Storion Energy, a joint venture between Stryten Energy LLC and Largo Clean Energy Corp. (LCE), was announced on February 4, 2025, with the objective of establishing a domestic supply chain for vanadium redox flow battery (VRFB) components. The partnership aims to provide competitively priced vanadium electrolyte through a unique leasing model, facilitating the rapid commercialization and adoption of VRFB technology for long-duration energy storage (LDES) applications.
Storion Energy intends to lower entry barriers for battery manufacturers by offering domestically sourced, high-quality flow battery components, including vanadium electrolyte. The joint venture leverages access to vanadium from the only operational Western Hemisphere vanadium mine, combined with domestic production capabilities to create a fully integrated supply chain for utility-scale VRFBs. This approach supports the Department of Energy’s goal to deliver reliable energy at $0.05 per kilowatt-hour by 2030.
Using proprietary continuous manufacturing and patented purification processes, Storion Energy plans to supply high-purity electrolyte essential for VRFB performance. The leasing model, exclusive to Largo Physical Vanadium Corp., allows Storion to offer vanadium electrolyte economically, addressing the significant portion of VRFB system costs associated with vanadium. This model is designed to make VRFBs more competitive against the upfront capital costs of lithium-ion battery energy storage systems (BESS).
Mike Judd, CEO and President of Stryten Energy, highlighted the venture’s potential to enable the widespread adoption of VRFB technology for utility-scale BESS applications, emphasizing the safety and reliability of VRFBs in providing energy resilience for critical commercial and industrial operations.
Francesco D’Alessio, President of LCE, noted that the joint venture advances their vanadium electrolyte leasing offering in the North American market. He indicated that Storion Energy’s pricing model is expected to challenge lithium-ion dominance in utility-scale deployments, thereby promoting increased adoption of VRFB technology and establishing U.S. leadership in this key energy infrastructure sector.
VRFB technology is recognized for its ability to provide long-duration energy storage exceeding four hours, ensuring grid stability and enhancing the integration of renewable energy sources. VRFBs offer a lifespan of over 20 years without significant electrolyte degradation, complementing the longevity of wind and solar installations. Additionally, the electrolyte is fully recyclable, and the battery system boasts nearly limitless cycle life. The scalability of VRFBs in both power and capacity further contributes to potential cost reductions, particularly as discharge times increase, positioning VRFBs as a preferred solution for sustainable, large-scale energy storage.
