SBIR Grants from Department of Energy (DOE)
Researched by the BidStride Research Team
Agency overview
DOE SBIR supports innovation across the full energy spectrum: nuclear, fossil, renewables, grid modernization, energy efficiency, and advanced materials. DOE runs four SBIR solicitations per year through its Office of Science and applied energy programs. Many DOE SBIR awardees gain access to the 17 national laboratories (Argonne, Oak Ridge, NREL, etc.) for collaborative R&D — a significant competitive advantage in hardware-intensive energy technology development.
Award details
Phase 1 — Feasibility
Typical Award Amount
$200,000
Duration
9 months
Phase 1 establishes the technical merit and feasibility of the proposed R&D. The deliverable is a feasibility report and prototype demonstration where applicable.
Phase 2 — Full R&D
Typical Award Amount
$1,100,000
Duration
24 months
Phase 2 funds the primary R&D effort to develop the technology to a commercializable or deployable state. Only Phase 1 awardees (or those who meet equivalent requirements) may apply.
Research topic areas
Department of Energy SBIR solicitations consistently address the following research areas. Specific topics vary by solicitation — check the current open solicitation for exact topic descriptions and technical points of contact.
Solicitation cycle
4 per year — January, April, July, and October windows
Solicitation windows open and close on a defined schedule. Applications submitted after the close date are not accepted. Set a calendar reminder at least 6 weeks before the close date — a well-written SBIR application typically takes 60–90 hours of preparation for a first-time applicant.

- 1
Confirm eligibility
Your company must be a for-profit U.S. small business with fewer than 500 employees. The principal investigator must spend at least 51% of their time on the project. More than 50% of the company must be owned by U.S. citizens or permanent residents.

Register in SAM.gov
All SBIR applicants must have an active SAM.gov registration. Registration can take 1–3 weeks. Apply early — the government cannot issue payment on an SBIR award without an active SAM.gov registration.

Review open DOE solicitations
Visit https://science.osti.gov/sbir to see currently open solicitations. Read topic descriptions carefully — each topic has a Technical Point of Contact (TPOC) you can contact with technical questions before submitting.
- 4
Contact the TPOC
Each topic lists a Technical Point of Contact. Email them with a 2-3 sentence summary of your approach before writing your full proposal. TPOCs can tell you whether your company's approach aligns with what the agency is looking for — this step alone doubles your success rate.

Submit through SBIR.gov or the agency portal
DOE SBIR applications are submitted through the agency's designated portal. Most DoD applications go through SBIR.gov. NIH uses ASSIST (grants.nih.gov). NSF uses Research.gov. Check the solicitation for the correct submission system.
Frequently asked questions about DOE SBIR
Yes. DOE actively encourages SBIR awardees to partner with national laboratories through its SBIR/STTR Voucher program and collaborative research agreements. Lab partnerships provide equipment, facilities, and expertise that small companies cannot replicate independently.
DOE SBIR Phase 1 is one of the best non-dilutive funding sources for pre-seed clean energy companies. DOE's SBIR program is separate from Loan Programs Office (LPO) financing — SBIR is grants-based, not debt.
Phase IIB is a DOE-specific follow-on mechanism that provides up to $3 million in additional Phase 2 funding, contingent on the company securing matching private investment. It is designed to bridge the gap between R&D completion and commercial scale-up.
Yes. DOE consistently prioritizes grid-scale storage, lithium-ion alternatives, solid-state batteries, and long-duration energy storage in its SBIR solicitations, reflecting its broader energy transition mandate.
