Long-Duration Energy Storage
Funds long-duration energy storage pilots and demonstrations that prove technical and commercial viability.
Long-Duration Energy Storage is an Office of Clean Energy Demonstrations program for storage technologies that can support a more reliable clean-energy grid. The official page lists two closed OCED funding rounds: a $349 million Demonstrations Program FOA issued in November 2022 and a $100 million Pilot Program NOFO issued in September 2024. This catalog entry folds those rounds into one durable LDES record because they share the same OCED program page and technology scope. The page says the program is meant to demonstrate the technical and commercial viability of long-duration energy storage technologies, which creates a direct path for companies developing storage hardware, controls, integration, or project platforms. The record is closed because both listed rounds are past funding announcements; applicants should use it to track the program history and watch DOE for successor LDES notices.
