Ever wonder what keeps your lights on when the sun isn’t shining or the wind isn’t blowing? Big power companies are now testing iron-sodium batteries—think giant, safer, and cheaper versions of what’s in your remote.

Watch this space: your wallet (and the planet) could thank you soon! #Business #Industry #EnergyStorage
