Defining long duration energy storage

Energy storage is a dispatchable source of electricity, which in broad terms this means it can be turned on and off as demand necessitates. But energy storage technologies are also energy limited, which means that unlike a generation resource that can continue producing as long as it is connected to its fuel source, a storage device can only operate on its stored
