Invinity Energy Systems has unveiled an upgrade to its Endurium battery platform that it says makes the technology meaningfully more competitive and cheaper to deploy.
The AIM-listed company, which builds vanadium flow batteries, said the latest Endurium module now on general sale delivers 50% more energy capacity and 33% more peak power.
The gains come from a mix of changes including more electrolyte, upgraded power-distribution hardware and improved control software.
Because each module now does more, Invinity said fewer are needed for a given project, cutting the equipment, space, installation and lifecycle costs that have long weighed on flow batteries against cheaper lithium-ion rivals.
Jonathan Marren, Chief Executive Officer at Invinity, said: “This latest performance upgrade to Endurium marks another milestone in the continued development of our product.”
The company framed the step as evidence it is delivering on the cost-reduction programme it has repeatedly promised shareholders.
No order or revenue figure was attached, so the commercial payoff rests on whether the improved economics translate into firm sales.
Shares were little changed on the news, and the stock remains down heavily on the year after recently conducting a placing.
