Waymo Gives Old EV Batteries a New Job

Waymo is giving its used robotaxi batteries a second life as stationary storage for California and Texas power grids.

Waymo has announced a strategic partnership with B2U Storage Solutions to repurpose batteries from its electric robotaxi fleet. Under the agreement, batteries that are no longer suitable for powering vehicles will be given a second life. Instead of being discarded, they will be used to create stationary energy storage systems. These systems will support power grids in California and Texas, two key regions for both Waymo's operations and energy innovation. The deal provides a sustainable end-of-life solution for a critical component of Waymo's autonomous vehicles. B2U will integrate these used batteries into its projects, helping to store renewable energy and improve grid stability. This collaboration directly addresses the growing challenge of managing used electric vehicle batteries as the industry scales up.

This move is significant for founders and CTOs in the automotive, energy, and sustainability sectors. It demonstrates a practical application of the circular economy, turning a potential liability into a valuable asset. For companies operating large EV fleets, this strategy offers a blueprint for responsible asset lifecycle management. It proves that hardware from one high-tech application can be effectively repurposed for another, creating new revenue streams and reducing environmental impact. The partnership also highlights an emerging synergy between the transportation and energy industries, where EV infrastructure can directly support the power grid. This approach could become a competitive advantage for companies that adopt similar models, showcasing a commitment to both innovation and sustainability.

Looking ahead, this initiative could set a precedent for the entire autonomous and electric vehicle industry. As fleets of EVs expand globally, the volume of retired batteries will surge, making second-life applications essential for long-term viability. By providing a steady supply of used batteries, Waymo helps B2U scale its energy storage solutions, potentially lowering costs and accelerating the adoption of renewable energy. This model of collaboration between a tech-forward fleet operator and an energy storage specialist could be replicated in other regions. It represents a crucial step toward building a more integrated and resilient infrastructure where transportation and energy systems work together to solve complex challenges.

This initiative provides a blueprint for the circular economy, showing how EV fleet operators can sustainably manage hardware lifecycles and create value from used assets while supporting energy infrastructure.

This partnership creates a new revenue stream for Waymo from depreciated assets and provides B2U with a consistent supply of batteries for its energy storage projects, potentially lowering costs and improving grid stability.
