Waymo announced a deal with an energy storage company called B2U to use retired robotaxi batteries to serve electricity grids in California and Texas.

The deal helps answer the question of how Waymo is thinking about the end-of-life treatment of the thousands of robotaxis it has deployed around the United States. Almost all of those are currently Jaguar I-Pace EVs, though the company has recently started deploying a limited number of vans built by Chinese automaker Zeekr.
