, diversifying its generation mix and potentially reducing curtailment costs for its wind and solar assets.

Integrating Financial Technology Innovation into Regulatory Frameworks
This executive order directs federal financial regulators to review and streamline regulations that hinder fintech innovation, particularly for small and emerging firms, and requests the Federal Reserve to evaluate expanding access to its payment accounts and services for non-bank and digital asset firms. It aims to reduce barriers to entry and encourage partnerships between fintech firms and traditional financial institutions, with specific deadlines for reviews and reports.
Imposing Sanctions on Those Responsible for Repression in Cuba and for Threats to United States National Security and Foreign Policy
This Executive Order expands the existing national emergency against the Government of Cuba by imposing broad secondary sanctions and asset freezes on foreign persons operating in key sectors of the Cuban economy (energy, defense, metals/mining, financial services, security). It authorizes the Treasury and State Departments to block property and deny entry to individuals and entities involved in repression, corruption, or support for the Cuban government, and empowers Treasury to sanction foreign financial institutions that facilitate transactions for designated persons. The order effectively tightens the U.S. embargo by targeting third-country companies and banks that do business with Cuba.
Presidential Permit: Authorizing Bridger Pipeline Expansion LLC to Construct, Connect, Operate, and Maintain Pipeline Facilities at the International Boundary at Phillips County, Montana, Between the United States and Canada
This Presidential Memorandum grants a permit to Bridger Pipeline Expansion LLC to construct and operate a new 36-inch diameter crude oil and petroleum products pipeline crossing the U.S.-Canada border in Montana. The permit authorizes bidirectional flow and variable throughput capacity without requiring further presidential approval, while maintaining existing regulatory oversight from agencies like PHMSA and reserving the government's right to seize the facilities for national security with compensation.
