Invinity Energy Systems (LSE:IES) reported that the Pacific Northwest National Laboratory (PNNL), part of the U.S. Department of Energy, has started assessing the company’s vanadium flow battery at the newly opened Grid Storage Launchpad in Washington State. The testing program—initiated by U.S. Energy Secretary Chris Wright—represents a notable step forward for the DOE’s commitment to next-generation storage solutions. Over the coming year, Invinity’s system will undergo extensive performance trials to determine how effectively it can contribute to grid reliability, offering key data to advance large-scale storage technologies. The partnership with PPNL serves as an important endorsement of Invinity’s platform and strengthens its growing presence within the U.S. energy storage sector.
Although Invinity has recorded operational progress, its overall outlook remains constrained by steep financial losses and ongoing cash burn. Technical signals and valuation metrics also trend negatively. Still, recent strategic moves and corporate developments introduce some cautious optimism. The company’s longer-term prospects will depend heavily on execution and meaningful improvement in financial performance.
