The immense power demands of AI data centers are straining electricity grids, prompting a search for solutions. One promising approach involves repurposing retired electric vehicle batteries, which retain significant capacity and are well-suited for stationary energy storage. These batteries can charge during off-peak hours and discharge during peak AI workloads, acting as a buffer to reduce costs and grid stress. Companies like Re-Teck are positioning themselves to supply these repurposed batteries to AI data center operators, while projects like Redwood Materials' microgrid powering a Crusoe Energy data center demonstrate the viability of this concept.
