ARPA-E Survives Proposed 57% Cut but Loses $110M in Energy Research Funding

The Advanced Research Projects Agency-Energy will live to fund another year of high-risk energy research — but with significantly less money than it had before.
Congress set ARPA-E's FY 2026 budget at approximately $350 million, a $110 million reduction from its $460 million FY 2025 level. The cut is painful, but it's a far cry from the Trump administration's original proposal to slash the agency's budget to $200 million — a 57 percent reduction that the Energy Sciences Coalition called a threat to American competitiveness in clean energy technology.
What ARPA-E Funds
ARPA-E backs early-stage energy technologies that are too risky for private capital but too promising to ignore: next-generation batteries, advanced nuclear reactor designs, carbon capture systems, fusion energy concepts, and grid-scale storage solutions. Since its creation in 2009, the agency has funded over 1,500 projects, and its portfolio companies have attracted more than $12 billion in follow-on private investment.
The 24 percent budget reduction means fewer new program solicitations in FY 2026. ARPA-E typically launches 15 to 20 focused programs per year, each with its own competitive solicitation. Expect that number to drop, and expect individual award sizes to tighten.
The Broader DOE Science Picture
ARPA-E's cut stands in contrast to the DOE Office of Science, which received $8.4 billion — a nearly 2 percent increase. Energy efficiency and renewable energy programs landed $3.1 billion. The divergence suggests Congress values DOE's core research portfolio but sees ARPA-E's high-risk mandate as more expendable in tight budget years.
What Clean Energy Innovators Should Do
Small businesses and research teams that rely on ARPA-E funding should diversify their federal funding strategy now. DOE's Office of Science, the SBIR/STTR programs across multiple agencies, and NSF's new Tech Labs initiative all fund overlapping technology areas. State-level clean energy programs — particularly in California, New York, and Massachusetts — offer additional pathways. Tracking opportunities across these sources through Granted helps energy researchers find alternatives as ARPA-E's portfolio contracts.
