Small Business Research All-in-One Application Tool

Does your small business need funding to advance clean energy technologies?

If yes, our new All-in-one Application Tool can help. It provides a comprehensive guide for potential applicants to EERE Topics  under the U.S. Department of Energy’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs. If you are new to DOE SBIR, look at our Definitions.

Why two programs? They were established under separate laws with separate eligibility  requirements summarized in Table A1 below.  But the two programs have many similar features—especially the DOE SBIR/STTR programs. DOE runs its SBIR and STTR programs at the same time using the same topics. This video is a detailed overview of the SBIR/STTR programs at DOE.

STTR Minimum Level of Effort Either with Small

Funding begins in Phase I. This is also where the Topics that are used for Phases I, II and III are set. The topic descriptions in the open funding opportunity announcement (FOA) also provide information per topic on the maximum award size, and whether the topic is Fast-Track (combined Phase I and Phase II award). The SBIR and STTR programs in DOE’s Office of Energy Efficiency and Renewable Energy (EERE) strongly align with the EERE’s mission.  See additional details in this All-in-one Tool about EERE’s SBIR/STTR application process.
