ARPA-E OPEN

ARPA-E OPEN sits under the Advanced Research Projects Agency – Energy and is the agency's broad, recurring solicitation for hard-tech energy research. It is a U.S. grant programme with a triennial cycle, currently marked between cycles, and the record points to a next round around Q3 2026. Award sizes run from $500,000 to $10 million, with a median actual award of about $1.48 million. The programme is aimed at U.S. applicants working on energy, climate, and materials problems. It accepts for-profit companies and nonprofits, but not individuals, and it expects at least 20% match funding. The geography is U.S.-only, and the route is built for teams that can pair technical novelty with a credible commercial or deployment case. What separates OPEN from narrower agency solicitations is breadth. The competition is ranked rather than weighted by section, so applicants need a strong overall case across the entire proposal. The field is best suited to projects that can justify a larger check and hold up against comparison with other high-risk energy concepts.
