Invinity Energy Systems has delivered 90 vanadium flow batteries to the Copwood VFB Energy Hub in East Sussex, forming Europe's largest such installation at 20.7 MWh, backed by UK government funding.

The US installed 9.7 GWh of new battery storage in Q1 2026—a 32% year-over-year jump and the highest first quarter ever recorded—as data center expansion and global gas disruptions outweigh federal permitting headwinds.

The 30 MW EFGL project off southern France began generating electricity on May 4, marking a milestone for floating offshore wind and anchoring a larger 250 MW follow-on.

The three-year agreement, equal to half of CATL's 2025 storage shipments, signals that sodium-ion has cleared its mass-production hurdles and is moving from pilot projects to grid-scale deployment.

Chinese battery makers are racing to add stationary-storage capacity while Beijing phases out export rebates, a shift that could tighten margins abroad and deepen domestic grid-storage demand.

A study published in Science shows lithium dendrites snap like glass rather than bending, challenging decades of assumptions that solid electrolytes alone could block them.

Minnesota PUC approves Xcel Energy's $430 million Capacity*Connect program to deploy up to 200 MW of utility-owned batteries, sparking a national debate over who should control distributed energy storage.

A KIST-IAE team engineered a tungsten diselenide catalyst that achieved over 550 stable cycles in lithium-air batteries, outperforming conventional catalysts and advancing a technology with ten times the energy density of lithium-ion.

Researchers at CSIRO, the University of Melbourne, and RMIT have built and tested a quantum battery prototype that completed a full charge-store-discharge cycle for the first time, demonstrating a counterintuitive property where charging speed increases with battery size.

Eve Energy, QuantumScape, Changan, and others are moving solid-state batteries from lab curiosity to production reality in 2026, but divergent strategies and persistent cost challenges will determine who leads the next era of energy storage.

The MIT spinout plans to demonstrate a 1 MWh thermal battery in Bedford, Massachusetts this year, using graphite bricks heated to 2,400 degrees Celsius and liquid tin to deliver grid-scale storage at a claimed $25 per kilowatt-hour, a fraction of lithium-ion costs.

Peak Energy and RWE Americas have deployed the first sodium-ion battery system on the MISO grid in Wisconsin, marking a milestone for the cheaper, cobalt-free chemistry in the US.
