The innovation programs within the Office of the Deputy Assistant Secretary of Defense for Environment & Energy Resilience harness the latest science and technology to improve the Department’s energy and environmental performance, reduce costs, and advance mission capabilities. These research, demonstration, test, and evaluation programs ensure DoD is prepared to address current and future environmental and energy challenges with cutting-edge research and innovative technologies.

These programs include the Strategic Environmental Research and Development Program (SERDP), the Environmental Security Technology Certification Program (ESTCP), and the Operational Energy – Innovation Directorate (OE-I).


SERDP and ESTCP develop and demonstrate innovative, cost-effective, and sustainable solutions to meet DoD’s environmental and installation energy challenges. SERDP invests across a broad spectrum of research and development, and ESTCP demonstrates and validates technologies for rapid transition. They are independent programs managed by a joint office to accelerate the timeline from innovative concepts to implementation.


The OE-I Directorate provides Joint Force policy, oversight, and program management for emerging operational energy technologies. It leads DoD operational energy communities to provide a common operating picture of OE investments. The Operational Energy Capability Improvement Fund (OECIF) and Operational Energy Prototyping Fund (OEPF) programs develop and prototype technologies that provide tactical overmatch for our warfighters and allies. OECIF and OEPF apply cutting-edge science and technology to developing and demonstrating innovative, cost-effective, supportable energy solutions to meet joint requirements, lower carbon emissions, and maintain freedom of action in energy constrained environments.
