Used Waymo robotaxi batteries become backup storage for power grids
Summary
Ars Technica reports that Waymo's used robotaxi batteries are being repurposed into stationary energy storage via a strategic agreement with B2U Storage Solutions, enabling up to hundreds of MWh of capacity for grids in California and Texas. The initiative highlights battery lifecycle management and circular economy opportunities, showing how repurposed EV cells can support renewable energy and grid reliability. It also notes ongoing degradation and the potential scale as Waymo's fleet grows.
