DOE Putting Funds Toward Long-Duration Energy Storage Projects


The U.S. Department of Energy (DOE) has announced up to $325 million for 15 projects across 17 states and one tribal nation to accelerate the development of long-duration energy storage (LDES) technologies.

These demonstration projects will increase community control of local power systems, mitigate risks associated with disruptions to the grid, and help communities develop reliable and affordable energy systems.

The announcement will help DOE realize its Long Duration Storage Shot goal of reducing the cost of LDES by 90% by 2030 and supports the Biden-Harris administration’s efforts to advance critical clean energy technologies, expand the adoption of renewable energy resources, and strengthen America’s energy security.  

“As we build our clean energy future, reliable energy storage systems will play a key role in protecting communities by providing dependable sources of electricity when and where it’s needed most, particularly in the aftermath of extreme weather events or natural disasters,” says U.S Secretary of Energy Jennifer M. Granholm. “DOE is supporting game-changing energy storage projects across the nation – laying the foundation for the innovative solutions we need to ensure stronger, more resilient communities.”

The LDES Demonstrations Program, managed by DOE’s Office of Clean Energy Demonstrations (OCED), funds a range of different technology types intended to overcome technical and institutional barriers to full-scale deployment of LDES systems in diverse geographies and climates. Projects selected will feature a range of intraday (10 to 36 hours) and multiday (36 to 160+ hours) storage solutions, which can minimize the frequency and length of power interruptions caused by events such as severe weather or cyberattacks on the grid.
