Since TFA didn't really explain what a "flow" battery is: https://en.wikipedia.org/wiki/Vanadium_redox_battery https://en.wikipedia.org/wiki/Vanadium_redox_batt

  > In the ESO hybrid energy storage system, Invinity’s vanadium flow batteries are used to ‘front-end’ the energy asset, acting as a first line of response when the system is called into service; only after the required response exceeds the capacity of the Invinity battery does the lithium-ion battery get called into service. Since Invinity’s flow battery does not degrade with use and can cycle indefinitely, it performs much of the ‘heavy-lifting’ required from the system while reducing wear on the lithium-ion battery. From TFA.
