Used Waymo robotaxi batteries become backup storage for power grids

Waymo has announced a deal with energy storage company B2U to use retired robotaxi batteries to serve electricity grids in California and Texas. The used battery packs will be installed into grid-connected energy storage systems that can store electricity and send it back to the grid when demand is high. This partnership creates a sustainable pipeline for used electric vehicle batteries, fortifying local power grids with reliable energy storage and directly addressing electronic waste.
