DOE Funding for Energy Research: FOAs, National Labs, and the ARPA-E Fast Track

How DOE Research Funding Is Structured

The Department of Energy funds research through a layered system that confuses first-time applicants. Unlike NIH, which runs a single peer review apparatus, DOE distributes funding across multiple semi-autonomous offices, each with its own application portal, review process, and programmatic priorities. Understanding this structure is the prerequisite for winning DOE awards.

The Office of Science (SC) is the largest funder of basic physical sciences research in the United States, investing roughly $8.1 billion annually across six program offices: Advanced Scientific Computing Research (ASCR), Basic Energy Sciences (BES), Biological and Environmental Research (BER), Fusion Energy Sciences (FES), High Energy Physics (HEP), and Nuclear Physics (NP). These offices fund university researchers, national laboratory staff, and multi-institutional collaborations through competitive Funding Opportunity Announcements.

The Office of Clean Energy, Manufacturing, and Energy Innovation (CMEI) — formerly the Office of Energy Efficiency and Renewable Energy (EERE) — funds applied research and demonstration projects in solar, wind, geothermal, hydrogen, buildings, vehicles, and advanced manufacturing. CMEI awards skew toward technology readiness levels 3 through 7 and frequently require cost-sharing.

The Advanced Research Projects Agency–Energy (ARPA-E) operates as DOE's high-risk, high-reward arm, funding transformational energy technologies that are too early for private investment but too applied for the Office of Science. ARPA-E awards are typically $1 million to $10 million over three years.

The Office of Fossil Energy and Carbon Management (FECM), the Office of Nuclear Energy (NE), and the Office of Electricity (OE) each run their own FOA programs focused on their respective technology domains. The FY 2026 budget signals strong investment in nuclear energy ($3.1 billion to the Office of Nuclear Energy), fusion ($134 million in new collaborative awards), and critical minerals.

The Office of Science FOA Process

Finding the Right FOA

The Office of Science publishes its primary solicitation — the annual Continuation of Solicitation for the Office of Science Financial Assistance Program — as an umbrella FOA (e.g., DE-FOA-0003600 for FY 2026) that remains open throughout the fiscal year. This umbrella FOA covers all six program offices and accepts proposals in any area within the Office of Science mission. Individual program offices also release targeted FOAs for specific research priorities, early-career awards, and collaborative initiatives.

Monitor three sources simultaneously: the Office of Science grants page at science.osti.gov/grants/FOAs/Open, the Portfolio Analysis and Management System (PAMS) at pamspublic.science.energy.gov, and Grants.gov. Targeted FOAs with firm deadlines appear first on PAMS, sometimes weeks before they post to Grants.gov.

Pre-Applications and Letters of Intent

Most Office of Science FOAs require or strongly encourage a pre-application or letter of intent (LOI) before the full proposal. This is not optional guidance — for many targeted FOAs, failing to submit a pre-application by the stated deadline disqualifies your full proposal.

Pre-applications are submitted through PAMS. The typical pre-application is two to four pages and includes the project title, PI information, a brief technical description, and the specific program office and research area you are targeting. The program manager reviews pre-applications and sends either an "encouraged" or "discouraged" response. An "encouraged" response does not guarantee funding but confirms your concept falls within the FOA scope. A "discouraged" response saves you weeks of proposal preparation.

Submit pre-applications early. Program managers at DOE read every one, and the feedback is substantive. If your concept sits at the boundary between two program offices — say, between BES and BER for bio-inspired energy materials — the pre-application response will clarify which office should receive your full proposal.

Writing the Full Proposal

Office of Science proposals are submitted through PAMS and follow a structured format specified in the FOA. The core components include a project narrative (typically 15 to 25 pages depending on the FOA), budget justification, biographical sketches, current and pending support, facilities and equipment description, data management plan, and a Promoting Inclusive and Equitable Research (PIER) Plan.

The project narrative is where proposals succeed or fail. DOE merit review evaluates three primary criteria:

Scientific and Technical Merit. Reviewers assess the quality and originality of the proposed research, its relevance to DOE's mission, and the likelihood of achieving valuable results. Vague claims about advancing the field are not persuasive. State specifically what scientific question you will answer and why the answer matters for energy science.

Appropriateness of Method or Approach. The review panel evaluates whether your technical approach is logically sound and feasible within the proposed timeline and budget. Include preliminary data or proof-of-concept results when possible. DOE reviewers are domain experts who will scrutinize your methodology at a technical level comparable to peer review at top journals.

Competency of Personnel and Adequacy of Resources. Reviewers examine the PI's track record, the team's collective expertise, and whether the proposed facilities and equipment are sufficient. If your project requires access to a DOE user facility — a synchrotron, neutron source, or supercomputer — describe your existing allocation or your plan to obtain one.

