27x 20ft shipping containers combine to form a 5mw vanadium flow battery buffering a 50mw lithium battery. Which is interesting but the fact it's not 100% flow

27x 20ft shipping containers combine to form a 5mw vanadium flow battery buffering a 50mw lithium battery. Which is interesting but the fact it's not 100% flow battery suggest lithium must still be sufficiently cheaper to overcome its shorter life.
- ok_dad 5y ago> 27x 20ft shipping containers combine to form a 5mw [it's 5MWh, not 5MW] vanadium flow battery This seems like a LOT of space required for such a low capacity. For a 5MWh flow battery, I wonder what the peak power output actually is from the system? for LiIon, you would see about ~1MW peak power from such a small reserve of energy. Flow batteries are longer lasting, so I assume this battery is less peak output. I am pretty sure that the LiIon battery will be doing the heavy lifting here, sized as it is. This isn't a huge leap forward.
