GM teams up with Redwood Materials to power data centers with EV batteries

General Motors (GM) has partnered with Redwood Materials to repurpose both new and used electric vehicle (EV) batteries for stationary energy storage applications. Redwood Materials processes these batteries by retaining many packs intact—rather than fully recycling them—because testing shows many cells still have significant usable life. These second-life batteries have been integrated into a 12-megawatt microgrid at Redwood’s headquarters in Sparks, Nevada, which supplies electricity to a nearby 2,000 GPU data center operated by Crusoe. The microgrid is powered by solar panels, enabling the storage of excess renewable energy for later use, and is part of Redwood’s broader initiative launched publicly in June to repurpose EV batteries for grid-scale energy storage. Redwood Materials currently recovers about 70% of used or discarded batteries in the U.S. and aims to deploy 20 gigawatt-hours of energy storage capacity by 2028. The company’s ability to integrate various battery packs from different manufacturers and chemistries may
