Agency Overview:

The Advanced Research Projects Agency – Energy (ARPA-E), an organization within the Department of Energy (DOE), is chartered by Congress in the America COMPETES Act of 2007 (P.L. 110-69), as amended by the America COMPETES Reauthorization Act of 2010 (P.L. 111-358), as further amended by the Energy Act of 2020 (P.L. 116-260).

ARPA-E issues this Notice of Funding Opportunity (NOFO) under its authorizing statute codified at 42 U.S.C. § 16538. The NOFO and any cooperative agreements or grants made under this NOFO are subject to 2 C.F.R. Part 200 as supplemented by 2 C.F.R. Part 910.

ARPA-E funds research on, and the development of, transformative science and technology solutions to address the energy and environmental missions of the Department. The agency focuses on technologies that can be meaningfully advanced with a modest investment over a defined period of time in order to catalyze the translation from scientific discovery to early-stage technology. For the latest news and information about ARPA-E, its programs and the research projects currently supported, see: http://arpa-e.energy.gov/.

ARPA-E funds transformational research. Existing energy technologies generally progress on established “learning curves” where refinements to a technology and the economies of scale that accrue as manufacturing and distribution develop drive improvements to the cost/performance metric in a gradual fashion. This continual improvement of a technology is important to its increased commercial deployment and is appropriately the focus of the private sector or the applied technology offices within DOE. In contrast, ARPA-E supports transformative research that has the potential to create fundamentally new learning curves. ARPA-E technology projects typically start with cost/performance estimates well above the level of an incumbent technology. Given the high risk inherent in these projects, many will fail to progress, but some may succeed in generating a new learning curve with a projected cost/performance metric that is significantly better than that of the incumbent technology. ARPA-E will provide support at the highest funding level only for submissions with significant technology risk, aggressive timetables, and careful management and mitigation of the associated risks.

ARPA-E funds technology with the potential to be disruptive in the marketplace. The mere creation of a new learning curve does not ensure market penetration. Rather, the ultimate value of a technology is determined by the marketplace, and impactful technologies ultimately become disruptive – that is, they are widely adopted and displace existing technologies from the marketplace or create entirely new markets. ARPA-E understands that definitive proof of market disruption takes time, particularly for energy technologies. Therefore, ARPA-E funds the development of technologies that, if technically successful, have clear disruptive potential, e.g., by demonstrating capability for manufacturing at competitive cost and deployment at scale.

ARPA-E funds applied research and development (R&D). The Office of Management and Budget defines “applied research” as an “original investigation undertaken in order to acquire new knowledge…directed primarily towards a specific practical aim or objective” and defines “experimental development” as “creative and systematic work, drawing on knowledge gained from research and practical experience, which is directed at producing new products or processes or improving existing products or processes.”

Applicants interested in receiving financial assistance for basic research (defined by the Office of Management and Budget as “experimental or theoretical work undertaken primarily to acquire new knowledge of the underlying foundations of phenomena and observable facts”) should contact the DOE’s Office of Science (http://science.energy.gov/). Office of Science national scientific user facilities (http://science.energy.gov/user-facilities/) are open to all researchers, including ARPA-E Applicants and awardees. These facilities provide advanced tools of modern science including accelerators, colliders, supercomputers, light sources and neutron sources, as well as facilities for studying the nanoworld, the environment, and the atmosphere. Projects focused on early-stage R&D for the improvement of technology along defined roadmaps may be more appropriate for support through the DOE applied energy offices including: the Office of Critical Minerals and Energy Innovation (CMEI) (https://www.energy.gov/cmei/office-critical-minerals-and-energy-innovation), the Hydrogen and Geothermal Energy Office (https://www.energy.gov/hgeo/hydrocarbons-and-geothermal-energy-office), the Office of Nuclear Energy (http://www.energy.gov/ne/office-nuclear-energy), and the Office of Electricity (https://www.energy.gov/oe/office-electricity).

ARPA-E encourages submissions stemming from ideas that still require proof-of-concept R&D efforts as well as those for which some proof-of-concept demonstration already exists. Submissions can propose a project with the end deliverable being an extremely creative, but partial solution.

Guides
  • Proposal submission checklist

    A pre-submission checklist for research proposals: solicitation review, internal routing, budget, compliance, and sponsor-system steps to hit the deadline cleanly.

  • Direct vs. indirect costs

    The difference between direct and indirect costs on research grants, with examples of each, the gray areas like administrative salaries, and how indirect costs are calculated from your F&A rate.

  • Reading your Notice of Award

    The parts of a Notice of Award that determine what you can spend, when, and what needs prior approval, plus the terms that cause disallowed costs if missed.

Templates
  • Grant Budget Template

    A five-year research grant budget in Excel that calculates fringe, the NIH salary cap, the MTDC base, and F&A automatically.

  • Budget Justification Template

    A free budget justification (budget narrative) template for research grants, organized by the federal R&R budget categories, with example language for personnel, fringe, equipment, travel, other direct costs, subawards, and F&A.

  • Grant Letter of Intent Template

    A free grant letter of intent (LOI) template with two versions: the short NIH letter of intent requested in many funding opportunities, and a foundation LOI that pitches the project before a full proposal.

  • Letter of Support Template for Grant Applications

    A free letter of support template for NIH and other research grant applications, with collaborator and consultant versions, what NIH asks letters to include, and how NIH's move to letters of collaboration affects them.

Calculators and systems
  • F&A & MTDC calculator

    Build the Modified Total Direct Cost base, apply your F&A rate, and see total direct costs, indirect costs, and the full award total, with the usual MTDC exclusions handled.

  • Grant burn rate

    Compare the share of a grant spent and encumbered with the share of the award period elapsed, see the average monthly burn, the monthly spend needed to finish on budget, and the projected run-out date.

  • DOE PAMS
