Waymo has announced a programme to repurpose retired electric vehicle batteries from its robotaxi fleet for use in grid-scale energy storage, in collaboration with B2U Storage Solutions.
The initiative is designed to extend the usable life of batteries after their use in autonomous vehicle operations by deploying them in stationary energy systems connected to local electricity networks.
The programme will redirect batteries from Waymo’s autonomous ride-hailing fleet into energy storage facilities once they are no longer suitable for vehicle use. Instead of being sent directly for recycling, the batteries will be used in systems that store surplus electricity and release it when demand on the grid increases.
B2U Storage Solutions will oversee the technical integration and operation of the storage systems. The company specialises in repurposing electric vehicle batteries for stationary use, where performance requirements differ from those in automotive applications, allowing continued operation after vehicle retirement.
The initiative is part of Waymo’s wider fleet and sustainability approach, which includes extending component lifespan through maintenance and operational efficiency. Reusing batteries supports more efficient use of materials and helps expand energy storage capacity in regions with growing renewable electricity generation.
Adam Lenz, Head of Sustainability & Environment at Waymo, said:Our shared fleet of EVs provide a massive opportunity to support the growth of clean energy on the electricity grid while expanding the circular economy. Through this partnership, we can repurpose our batteries for local grid storage and ensure our batteries continue to provide economic and environmental value to the community long after they’ve retired from the road.
The announcement pointed to the increasing levels of renewable energy production in parts of the US, which can create periods of excess supply. Grid-scale storage systems are used to manage these fluctuations by storing energy during periods of high generation and supplying it during peak demand.
Initial deployments are planned in Texas and California, where renewable energy capacity and storage requirements are expanding. Further rollout will depend on battery availability and project development timelines.
Freeman Hall, CEO of B2U Storage Solutions said:This agreement marks a significant milestone in B2U’s mission to provide integrated repurposing services to the automotive industry. By extending the use of these batteries as grid storage, we are monetising the full potential of EV batteries, now providing crucial stability to the power grid as energy demand continues to grow.
