ARPA-E IGNIITE

ARPA-E IGNIITE 2026 sits under the Advanced Research Projects Agency – Energy and is listed as an active U.S. grant route for innovative energy technology aimed at small businesses. The programme is open to for-profit applicants registered in the United States, and it runs on a rolling basis rather than a fixed round calendar. Award sizes range from $500,000 to $10 million. The eligibility profile keeps the focus on commercial energy teams rather than nonprofits or individuals. Geography is U.S.-only, and the proposal path is framed around energy innovation rather than a single thematic subfield. That makes it a broad entry point for small companies with a credible technical edge and a plan to move quickly. Because the cycle is rolling and no formal round count is listed, the main fit question is whether the project can benefit from a substantial federal grant and still read as a small-business effort. Teams with a strong energy concept and a clear market or deployment story are the best match.
