Why It Matters

The House Science, Space, and Technology Committee advanced three bipartisan research and energy bills on May 20, marking a rare moment of cross-aisle productivity. But beneath the cooperative surface, Ranking Member Rep. Zoe Lofgren (D-CA-18) opened the Full Committee Markup with a pointed complaint about Democratic bills being sidelined, putting committee chair Rep. Brian Babin (R-TX-36) on notice even as the gavel came down on three unanimous voice votes.

The Big Picture

The committee considered H.R. 8748, the Surface Transportation Research and Development Act of 2026; H.R. 8790, the Next Generation Geothermal Research and Development Act; and H.R. 7129, the Water Power Research and Development Reauthorization Act.

The Infrastructure Investment and Jobs Act's surface transportation authorizations expire in September 2026, and the Trump administration has proposed steep cuts to Department of Energy clean energy programs, including a reduction in geothermal funding from $487.9 million to $150 million.

All three bills push back against that trajectory, directing federal R&D investment in areas the administration has otherwise sought to trim. Geothermal, notably, has emerged as a rare clean energy priority for the Trump White House, framed around its compatibility with oil and gas drilling technology.

What They're Saying

Lofgren's opening statement was measured but pointed. She commended Babin for his bipartisanship, then immediately noted that at least seven Democratic draft bills had "languished for a month or longer" without feedback or cosponsors. "I hope, mister chairman, you can understand our frustration," she said. Babin did not respond directly to the criticism.

Sykes, the Democratic co-lead on H.R. 8748, used her time to press on rail safety, invoking East Palestine as a moral obligation. Her remarks carried emotional weight. She also noted that a Transportation and Infrastructure Committee markup was scheduled the following day, suggesting the Science Committee's rail safety provisions were part of a larger, coordinated push.

On geothermal, Harrigan and Rep. Andrea Salinas (D-OR-6) offered a model of bipartisan collaboration, trading thanks and co-leading both the bill and an amendment directing the Department of Energy to include supercritical geothermal conditions in its FORGE research sites. Salinas framed the bill in climate terms; Harrigan framed it as energy dominance. Both got what they wanted.

Two amendments were withdrawn rather than forced to a vote. Salinas pulled a proposal to create a task force on 6PPD, a tire chemical toxic to coho salmon, saying she was "deeply disappointed that there is no path forward for this common sense amendment today." Babin responded that, as an avid salmon fisherman, he would work with her before the bill reached the floor. Rep. Matt Van Epps (R-TN-7) similarly withdrew a geothermal amendment targeting high-load-factor facilities, citing "differing views" among members, a diplomatic retreat that avoided a recorded intraparty division.

Political Stakes

The markup produced real legislative wins, but they come with strings. Babin's own amendment to H.R. 7129 reduced the bill's authorization levels to match current FY2026 appropriated levels, effectively writing the Trump administration's water power funding cuts into statute. That move insulates the bill from White House opposition but also means any future appropriation above those levels would require new authorization. Democrats who support the underlying bill may find themselves in the awkward position of having helped ratify cuts they opposed.

For Sykes, the markup is a partial victory. H.R. 8748 reauthorizes the Rail Cooperative Research Program and directs it toward freight safety and hazardous materials research. But her broader call for corporate accountability and labor protections in rail safety remains unaddressed. She noted she has introduced separate bipartisan legislation, the Reducing Accidents in Locomotive Act, and invited colleagues to join.

Rep. Vince Fong (R-CA-20), who introduced H.R. 8748 just eight days before the markup, added a legislative credential in a competitive California district with major freight infrastructure. Rep. Suzanne Bonamici (D-OR-1), who introduced H.R. 7129 in January and saw it advance through a Republican-chaired committee, posted after the vote that she hoped the bill would come to the House floor soon.

Rep. Christian Menefee (D-TX-18) offered the markup's most urgent framing on water power, arguing that Texas needs $174 billion over the next fifty years just to keep water flowing, a figure that more than doubled in four years. "More than 65 percent of Texas was in drought last week," he said, linking hydropower and marine energy directly to water scarcity and data center demand. The argument reframed a clean energy bill as a water security bill, a reframe with potential appeal across party lines in drought-affected states.

The bills were passed by voice vote, but no Senate companion legislation has been identified for any of the three measures. The Senate Energy and Natural Resources Committee, chaired by Sen. Mike Lee (R-UT), would need to act for any of these bills to reach the president's desk. The geothermal bill faces an additional jurisdictional hurdle: H.R. 8790 was also referred to the House Natural Resources Committee, which may need to act or waive jurisdiction before a floor vote can proceed.

Lofgren's procedural grievance also hangs over the committee's bipartisan reputation. She noted that the markup featured only the fourth Democratic-led bill considered in Congress, now three-quarters complete. That imbalance may grow harder to manage as members look toward the 2026 elections.

What's Next

All three bills were ordered favorably reported as amended. Members have two calendar days to submit supplemental, minority, or additional views. The surface transportation bill feeds into the broader BUILD America 250 Act reauthorization process, with the September 2026 IIJA expiration as a hard deadline. The geothermal and water power bills will need Senate action to advance further.

The Bottom Line

The Science Committee markup moved three bipartisan research bills forward while exposing a simmering Democratic frustration over agenda control that could complicate the committee's bipartisan brand heading into an election year.
