Long Duration Energy Storage (LDES) refers to technologies that store energy for extended periods, typically beyond 4-6 hours, for later use. These systems help balance renewable energy supply, enhance grid stability, and ensure energy resilience by storing surplus power during low-demand periods and discharging it when demand is high.

The main LDES technologies include pumped hydro storage (PHS), compressed air energy storage (CAES), liquid air energy storage (LAES), flow batteries, and solid-state batteries. Pumped hydro storage works by pumping water to a higher elevation during low electricity demand and releasing it through turbines to generate power during peak demand. Storage capacities are categorized as up to 50 MW, 50-100 MW, and more than 100 MW, with duration classifications of up to 8 hours, 8-10 hours, and above 10 hours. Key applications include grid energy storage, off-grid energy storage, and backup power, serving sectors such as utilities, industrial, commercial, and residential markets.North America was the largest region in the long duration energy storage market in 2025.
