Waymo’s old robotaxi batteries are getting a second life on the grid
Waymo’s spent robotaxi batteries are being repurposed for grid storage, showing how autonomous and electric fleets could feed a circular battery economy.
What happened
Waymo’s old robotaxi batteries are being repurposed for grid storage.
Instead of treating end-of-vehicle-life batteries as waste, the batteries can still be useful in stationary energy applications.
Why it matters
As electric and autonomous fleets grow, they will create a new wave of battery assets.
Those batteries may no longer be ideal for vehicles, but they can still help store energy, support the grid, and extend the value of expensive hardware.
The bigger picture
Mobility and climate tech are increasingly connected. EV fleets are not just transport systems — they may become part of the energy infrastructure lifecycle.
My take
This is the kind of unsexy infrastructure story that actually matters. The robotaxi future is not only about cars driving themselves. It is also about what happens to all the batteries afterwards.
