About
Quino Energy develops aqueous organic flow batteries for grid-scale energy storage at durations of 5–24 hours. Its water-based chemistry uses quinone molecules derived from low-cost coal tar and wood tar, making energy storage more cost-effective than lithium-ion at longer durations. Quino licensed its foundational technology from Harvard University and uses the flow battery system itself as the production reactor, enabling zero-waste manufacturing without new factory infrastructure. Applications include microgrids, transmission deferral, and utility-scale renewables storage.
