Some Waymo robotaxis are already getting old, at least in terms of miles driven and technological evolution. The company is apparently at the point that it has old, used EV batteries it no longer needs. Now it is going to help community clean energy projects by supplying these used batteries to their efforts. “As communities work to build more sustainable electricity grids, Waymo is championing the circular economy by transforming our retired electric vehicle batteries into clean energy storage in areas where we operate,” Waymo shares. “Today, we’re proud to announce our new EV battery repurposing program in partnership with B2U Storage Solutions. This strategic collaboration ensures that once our batteries are retired from our all-electric fleet, they begin a vital second chapter: powering the local electricity grids,” Waymo added on Thursday. Waymo doesn’t hold its heart on its sleeve when it comes to cleantech. It doesn’t normally make a big show of how much it’s helping to cut emissions, that it uses only fully electric vehicles, etc. I assume the leadership and PR team are focused on seeming neutral on “political” matters (unfortunately, maintaining a stable, livable climate and clean air are seen as political matters these days). I assume they want the support of people of all political stripes — or at least don’t want to be obstructed by some of them. In any case, though, it’s great to see Waymo helping to cut CO2 emissions and pollution in more ways. “Through this partnership, our EV batteries are utilized for essential local infrastructure, further expanding upon the impact of our best-in-class maintenance program which significantly extends vehicle lifespan and durability. Rather than heading straight to recycling, our EV batteries will be given a second life,” Waymo adds. “As a leader in large-scale energy storage, B2U specializes in repurposing EV batteries—leveraging their patented technology to integrate EV batteries into grid-scale storage systems. These systems act as a vital reservoir, absorbing surplus renewable energy during midday peaks, and dispatching it back to the grid during periods of peak energy demand.” Getting back to my previous point, funny enough, Waymo highlights clean energy leadership from California and Texas here: “As of 2026, California is averaging 6.1 hours daily of 100% clean power, and Texas continues to lead the nation in new solar capacity. Expanding battery storage is critical to sustaining this growth. By repurposing our EV batteries, Waymo is helping bridge the gap between peak renewable production and the community’s energy needs. […] “Our partnership with B2U will deploy hundreds of megawatts of storage capacity across the grids serving our cities. This reinforces our commitment to clean energy while maximizing the positive environmental impact of our fully autonomous, all-electric fleet. Our first deployments will be focused on Texas and California, states in which Waymo operates a robust public service.” All great stuff. More reasons to love Waymo. The company has also put out a short video on the new partnership: “This agreement marks a significant milestone in B2U’s mission to provide integrated repurposing services to the automotive industry,” said Freeman Hall, CEO of B2U Storage Solutions. “By extending the use of these batteries as grid storage, we are monetizing the full potential of EV batteries, now providing crucial stability to the power grid as energy demand continues to grow.” “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,” said Adam Lenz, Head of Sustainability & Environment at Waymo. “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.” You can’t argue against any of this, can you?
