Quino Energy, a U.S.-based developer of water-based organic flow batteries, has announced the closure of a $10 million Series A funding round led by Atri Energy Transition, with an additional $6 million equity option, taking the potential total investment to $16 million. The funding will accelerate the company’s plans to establish a dedicated manufacturing line, initiate pilot demonstrations, and form strategic partnerships across global energy markets.
Quino Energy aims to commercialize its proprietary organic flow battery electrolyte, which can be integrated into existing vanadium flow battery hardware with minimal modification. This compatibility, the company says, will enable rapid scale-up and cost-effective deployment for mid- to long-duration energy storage applications.
“The close of our Series A funding represents a key milestone toward making our safe, low-cost flow batteries the leading option for multi-cycle and long-duration storage,” said Eugene Beh, Co-Founder and CEO of Quino Energy. He added that the company’s next-generation electrolyte factory is expected to achieve production costs significantly below that of vanadium, promising up to 75% cost reductions at GWh-scale manufacturing.
Quino Energy’s technology leverages an innovative, zero-waste, continuous-flow production method using inexpensive feedstocks derived from coal tar. The mildly alkaline, chloride-free electrolyte is also compatible with carbon steel tanks, enabling the repurposing of oil storage infrastructure for large-scale battery installations—an advantage that could reshape storage economics.
Atri Energy Transition Founder S. Kishore emphasized the global need for economical and scalable long-duration energy storage (LDES) solutions.
“Quino Energy’s organic electrolyte has the potential to revolutionize the energy storage sector. We’re excited to support a technology that can bring commercially viable LDES to markets worldwide,” he said.
The Series A announcement builds on a strong year for Quino Energy. Earlier in 2025, the company received a $10 million grant from the California Energy Commission and $5 million from the U.S. Department of Energy’s CiFER program to support a 5 MWh flow battery installation in Southern California. It also secured a strategic collaboration with TerraFlow Energy to advance organic electrolyte solutions for large-format flow batteries.
