This battery recycling company is now cleaning up AI data centers

The event marked the launch of the company's new business line, Redwood Energy, which will initially repurpose (rather than recycle) batteries with years of remaining life to create renewable-powered microgrids. Such small-scale energy systems can operate on or off the larger electricity grid, providing electricity for businesses or communities. Redwood Materials says many of the batteries it takes in for processing retain more than half their capacity. "We can extract a lot more value from that material by using it as an energy storage project before recycling it," JB Straubel, Redwood's founder and chief executive, said at the event. This first microgrid, housed at the company's facility in the Tahoe Reno Industrial Center, is powered by solar panels and capable of generating 64 megawatt-hours of electricity, making it one of the nation's largest such systems.
