Invinity Energy Systems Plc has launched ENDURIUM, a fourth-generation modular vanadium flow battery (VFB) designed for large-scale energy storage, with a capacity of up to 1 gigawatt-hour. According to VSA Capital, the product offers significant advantages over lithium-ion batteries, including greater energy density and lower costs. The company is financially positioned for growth, with £49 million in cash. VSA projects a 619% return potential, estimating shares could rise from £14.6 to £105. Invinity has secured orders and plans to market ENDURIUM in the U.K., North America, and globally through partnerships.
