In a major stride towards global expansion, Invinity Energy Systems has signed a licensing and royalty agreement with Guangxi United Energy Storage New Materials Technology Limited (UESNT), marking the company’s formal entry into the Chinese energy storage market.
UESNT, based in China’s Guangxi Zhuang Autonomous Region, specializes in vanadium electrolyte and battery manufacturing. This partnership aligns with China’s massive demand for scalable, high-performance energy storage and leverages both parties’ strengths: Invinity’s proven vanadium flow battery (VFB) technology and UESNT’s access to vanadium resources and local manufacturing capability.
The agreement grants UESNT rights to manufacture, sell, and market Invinity’s ENDURIUM VFB systems in China until 2030. In return, UESNT will pay royalties based on volume, including two milestone-linked payments. The target is to produce at least 1.9 GWh of ENDURIUM batteries, with an initial 300 MWh scheduled for 2026, subject to final confirmation.
Importantly, the collaboration allows Invinity to source components and full systems from UESNT for projects outside China, helping reduce global manufacturing costs. Furthermore, Invinity gains access to a long-term, fixed-price vanadium electrolyte supply through UESNT — sufficient for up to 6 GWh of VFB capacity — helping advance its cost reduction roadmap.
The agreement was signed in London by Invinity CEO Jonathan Marren and UESNT Executive Director Mr. Liao Zhanghui, in the presence of dignitaries including Xiamen Mayor Wu Bin and UK Government’s Office for Investment Director John Edwards.
Marren highlighted the strategic nature of the alliance, calling it “an exciting opportunity to address Chinese market demand and enhance global competitiveness through cost-efficient manufacturing.” Mr. Zhanghui echoed this, emphasizing shared ambitions to expand ENDURIUM deployment and lower storage costs worldwide.