The PIER Plan

Beginning in FY 2023, all Office of Science FOAs require a Promoting Inclusive and Equitable Research (PIER) Plan as an appendix. The PIER Plan describes how you will promote diversity, equity, inclusion, and accessibility within your research project. Reviewers evaluate it as part of the merit review. Treat this as a substantive component, not a checkbox. Describe concrete activities: mentoring plans for trainees from underrepresented groups, partnerships with minority-serving institutions, accessible communication of results, or inclusive team-building practices.

Budget Considerations

Office of Science awards for individual investigator grants typically range from $150,000 to $500,000 per year for two to three years. Multi-investigator and center-scale awards can reach $2 million to $5 million annually. Cost sharing is not required for basic research awards under the Office of Science, per the exclusion in Section 988 of the Energy Policy Act of 2005. This is a meaningful advantage over CMEI and ARPA-E awards, which frequently require 20 to 50 percent cost share.

Indirect cost rates follow your institution's negotiated rate with the cognizant federal agency. DOE does not impose a cap on indirect costs for Office of Science awards, though reviewers will flag budgets where indirect costs consume a disproportionate share relative to the direct research activities.

Partnering with National Laboratories

DOE operates 17 national laboratories with $18 billion in combined annual budgets. These labs house unique experimental facilities — particle accelerators, light sources, nanoscience centers, supercomputers — that university researchers cannot replicate. Partnering with a national lab strengthens your DOE proposal and gives you access to capabilities that define the frontier of energy research.

Three Partnership Mechanisms

Cooperative Research and Development Agreement (CRADA). A CRADA is a joint research agreement where both the external partner and the lab contribute resources — funding, labor, equipment, or facilities. CRADAs are the most common mechanism for collaborative R&D. The external partner can negotiate intellectual property terms, including exclusive licenses to inventions made under the agreement. CRADAs work well when both parties bring complementary expertise and the research agenda overlaps.

Strategic Partnership Projects (SPP). Formerly called Work for Others (WFO), an SPP is a fee-for-service arrangement where the external partner pays the lab to perform a defined scope of work. The lab's unique facilities or expertise drive most SPP agreements. Unlike CRADAs, SPP agreements do not involve joint research — the lab executes the work on behalf of the partner. Intellectual property generated under an SPP typically belongs to the lab, with the partner receiving a nonexclusive license.

User Facility Access. DOE's Office of Science operates 28 scientific user facilities, including five light sources, two neutron sources, five Nanoscale Science Research Centers, and the Leadership Computing Facilities at Oak Ridge and Argonne. Access is granted through a peer-reviewed proposal process separate from the funding FOA. General user proposals are typically six months to one year in duration and are free of charge for research that will be published in the open literature.

How to Initiate a Lab Partnership

Contact the lab's technology transfer or partnerships office directly. Every national lab maintains a partnerships website listing points of contact by technical area. For CRADAs and SPPs, the process starts with a statement of work and a negotiation over terms, which typically takes three to six months. For user facility access, submit a proposal through the facility's online portal during an open call — most facilities accept proposals on a rolling or semi-annual basis.

In your DOE proposal, a letter of intent or support from a national lab collaborator signals that the partnership is real, not aspirational. Name the specific facility, the lab scientist who will participate, and the scope of their contribution. Reviewers at DOE know their own labs well and can immediately assess whether the claimed partnership adds genuine value.

EPSCoR: Lab Partnerships for Under-Resourced States

The DOE Established Program to Stimulate Competitive Research (EPSCoR) funds researchers in 28 designated states and territories to build partnerships with national laboratories. Awards range from $600,000 to $1 million over four years. EPSCoR proposals require a named national lab collaborator and a plan for building long-term research capacity at the applicant institution. If your university is in an EPSCoR-eligible state, this program offers a structured on-ramp to the national lab ecosystem. Recent rounds have funded approximately 30 to 35 awards totaling $35 million.

ARPA-E: The High-Risk, High-Reward Track

How ARPA-E Differs from the Office of Science

ARPA-E funds technology development, not basic research. The agency seeks concepts that, if successful, would create entirely new energy technology categories or displace incumbent technologies at scale. ARPA-E program directors define specific technical challenges and assemble focused programs around them. The agency tolerates failure — its model assumes that a portfolio of high-risk bets will yield a small number of transformative successes.

ARPA-E awards typically range from $500,000 to $10 million over two to four years. The agency has funded over 1,300 projects since its founding in 2009, with a cumulative budget that has fluctuated between $400 million and $460 million annually. The FY 2026 budget proposes $414 million.

Types of ARPA-E Solicitations

Focused Programs. ARPA-E's primary mechanism. A program director identifies a specific energy technology challenge — grid-scale energy storage, direct air capture, advanced nuclear materials — and designs a program with defined technical targets. Focused programs typically fund 10 to 30 projects each. ARPA-E plans to release up to four new focused solicitations in FY 2026.

