ARPA-E funds a wide range of individual technology projects. Typically, these projects are organized into focused technology programs that revolve around a common technical area. All ARPA-E programs and projects are created through a process of rigorous debate over the technical and scientific merits and challenges of potential research areas. ARPA-E Program Directors are constantly exploring potential topics for future program areas.

ARPA-E also issues periodic open funding solicitations for a broader range of projects that do not fall into a single technical area to address the full range of energy-related technologies, as well as targeted funding solicitations aimed at supporting America’s small business innovators.

ARPA-E also funds projects on a rolling basis through "special projects" funding opportunities that are meant to inform potential new program areas for the future.
