Quino Energy is scaling up an aqueous flow battery that uses specially designed reactants called quinones that are dissolved in water. They are made from low-cost coal tar and wood tar, and are more cost-effective than competing battery technologies at longer storage durations of 5-12 hours. Quino Energy has licensed the quinone flow battery technology from Harvard University, where it was first developed. Quino’s storage solutions are ideal for grid resiliency applications such as microgrids, transmission and distribution deferrals, and renewables storage at scales ranging from homes to large solar farms. Our batteries have ultralow capacity degradation without generating hydrogen gas or requiring frequent rebalancing. They can be sited anywhere, even where fire or wildfire risk precludes deployment of “conventional” lithium-ion batteries.
