Large-scale battery storage systems are increasingly being used across the power grid in the United States. Over 90% of large-scale battery storage power capacity in the United States was provided by batteries based on lithium-ion chemistries. Beyond battery (Lithium-ion), we also need to advance other long-duration storage technologies to decrease the need for building peak power plants. The innovative work in this area would be to develop technoeconomic targets for lifetime, efficiency, and cost for various storage durations; explore novel non-Li-ion energy storage technologies and their grid applications. Storage is not a generation source but a way of buffering diurnal & seasonal fluctuations. But costs are high and interface with generation may be difficult.
