Waymo Repurposes Electric Robotaxi Batteries for Energy Storage Solutions

• June 4, 2026

Waymo, the autonomous vehicle unit under Alphabet Inc., has launched a new initiative aimed at extending the lifecycle of electric vehicle batteries. Rather than disposing of used batteries from its fleet of electric robotaxis, the company will repurpose them into stationary energy storage systems for power grids.

Transforming Transport Batteries into Energy Assets

With the growing demand for sustainable energy solutions, repurposing electric vehicle batteries presents an opportunity to reduce waste and maximize resource usage. Waymo’s plan involves taking depleted batteries that have served their purpose in autonomous taxis and converting them into energy storage units designed to support electrical grids.

This approach helps mitigate the environmental impact associated with battery disposal and recycling by offering a secondary application that extends the battery’s functional life. Stationary energy storage plays a critical role in energy management, enabling better integration of renewable sources and improving grid reliability.

To realize this project, Waymo has partnered with B2U Storage Solutions, a company specializing in energy storage systems crafted from used electric vehicle batteries. B2U’s expertise in converting second-life batteries into efficient, reliable storage units complements Waymo’s sustainability goals.

While details about implementation timelines and system capacities have not been disclosed, the program underscores an emerging industry trend that focuses on the circular economy in electric vehicle technology. Instead of prematurely discarding electric car batteries, reusing them in alternative applications supports the broader sustainability and energy efficiency agenda.

This initiative aligns with Alphabet’s wider commitments to green technology and reducing carbon footprints. As autonomous electric taxis generate substantial battery assets, repurposing these components highlights the potential for future collaborations between vehicle manufacturers, energy companies, and sustainability organizations.

Overall, by turning decommissioned robotaxi batteries into grid support tools, Waymo is contributing to innovative energy solutions that could influence how electric vehicle battery lifecycle management evolves in the coming years.
