NREL’s Storage Futures Study (SFS) explores how energy storage technology advancement could impact utility-scale storage deployment and distributed storage adoption, as well as future power system infrastructure investment and operations.
The first paper in this series, The Four Phases of Storage Deployment: A Framework for the Expanding Role of Storage in the U.S. Power System outlines a conceptual framework for the possible evolution of the stationary energy storage industry—and the power system as a whole.
The four phases, which progress from shorter to longer duration, link the key metric of storage duration to possible future deployment opportunities, considering how the cost and value vary as a function of duration, with the potential to reach more than 100+ GW of installed storage capacity in the U.S.
