A promising technology for performing that task is the flow battery, an electrochemical device that can store hundreds of megawatt-hours of energy — enough to keep thousands of homes running for many hours on a single charge. Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design.
Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage systems. These batteries have, and will likely continue to have, relatively high costs per kWh of electricity stored, making them unsuitable for long-duration storage that may be needed to support reliable decarbonized grids.
