Hadn't heard of these--'flow batteries.' A-H capacity is set by storage
volume of aqueous electrolytes, hence easily scaled.
Dept. of Energy(Restriction)-financed, so they must be good ;-)

Filling stations could change out your electrolyte, quickly charging
a car.
I wonder what would be the energy density compared to gasoline. I'd
suspect it to be really bad. Gasoline is burned 100% and the oxidizer
component weighs nothing. And you can dump the waste products
overboard.
I was thinking of it compared to LiIon. This flow battery has 167 watt-hours/
liter versus 233 for LiIon, but the flow batt replaces lots of metal with water.
Could be lighter. Maybe.
