Quino Energy develops water-based flow batteries for grid-scale energy storage applications. Founded in 2021 and based in California, the company specializes in utilizing organic molecules called quinones to store electrical energy. Their technology originated from research at Harvard University and offers an alternative to traditional lithium-ion batteries for mid-duration energy storage needs. The company’s innovative approach converts raw dyestuff materials directly into high-performance quinones using the flow battery system as a production reactor, eliminating the need for additional manufacturing facilities while maintaining zero chemical waste production.
Battery Technology
Quino Energy’s core technology centers on water-based flow batteries that store energy through quinone molecules dissolved in water. These organic compounds can switch between oxidized and reduced states, making them ideal for energy storage applications. The system provides true fire safety advantages by eliminating the need for critical minerals or dangerous synthetic chemicals.
The manufacturing process stands out for its efficiency and environmental considerations. The company’s pilot production line has achieved manufacturing readiness level (MRL) 7, enabling production of up to 100 kWh of organic battery material reactants daily. The technology allows for simple scaling of energy storage capacity through increased electrolyte tank size, offering cost advantages for longer duration storage compared to lithium-ion alternatives.
Their batteries are designed for 8-24 hour energy storage periods, specifically targeting commercial and utility applications. The system’s compatibility with existing vanadium flow battery hardware enables quick integration into current infrastructure with minimal modifications. Additionally, the use of abundant coal tar chemicals as raw materials ensures a reliable domestic supply chain in the United States.
Recent Projects
In early 2024, Quino Energy secured a $2.6 million grant from the U.S. Department of Energy’s Advanced Materials and Manufacturing Technologies Office. This funding supports the development of two significant pilot systems: a lab-scale 3 kW/24 kWh system and a commercial-scale 200 kW/2 MWh system. The larger system is scheduled for completion by late 2026, with performance evaluations planned for at least 18 months.
Investors
Quino Energy has raised $4.55 million in seed funding from several investors, including Energy Revolution Ventures, Doral Energy Tech Ventures, and TechEnergy Ventures. The U.S. Department of Energy provided additional support through a $4.58 million grant. The company’s board includes representation from ANRI, a Japanese venture capital firm, through Masahiro Sameshima.
