Waymo will repurpose retired electric vehicle batteries into grid storage to support electricity grids in the areas where it operates.

In partnership with B2U Storage Solutions, the project deploys EV battery storage systems that absorb surplus midday solar energy and discharge during late-afternoon demand peaks.

This second-life pathway extends battery usefulness for several more years before traditional recycling, providing stationary storage rather than disposal.

The initial rollout targets California and Texas, with planned operations in major Waymo-served cities such as Los Angeles, San Francisco, Houston, Dallas, Austin, and San Antonio.

This effort aligns with a broader surge in U.S. battery storage, as first-quarter 2026 set a record for storage capacity at 9.7 GWh, up 32% year over year.

The agreement envisions deploying hundreds of megawatts of storage capacity, though specific capacities or timelines were not disclosed.

Waymo’s fleet, including Jaguar I-Pace 90 kWh and Zeekr Ojai with 93 kWh batteries, has enough usable life remaining to support repurposing.

B2U already manages over 4,000 battery packs and notes a strong pipeline as demand for stationary storage grows.

B2U configurations include cabinets holding 24 to 54 packs with up to 2.5 MWh per cabinet, and the cells are used directly from vehicles without disassembly.

Waymo’s sustainability chief says the project will reduce reliance on dirtier energy sources at peak times and help decarbonize the grid.

The collaboration addresses end-of-life treatment for Waymo’s robotaxi fleet, which uses Jaguar I-Pace vehicles and increasingly Zeekr vans.

Waymo has historically prioritized renewable-energy charging, and the new deal reinforces a circular, clean-technology approach.
