(Alliance News) - Invinity Energy Systems PLC on Friday announced a partnership with a strategic partner, aiming at providing energy storage at large scale in China.
The London-based manufacturer of utility-grade energy storage systems said it is collaborating with Guangxi United Energy Storage New Materials Technology Ltd, a manufacturer of vanadium electrolyte and battery products based in the Guangxi Zhuang Autonomous Region in China, in the south of the country.
Invinity said the companies have found an opportunity for vanadium flow batteries to provide effective, reliable and high-performance energy storage at large scale in China that is commercially viable.
Invinity added that it has agreed to support Guangxi United's "efforts to establish manufacturing capacity, reduce production costs and actively market and sell Endurium within China, working together to deliver excellence in production and sales and mutually explore opportunities to implement continuous improvements, efficiencies and value to manufacturing."
Endurium is Invinity's fourth-generation vanadium flow battery which aims to optimise the firm's product platform for large-size energy storage up to gigawatt scale.
Guangxi United Executive Director Liao Zhanghui said: "We are delighted to formally recognise this strategic partnership between Invinity and [Guangxi United]. Supported by the Xiamen government, we look forward to a strong and successful cooperation between our companies which will advance the deployment of vanadium flow batteries globally and further accelerate Endurium product development."
In June, Invinity announced that Endurium was selected for several UK long-duration energy storage cap & floor bid applications.
"The company is highly encouraged to have received a significant level of interest from UK battery developers planning to use Endurium batteries in their project bids," Invinity said at the time.
It added that the bids are under review by Ofgem to confirm eligibility before they progress to the final assessment phase which it expects to conclude in the first half of 2026.
Invinity Chief Executive Officer Jonathan Marren said in June: "Should these bids be successful, we believe the build out of our Endurium batteries across the country will not only help to lower energy costs for consumers but also help to provide wider economic benefits across the UK as we scale our operations."
Invinity Energy shares were up 11% to 26.19 pence midday Friday in London for a market capitalisation of GBP111.4 million.
