About

Quino Energy is the leading developer of organic flow batteries, based on a water-based redox flow battery technology licensed from Harvard University, for utilities and communities. The batteries use chemicals made from coal tar and petroleum aromatics to store energy, rather than critical materials that use lithium, cobalt, nickel, vanadium, and so on. In addition, our batteries are nonflammable because all active materials are dissolved in water and the battery does not produce hydrogen during charging.

Quino Energy is piloting organic flow batteries at MW-scale for industrial microgrid and renewable energy storage applications. At the company’s R&D Headquarters in San Leandro, California, the team is building, refining, and testing battery prototypes, working with vendors and partners to scale up system size, and continuing to push the limits of flow battery technology. From our Houston, Texas Business Office, the Sales and Business Development team engages global partners and customers, to support product development, piloting, and planning for commercial deployments.
