The U.S. Department of Energy (DOE) recently announced up to $325 million for 15 projects 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. These projects will help DOE realize its Long Duration Storage Shot goal of reducing the cost of LDES by 90% by 2030 and will advance critical clean energy technologies, expand the adoption of renewable energy resources, and strengthen energy security.
