AI's power crunch could get a boost from old EV batteries

Redwood Materials, led by ex-Tesla CTO JB Straubel, is repurposing used electric vehicle batteries to store electricity for grids and AI data centers amid rising US power demand. This approach addresses the challenge of meeting surging electricity needs from AI and electrification without waiting for new grid infrastructure. With millions of EV batteries reaching end-of-life, they offer a valuable resource for energy storage to balance supply and demand.
