EPA SBIR Phase II

EPA SBIR Phase II sits under the Environmental Protection Agency's SBIR portfolio and is limited to businesses that already won EPA Phase I support. It provides up to $400,000 over two years to move an EPA-backed concept toward a market-ready environmental technology, with an additional $100,000 commercialization option tied to third-party investment. The route is invitation-only and open only to U.S. for-profit businesses. The record caps the award at $400,000, places the work in the United States, and points to prototype-to-demonstration development rather than open-ended research. FY24-25 activity totaled about $2.8 million across seven businesses. EPA uses this stage to extend proven Phase I work instead of reopening early technical risk, so the best fit is a company with a clear environmental use case, outside capital, and evidence that the first phase has already cleared the science hurdle. The program is active and moves by rolling invitation. It stays limited to prior Phase I winners and does not open a fresh competition.
