The founder's guide
What Are DOE Small Business Vouchers?
DOE Small Business Vouchers (SBV), part of the Department of Energy's Technology-to-Market work, give small clean-energy businesses access to the expertise and specialist equipment of the US national laboratories, NREL, Argonne, Oak Ridge, Sandia, Lawrence Berkeley and others. The value is delivered as lab time and collaboration ($50K to $300K), not as cash in your account.
For a hardware or energy startup, access to national lab-grade facilities without the capital cost can be transformational. One important note: voucher rounds open and close, and the program's status can change, so always verify current openings at the official DOE source before you invest time. Our free check shows whether DOE labs, and every other US grant, fit your startup right now.
Check the current status before applying.DOE voucher opportunities are periodically restructured and re-opened. Confirm what's currently accepting applications via the official DOE / EERE source, then let us match you with everything else you qualify for in parallel.
Vouchers target small US businesses with technology that aligns to DOE's mission areas.
A US small business (typically fewer than 500 employees), with no specific revenue requirement.
Technology in a DOE mission area, energy, climate, grid resilience, advanced manufacturing, or nuclear.
A specific lab need. Applications identify the national lab capability you want to access and the technical problem it will help solve.
An open round. Access depends on a voucher round being open, so timing and current program status matter.
A founder's guide
How DOE Vouchers Work
Vouchers fund a collaboration with a national lab, not a cash grant to your company.
Step 1
Identify the Right Lab & Need
Match your technical challenge to a national lab capability, NREL for solar, wind, and grid; Argonne for batteries and materials; Sandia for grid resilience and cyber. Run the free eligibility checker to see DOE labs alongside other US grants.
Step 2
Apply Through an Open Round
When a round is open, register and apply through the relevant DOE / EERE channel with a short technical description and your chosen lab partner. Always confirm the current status first.
Step 3
Work With the Lab
If selected, you collaborate directly with lab scientists and use their facilities to de-risk your technology, worth $50K to $300K in lab time and expertise you'd otherwise have to fund yourself.

The strongest raises stack multiple non-dilutive programmes. Here are the other US grants you can apply for, all matched in one free eligibility check.
No. The value (typically $50K to $300K) is delivered as access to national lab facilities, equipment, and expertise, not as money in your bank account. For hardware and energy startups, that lab time is often worth far more than an equivalent cash grant.
It varies. DOE voucher opportunities are periodically restructured and re-opened, so always confirm current openings at the official DOE / EERE source before investing time. Our free check helps you act on what's open now, and lines up the other grants you qualify for.
Match the lab to your technology: NREL for solar, wind, and grid; Argonne for batteries and advanced materials; Sandia for grid resilience and cybersecurity; Lawrence Berkeley for building energy and data science.
Yes. Lab vouchers pair naturally with cash R&D grants such as SBIR/STTR and ARPA-E. Use the facilities to de-risk, and the grants to build. Our free check shows everything you qualify for.
The Full Capital Stack
Grants Are Only Part of the Stack
SBIR awards and federal grants cover early-stage R&D, but most US startups need equity capital to scale. The strongest raises combine non-dilutive grants with angel or VC investment.
AngelsPartners is the only platform where a founder can access all three capital pathways in one place: grants (this page), debt financing, and 120,000+ equity investors.
