Glacian Technologies is a Penn State University spin-off building AI software that optimizes cooling systems in data centers. Its technology combines physics-based models of cooling equipment with machine learning to reduce the electricity that cooling consumes, freeing up power capacity for AI compute without utility permits or new construction. The company says its approach rests on more than a decade of research backed by over $8 million in competitive government and private research grants, and it reports demonstrated cooling energy savings of 53% at a Florida data center and 74% at a Massachusetts data center.
