Nate Weger is the co-founder and CTO of Calectra, where he is working to electrify high-temperature industrial process heat. Calectra’s technology is based on his Ph.D. research at the Lawrence Berkeley National Laboratory. He specializes in heat transfer, with an emphasis on high-temperature energy systems, and has extensive experience decarbonizing industrial technologies. Weger has degrees in mechanical engineering from UC Berkeley (Ph.D.) and the University of Iowa (B.S.E.).

With its patent-pending thermal storage technology, Calectra provides zero-carbon, low-cost industrial process heat up to 1,600°C. Calectra converts low-cost, intermittent renewable electricity into high-temperature heat, stores it for up to days at a time, and delivers it to retrofitted industrial processes using a simple, inexpensive air-based heat transfer system.
