Google has committed $1 billion to Form Energy for a 30 gigawatt-hour iron-air battery system, the largest single energy storage order ever reported. Form's technology uses iron and air instead of lithium, storing electricity for up to 100 hours at a fraction of the cost of lithium-ion. This is not a pilot. This is grid-scale procurement from one of the world's largest data center operators.
The deal matters because it validates long-duration storage as a real market, not a research category. Google needs firm, dispatchable power to run AI infrastructure around the clock. Wind and solar alone cannot deliver that. A 30 GWh order is roughly 10 times the capacity of Tesla's Hornsdale Power Reserve in Australia, the project that put grid-scale batteries on the map in 2017.
