Waymo partners with B2U to repurpose robotaxi batteries

Waymo · Jun 4, 2026 · https://techcrunch.com/feed/

Waymo, Alphabet's self-driving technology company, has announced a partnership with B2U Storage Solutions. This collaboration focuses on giving a second life to the batteries used in Waymo's robotaxi fleet. Instead of immediate recycling, these batteries will be repurposed for stationary energy storage applications.

This initiative matters because it addresses the growing challenge of battery waste from electric vehicles and autonomous fleets. By extending the lifespan of these high-capacity batteries, Waymo and B2U aim to reduce environmental impact and potentially lower the overall cost of battery ownership, contributing to a more sustainable circular economy for EV components.

The mechanism involves B2U taking Waymo's used electric vehicle batteries and integrating them into their energy storage systems. These systems can then be deployed for various uses, such as grid stabilization, renewable energy integration, or backup power. This repurposing extracts additional value from the batteries before they reach their end-of-life for recycling.

This partnership directly impacts Waymo (an Alphabet subsidiary, NASDAQ: GOOGL, GOOG) by potentially improving the economics of its robotaxi operations through battery cost savings and demonstrating its commitment to sustainability. It also benefits B2U Storage Solutions by providing a consistent supply of batteries for its core business of developing and deploying second-life battery energy storage systems.
