Team looking to tap underground ‘thermal batteries’ to cool AI Data centers and save water – Illinois News Bureau

A research team is exploring the use of underground “thermal batteries”—subsurface geological formations—as a cooling solution for artificial intelligence data centers while reducing water consumption. The approach aims to leverage stable underground temperatures to dissipate heat generated by computing equipment, potentially addressing both the cooling and water scarcity challenges associated with large-scale AI infrastructure. The project represents an effort to develop more sustainable operational methods for power-intensive data center facilities.
