What Is the U.S. Department of Energy Office of Science?

Updated

The Office of Science (SC) is the U.S. Department of Energy's program office for fundamental research, and it describes itself as the nation's largest supporter of basic research in the physical sciences. If you are a researcher, university, national laboratory, or company trying to understand where DOE basic-science funding comes from and which program fits your work, SC is the place to start. Its scope runs from computing and physics to biology, fusion, and workforce training, and its funding opportunities are announced publicly on science.osti.gov.

What the Office of Science does

SC supports fundamental scientific research for energy. That framing matters: the work it funds is basic and physical-sciences oriented rather than applied energy deployment or regulation. The office also runs programs aimed at preparing a highly skilled workforce and at connecting small businesses to research funding.

Main research programs

The program structure is the clearest way to figure out whether your topic belongs at SC. Each program covers a distinct research domain:

Program Abbreviation Focus area
Advanced Scientific Computing Research ASCR Computing and computational science
Basic Energy Sciences BES Basic energy-related science
Biological and Environmental Research BER Biological and environmental systems
Fusion Energy Sciences FES Fusion research
High Energy Physics HEP High energy physics
Nuclear Physics NP Nuclear physics
Project Assessment OPA Project assessment

Two additional efforts sit alongside the research programs:

  • Workforce Development for Teachers and Scientists (WDTS) — supports preparation of a highly skilled workforce.
  • Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) — channels funding to small businesses.

If your work is applied rather than fundamental, or fits a mission area outside physical sciences, check whether another DOE office is the better fit before investing time in an SC application.

Types of funding opportunities

SC's announcements show the range of what it funds. Recent examples listed on the site include:

  • Early career awards — the Department of Energy awarded $96 million to 67 early career scientists.
  • Genesis Mission — a graduate fellowship to advance American scientific leadership, plus new Genesis Mission awards to advance super intelligence for science.
  • Quantum — a Request for Application (RFA) for the DOE Quantum Genesis Q Competition.
  • AI and science — an RFA for the Genesis Mission: Transforming Science and Energy with AI.
  • Neutron sources — a Dear Colleague Letter in which FES solicits applications from private companies, universities, and/or national laboratories exploring volumetric neutron sources.

These examples illustrate three different entry points: individual early-career awards, large mission-oriented competitions, and program-specific solicitations such as the FES neutron-source letter.

How to find and pursue funding

  1. Go to the Office of Science site at science.osti.gov.
  2. Open the Funding Opportunities page (linked from the special announcements area) to see current solicitations.
  3. Identify the program whose focus matches your research — for example, FES for fusion or neutron-source work, ASCR for computing.
  4. Read the specific announcement for eligibility and application requirements. Note that some opportunities are open to private companies, universities, and national laboratories, while others target individuals or small businesses.
  5. Prepare your application against the requirements in that announcement, not against a general SC template.

The site's "View All Funding Opportunities" link is the single entry point for current solicitations, so start there rather than searching program pages individually.

Choosing the right track

  • Academic or laboratory researcher in a physical-sciences field → look at the relevant research program (ASCR, BES, BER, FES, HEP, NP) and its solicitations.
  • Early-career scientist → watch for early career award announcements.
  • Small business → SBIR/STTR is the designated route.
  • Educator or workforce program → WDTS is the relevant program.
  • Work tied to AI, quantum, or a named mission → check the Genesis Mission and Quantum Genesis announcements, which have their own RFAs.

One practical caution: eligibility differs by announcement. The FES neutron-source letter, for instance, explicitly invites private companies, universities, and national laboratories, while other calls may be narrower. Confirm eligibility in the specific notice before preparing a submission.
