FORM Energy just announced their chemistry behind multi-day long duration energy storage systems.

Their chemistry involves iron pellets and rust. The cost is $20 per kWh compared to the $100/250 per KWh.

According to Russel Gold reporting for the Wall Street Journal, the FORM Energy's iron-air battery breathes in oxygen and charges by creating rust when oxygen converts iron to rust. Then, the battery breathes out oxygen and discharges.

Great River Energy, an electric MISO transmission owner coop member contracted with FORM Energy for 150 hour storage.

This is exciting news for the energy storage industry, especially for cold climates where there is a worry if the battery lasts longer than 2/4/6 hours storage.

Whoa that would be huge! I don't see mention in the article about timeline-- when might this be grid-ready?
