  3. Slide 3: Synopsis

    Synopsis • LONG DURATION ENERGY STORAGE (LDES) does not mean 2-hours storage and dispatch. It does not mean 4- hours. It means at least 10-hours storage and dispatch, and it also means you should be able to do that every day of the year. For personal use only • OPERATING TEMPERATURE RANGE: The singl