OPEN Solicitations. Released every three years (most recently OPEN 2024), OPEN solicitations accept proposals across all energy technology areas without thematic restrictions. OPEN programs are ARPA-E's broadest and most competitive funding vehicle. Historical OPEN rounds have received thousands of concept papers and funded roughly 2 percent of applicants.

SCALEUP. The Seeding Critical Advances for Leading Energy technologies with Untapped Potential program funds the commercialization of previously ARPA-E-funded technologies. SCALEUP awards are substantial — $63.5 million across four projects in one recent round, with individual awards reaching $20 million. Eligibility is restricted to current or former ARPA-E performers whose technologies have demonstrated technical feasibility but need pre-commercial scaling.

The ARPA-E Application Process

ARPA-E uses a two-stage process managed through the ARPA-E eXCHANGE portal (arpa-e-foa.energy.gov).

Stage 1: Concept Paper. The concept paper is four to eight pages (varies by FOA) and is your most important submission. ARPA-E program directors and technical reviewers use the concept paper to screen for transformative potential. Roughly 10 to 20 percent of concept papers are invited to submit full applications.

Two criteria carry equal weight in concept paper review:

• Impact of the Proposed Technology (50%). Reviewers evaluate whether the technology, if successful, would be truly transformative and disruptive. They assess mission alignment, awareness of competing technologies, and the magnitude of the potential energy impact. Incremental improvements over existing technology score poorly.

• Overall Scientific and Technical Merit (50%). Reviewers assess feasibility, the clarity of the technical approach, whether outcomes are well-defined, and whether the team has the demonstrated capabilities to execute.

Use figures strategically in the concept paper. A well-designed diagram communicating your technology concept and its performance advantage is more effective than a page of text. But do not shrink figures to the point of unreadability — reviewers print these documents.

Stage 2: Full Application. Invited full applications are typically 20 to 30 pages and include a detailed technical plan, management approach, milestones with quantitative go/no-go criteria, budget, and commercialization plan. ARPA-E assigns a Technology-to-Market (T2M) advisor to every funded project, and your full application should demonstrate awareness of the commercialization pathway.

Writing a Competitive ARPA-E Concept Paper

State the problem in energy terms, not academic terms. ARPA-E does not fund research for knowledge's sake. Your opening paragraph should quantify the energy challenge: the size of the addressable market, the performance gap between current technology and what is needed, or the cost target that would enable deployment at scale.

Define your technical innovation in one clear sentence. If you cannot articulate what is new in a single sentence, the concept is either not novel enough or not yet well-defined.

Quantify your targets. ARPA-E programs are built around measurable performance metrics. State the specific energy density, efficiency, cost per kilowatt-hour, or other quantitative target you will achieve and how it compares to the state of the art.

Address the "why now" question. Reviewers want to understand what recent scientific advance, material discovery, or computational capability makes your approach feasible today when it was not five years ago.

DOE SBIR and STTR Programs

DOE's SBIR/STTR program is administered by the Office of Science and funds small businesses developing energy-related technologies across all DOE mission areas. The program releases FOAs for Phase I and Phase II each fiscal year through the SBIR/STTR eXCHANGE portal.

Phase Structure and Award Amounts

Phase I explores technical feasibility. Awards are up to $200,000 (topic-dependent) over a nine-month period. The Phase I proposal must demonstrate that the concept is scientifically sound and that the small business has the capability to execute the research.

Phase II funds expanded R&D based on Phase I results. Awards are up to $1,100,000 over two years. Only companies that have received a DOE Phase I award are eligible for Phase II. The Phase II proposal requires a commercialization plan describing the path from R&D to market.

Phase III is the commercialization stage. DOE does not provide Phase III SBIR funding — the company is expected to attract private investment, non-SBIR federal contracts, or revenue to continue development.

DOE SBIR Topic Selection

DOE SBIR topics are written by program managers across all DOE offices and national laboratories. Each topic describes a specific technical challenge, the current state of the art, and the desired innovation. Topics span the full range of DOE's mission: nuclear physics instrumentation, grid cybersecurity, advanced materials for extreme environments, environmental remediation technologies, and more.

Read topics literally. If the topic asks for a sensor that operates at 800°C and your sensor works at 600°C, your proposal is non-responsive regardless of how innovative the underlying technology is. Contact the topic author during the pre-release period to confirm that your concept falls within the topic scope.

Program Status Note

The SBIR/STTR programs lapsed on September 30, 2025, when Congress failed to pass a reauthorization before the deadline. The House passed the SBIR/STTR Reauthorization Act on March 17, 2026, with a 345-41 vote, unlocking approximately $6 billion in frozen small business R&D funding. Agencies are resuming solicitations, though the timeline for new DOE SBIR FOAs is still being finalized. Monitor science.osti.gov/sbir for updates.

