As America moves closer to a clean energy future, energy from intermittent sources like wind and solar must be stored for use when the wind isn’t blowing and the sun isn’t shining. The Energy Department is working to develop new storage technologies to tackle this challenge -- from supporting research on battery storage at the National Labs, to making investments that take startup concepts to grid-scale solutions.
