Department of Energy Office of Electricity (DOE OE) has published a series of reports supporting their Long Duration Storage Shot, which aims to develop specific and quantifiable RD&D pathways to reduce the cost of grid-scale energy storage by 90% for systems that deliver 10+ hours of duration by 2030. DOE recently published eleven technical reports summarizing and analyzing explore the promising RD&D pathways to substantially lower the costs of long-duration energy storage.
