At the RE+ 2025 conference in Las Vegas, Storion Energy LLC is preparing to make a case for why vanadium redox flow batteries (VRFBs) deserve a bigger place in the utility-scale energy storage mix. The company will be anchored in Stryten Energy’s Booth #F18033 from September 8–11 at The Venetian Expo and Caesars Forum, showcasing its high-quality vanadium electrolyte and stack power assemblies. But the real headline is not just the hardware—it’s the financing twist. Storion is promoting a vanadium electrolyte leasing model that converts one of the largest upfront costs of VRFBs into a manageable operating expense, which could dramatically accelerate adoption.
The concept tackles a known pain point: electrolyte often accounts for nearly half of a VRFB’s total cost. Unlike lithium-ion systems where the active material is built into the battery cells, flow batteries store their energy in large tanks of vanadium dissolved in liquid electrolyte. This material lasts decades and can be fully recycled, but the sticker shock of buying it upfront has limited project growth. By offering leasing terms, Storion is removing that barrier, making the technology more financially accessible for developers, utilities, and even independent power producers looking for long-duration energy storage (LDES).
Storion also brings vertical integration to the table. As a joint venture between an affiliate of Stryten Energy and Largo Clean Energy Corp., it draws on vanadium supply from one of the largest producing mines in the Western Hemisphere. Combined with domestic electrolyte production, the JV is positioning itself as a reliable and price-competitive supplier for U.S. projects. In a market rattled by fragile global supply chains and surging energy demand from AI data centers, EV infrastructure, and electrification efforts, this domestic resilience message carries weight.
The company will further spotlight its vision through a panel discussion, “Making Solar More Bankable,” held at the Stryten Energy booth on September 10 at 11 a.m. Storion CTO Travis Torrey will join voices from Infinite Energy Advisors, Dragonfly Energy, and Stryten Energy to debate how storage reshapes solar into a grid-ready, financeable solution. The panel promises to touch on reliability, regulatory shifts, integration challenges, and the future of solar-plus-storage, underlining how financing innovations like Storion’s can fit into broader strategies for lowering the levelized cost of energy while enhancing grid resilience.
For Storion, the RE+ 2025 platform is an opportunity to reposition vanadium flow batteries not as a niche alternative, but as a mainstream option for utilities needing storage that lasts hours, even days, without performance degradation. By turning the costliest component into a service rather than a purchase, the company is betting that finance can do what technology alone has not yet achieved: unlocking large-scale, bankable adoption of vanadium-based long-duration storage.
