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

Green Car Congress

The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. The quinones are dissolved in water, which prevents them from catching fire.

Classification of potential electrical storage for stationary applications. To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. This conversion produces a short, powerful burst of energy, such as needed to jump start a vehicle.
