The Department of Energy (DOE) is offering funding opportunities through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs for Fiscal Year 2024. This funding is made available under the statutory authority of the U. S. Department of Energy Organization Act and the Small Business Act, with additional support from the Bipartisan Infrastructure Law (BIL). The primary goal of these programs is to support small businesses in conducting research and development (R&D) that has the potential for commercialization and aligns with DOE's mission-related scientific or engineering challenges. The SBIR/STTR programs aim to increase private sector commercialization of technology, stimulate technological innovation, and encourage participation by women-owned and minority-owned small businesses. Applicants can apply for either Phase I or Fast-Track grants. Phase I grants focus on evaluating the scientific or technical merit and feasibility of ideas, with maximum award sizes of $200,000 or $250,000, depending on the topic. Fast-Track grants combine Phase I and Phase II funding into a single application, with maximum award sizes of $1,300,000 or $1,850,000. The period of performance for Phase I grants will not exceed 12 months, while Fast-Track grants can extend up to 36 months. Only awardees of Phase I grants under this FOA are eligible to submit a Phase II application in the subsequent fiscal year. The DOE anticipates making approximately 260 awards, with an estimated total funding of $65,000,000. The programs also emphasize diversity, equity, inclusion, and accessibility, encouraging participation from socially and economically disadvantaged groups.
