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.
A team at the Institute of Metal Research engineered a new iron-complex electrolyte that ran 6,000 cycles at 80 mA per square centimeter with no capacity decay and a 99.4 percent average coulombic efficiency, opening a possible low-cost route to long-duration grid storage.
Meta signed a reservation deal for up to 100 GWh of ultra-long-duration storage from Noon Energy, a startup whose reversible fuel cell borrows chemistry from NASA's MOXIE Mars experiment.
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.
A 300 MW Form Energy iron-air battery paired with 1.6 GW of wind and solar will power Google's new Pine Island data center, marking the largest energy storage project ever announced by capacity.