DOE Proposal Writing: Tactical Advice

Align with DOE's Current Priorities

DOE's FY 2026 budget signals clear priority areas: nuclear energy and advanced reactors, fusion energy, artificial intelligence and high-performance computing, critical minerals, and grid resilience. Proposals that align with these priorities have a structural advantage. This does not mean abandoning your research program — it means framing your work in terms that connect to DOE's stated mission needs.

The current administration has emphasized "energy dominance" as an organizing principle, with increased funding for nuclear ($3.1 billion), fossil energy ($595 million for FECM), and national security applications. Office of Science funding remains strong at approximately $8 billion, with fusion energy sciences and AI/computing receiving particular attention.

Use DOE Vocabulary

Every federal agency has its own language. DOE proposals should reference Technology Readiness Levels (TRLs), critical performance parameters, go/no-go decision points, and techno-economic analysis. For ARPA-E, use language about "disruptive potential," "transformational impact," and "state-of-the-art" benchmarks. For the Office of Science, emphasize "scientific impact," "intellectual merit," and "mission relevance."

Leverage Preliminary Data from User Facilities

If you have conducted experiments at a DOE user facility, feature those results prominently. Data collected at Argonne's Advanced Photon Source, Oak Ridge's Spallation Neutron Source, or SLAC's Linac Coherent Light Source carries implicit credibility with DOE reviewers. It demonstrates that you already operate within the DOE research ecosystem and can productively use national infrastructure.

Budget for National Lab Subcontracts

When partnering with a national lab, include their costs as a subcontract in your budget. National lab personnel charge full cost recovery rates that include overhead, which can be significantly higher than university rates. Budget realistically — underestimating lab costs is a common mistake that creates problems during award negotiation.

Understand the Review Timeline

Office of Science proposals submitted under the umbrella FOA are reviewed on a rolling basis, with review panels convened periodically throughout the fiscal year. Targeted FOAs have fixed deadlines, and reviews typically occur two to four months after submission. Award decisions follow one to three months after review. From submission to award, expect six to nine months for most Office of Science grants.

ARPA-E moves faster. Concept paper decisions arrive within eight to twelve weeks of the deadline. Full application reviews take an additional two to three months. Total time from concept paper submission to award can be as short as six months, which is unusually rapid for federal funding.

Frequently Asked Questions

Can a university PI apply directly to ARPA-E, or is it only for companies?

Universities are eligible ARPA-E applicants. Roughly 30 percent of ARPA-E awards go to universities, with the remainder split between small businesses, large companies, and national labs. However, ARPA-E expects all performers — including universities — to articulate a commercialization pathway. A university PI applying to ARPA-E should identify an industry partner or describe a licensing strategy as part of the full application.

What is the difference between applying to the Office of Science umbrella FOA versus a targeted FOA?

The umbrella FOA (e.g., DE-FOA-0003600) accepts proposals in any area within the Office of Science mission and remains open year-round. Targeted FOAs address specific research priorities with firm deadlines and dedicated review panels. If a targeted FOA matches your research, apply there — it signals that DOE has allocated funding for that specific area. If no targeted FOA fits, the umbrella FOA is your path, but be aware that competition is diffuse and funding depends on program office budgets.

How do I get access to a DOE national lab user facility if I do not already have a relationship?

Start with the facility's website and submit a general user proposal during the next open call. Most facilities review proposals two to four times per year. For beam time at light sources or neutron facilities, proposals are evaluated on scientific merit by an external review panel. Approved proposals receive beam time at no cost if you agree to publish your results. Contact the facility's user office for guidance on proposal preparation — they actively want to expand their user base.

Does DOE require cost sharing for research grants?

It depends on the program. Office of Science basic research awards are exempt from cost sharing under the Energy Policy Act of 2005. CMEI and ARPA-E awards frequently require cost sharing of 20 to 50 percent, depending on the FOA and the applicant type (industry partners typically face higher cost-share requirements than universities). DOE SBIR Phase I and Phase II awards do not require cost sharing.

What is the DOE Early Career Research Program, and who is eligible?

The Early Career Research Program provides five years of funding (up to $500,000 per year for university researchers, up to $1 million per year for national lab scientists) to support the development of individual research programs by outstanding scientists early in their careers. Eligibility requires an untenured, tenure-track position at a U.S. academic institution or a full-time position at a DOE national lab, with a PhD received within the past 10 years. The program is highly competitive, with roughly a 15 to 20 percent success rate, and covers all six Office of Science program areas.

Granted helps research teams identify the right DOE funding opportunity and build competitive proposals by matching your technical focus to the program office, FOA, and review criteria most likely to support your work.
