Waymo Sends Retired Robotaxi Batteries to Grid Storage Projects

*Waymo will route spent battery packs from its autonomous vehicles to stationary energy storage through a new agreement with B2U Storage Solutions.*

Waymo has struck a deal to send retired battery packs from its robotaxi fleet to grid-scale storage installations. The packs will support energy projects in California and Texas after they are removed from service.

The arrangement hands the used modules to B2U Storage Solutions, which specializes in second-life battery deployments. Waymo gains an outlet for packs that no longer meet vehicle standards, while B2U gains inventory for stationary systems without purchasing new cells.

Both companies described the move as a direct transfer of packs already pulled from vehicles. No new technical modifications or performance data were released.

Limited Scope So Far

The announcements mention only California and Texas projects. No volume figures, contract length, or financial terms appear in either statement. It remains unclear how many packs will move each quarter or what share of Waymo’s fleet this covers.

Why it matters

The arrangement extends the economic life of high-value battery hardware that would otherwise exit the supply chain early. For grid operators it offers a lower-cost storage option; for Waymo it reduces disposal overhead. Whether the program scales depends on how many packs actually qualify and how quickly B2U can integrate them into operating sites.

The next measurable signal will be the first megawatt-hours placed online from these packs.
