Introduction
Imagine a future where discarded electric vehicle batteries find a second life—not in recycling plants, but powering the very backbone of AI: data centers. That’s precisely the vision behind Redwood Energy’s latest venture. Founded by Tesla co-founder JB Straubel, Redwood Materials is turning EV waste into a sustainable energy solution for the booming AI era.
Why It Matters
The rise of AI is pushing electricity demand through the roof—and our current power grids aren’t equipped for it. Data centers alone could consume up to 12% of U.S. electricity by 2028. Building new grid infrastructure or waiting for renewables isn’t enough. We need fast, reliable, and cost-effective solutions—enter second-life EV batteries.
What Redwood Is Doing
Redwood Materials repurposes batteries that still have 50–80% capacity, redirecting them from recycling to reuse in energy storage systems Business Insiderredwoodmaterials.com. Their new business unit, Redwood Energy, deploys these batteries in modular, low-cost systems that are faster to install than brand-new alternatives redwoodmaterials.com Business Insider.
Real-World Example: The Nevada Microgrid
At their Sparks, Nevada campus, Redwood built a groundbreaking microgrid: 12 MW capacity with 63 MWh storage, powered entirely by used EV batteries and solar panels Data Center Frontier Business Insider The Verge. This microgrid supports Crusoe’s GPU-heavy data center and stands as North America’s largest second-life battery installation Business InsiderThe Verge.
The Benefits—All Around
Cost-Effective: Systems cost significantly less than new lithium-ion installations deepwatermgmt.comBusinessScaling the Future Insider.
Fast Deployment: Modular setup means you can get power online in weeks, not years deepwatermgmt.comredwoodmaterials.com.
Eco-friendly: Keeps valuable materials in motion and cuts carbon footprint.
Resilient & Flexible: Works off-grid, can integrate with renewables, and supports peak load balancing Data Center Frontierredwoodmaterials.com.
Scaling the Future
Processing over 20 GWh of used batteries annually (about 90% of North America’s recycling stream), Redwood is well-positioned to scale fast Business Insiderredwoodmaterials.com. They aim to deploy 20 GWh of storage by 2028, enough to keep pace with growing AI infrastructure demand Business Insider.
Further, their partnership with GM—tapping into new and second-life batteries—showcases how mainstream automakers are supporting grid resilience. The Verge Business Insider.
Conclusion
Redwood Energy isn’t just a smart solution—it’s a blueprint for how we can build an energy ecosystem that’s cleaner, faster, and cheaper. As AI continues to surge, repurposing EV batteries may prove essential to powering the future efficiently.
