Used Waymo robotaxi batteries become backup storage for power grids

Thousands of electric vehicles in Waymo's autonomous robotaxi fleet may soon find a new life after their batteries have been depleted for driving. The company has entered into a strategic supply agreement with B2U Storage Solutions, a firm that specializes in repurposing used EV batteries for stationary energy storage projects. This partnership could lead to the deployment of hundreds of megawatt-hours of energy storage capacity, supporting local power grids during peak demand periods.

The collaboration brings together Waymo's vast fleet of electric robotaxis and B2U's innovative approach to giving used batteries a second chance. By installing these batteries in large stationary energy storage facilities, excess renewable energy can be captured during times of low demand and released when the grid needs it most. This not only reduces strain on the grid but also helps to promote a more efficient use of renewable energy sources.

For B2U, this partnership represents a significant opportunity to expand its operations and further develop its technology. According to Freeman Hall, CEO of B2U Storage Solutions, the company's business model focuses on extracting the full residual value from electric vehicle batteries once they're no longer suitable for automotive use. With Waymo's rapid expansion plans and high-mileage EV fleet, B2U is eager to work with the company and explore the potential of repurposed batteries.

"Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use," Hall told Ars. "Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them." The partnership between Waymo and B2U Storage Solutions highlights the growing importance of sustainable energy solutions and the creative ways in which companies are working to reduce waste and promote efficiency. As the demand for electric vehicles and renewable energy continues to grow, innovative approaches like this one will play a crucial role in shaping a more sustainable future.

By breathing new life into used EV batteries, Waymo and B2U are not only reducing waste but also contributing to a more resilient and efficient energy infrastructure. As this technology continues to evolve, it will be exciting to see how other companies follow suit and explore new ways to repurpose and reuse materials.
