Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

In contrast, flow batteries can independently scale the power (electrode area) and energy (arbitrarily large storage volume) components of the system by maintaining all of the electro-active species in fluid form. —Huskinson et al. Background. The active components of electrolytes in most flow batteries have been metals.

Mad Power thoughts

EV Info

Yet whenever we troublemakers raised this issue, we were told not to worry – it would resolve itself, they said, either because wind is usually blowing somewhere, or through the development of electricity storage in giant battery farms. The cost of grid management has soared to nearly £2billion a year in the last two decades.
