Quino Energy

Quino Energy is a clean energy storage company that develops water-based flow batteries using organic quinone molecules for commercial and grid-scale energy storage applications. The company was formed to commercialize aqueous organic flow battery technology pioneered at Harvard University, storing electrical energy in specially designed quinones dissolved in water. Quino Energy's proprietary process converts dyestuff raw materials directly into high-performance designer quinones using the flow battery system itself as the production reactor, enabling new chemistry without requiring a new factory while creating zero chemical waste. This approach dramatically reduces manufacturing costs and capital expenditure compared to traditional battery production. The company's aqueous organic flow battery technology offers practical, affordable grid storage with the safety advantages of water-based chemistry, eliminating the fire risks associated with lithium-ion systems. Quino Energy's quinone-based flow batteries are designed for long-duration energy storage suitable for commercial and grid applications, supporting renewable energy integration, microgrid deployment, and grid resilience. The company has received recognition including an award from Tencent's CarbonX Program for a MWh-scale island microgrid project in the Maldives, demonstrating the technology's applicability for remote and island microgrid installations. The technology also includes capabilities for bringing degraded quinones back to life, extending system longevity and reducing lifecycle costs. Founded in 2021 and headquartered in Menlo Park, California, Quino Energy has raised $14.7M in Series A funding from investors including ANRI, TechEnergy Ventures, Doral Energy Group, ERV, Energy Revolution Ventures, DOE, Atri Energy Transition, and OSTI.
