Long Duration Energy Storage

Long duration energy storage (LDES) technologies are rapidly advancing as a solution to enable deep grid penetration of renewable energy sources with high variability such as solar and wind power. LDES technologies are being developed as a cost-effective alternative to grid-scale electrochemical batteries for extended periods from a few hours to days, weeks, or months of storage. The U.S. Department of Energy, grid operators and utilities are helping to commercialize compressed air, pumped heat, advanced pumped hydro, flywheels, thermal, gravitational and hydrogen or other chemistry-based storage systems. Southwest Research Institute supports the non-battery storage industry with research and development and technical solutions, including:
