Long-Duration Energy Storage intelligence — updated daily.
EU sanctions against the largest vanadium producer outside China coincided with a US benchmark ferrovanadium price roughly 24% above European levels, a spread that feeds directly into flow battery electrolyte economics.
Only one project on the European Commission's Innovation Fund projects list is categorised under energy storage — Talos, a Greek intra-day electricity storage project selected under the IF25 Call and invited to grant agreement preparation.
Largo Inc.'s Storion Energy signed a strategic supply agreement with TerraFlow Energy covering vanadium electrolyte and battery stacks, and secured an electrolyte lease for a 48 MWh flow battery project in Texas.
Vanadium flow batteries store energy in external liquid electrolyte reservoirs, a design that allows duration to be extended by increasing electrolyte volume rather than rebuilding the cell stack.
AIM-listed Invinity Energy Systems is seeking at least £20 million through a subscription, institutional placing and retail offer at 10p per share, with proceeds earmarked for development, working capital and manufacturing capacity.
The Pacific Northwest National Laboratory has introduced a closed-loop workflow combining digital and physical frameworks for high-throughput experimentation. This autonomous synthesis approach aims to rapidly discover and optimize new redox-active molecules for flow batteries.
The Central Electricity Authority of India projects a total storage capacity of 73.93 GW by 2031-32, driven by pumped storage and battery systems. This infrastructure is critical for achieving the nation's ambitious 500 GW non-fossil fuel target by 2030.
Xcel Energy has unveiled a massive 300 MW, 30 GWh iron-air battery project in Minnesota to supply clean power to a new Google data center. Utilizing Form Energy's technology, it marks the largest energy storage project by capacity ever announced globally.
Researchers at the Chinese Academy of Sciences have developed an alkaline all-iron flow battery that sustains over 6,000 cycles without capacity decay. This breakthrough offers a highly cost-effective and safe alternative to lithium-ion for grid-scale storage.
Invinity Energy Systems plans to raise at least £20 million to accelerate product development, cost reduction, and manufacturing capacity. The fundraise is backed by its major shareholder, the National Wealth Fund, alongside a leadership transition.
While vanadium redox flow batteries face severe corrosion challenges, companies like Prudent Energy are advancing modular systems and proprietary materials to overcome these technical barriers for grid-scale deployment.
A FactSet model reveals significant energy arbitrage potential for 100-hour iron-air batteries in MISO and PJM markets, with profitability doubling in 2026 due to seasonal pricing dynamics.
