KIT review advances caloric cooling for sustainable systems

Karlsruhe Institute of Technology (KIT) has published a review on caloric cooling technologies and their path toward practical deployment.

• The Review, led by Dr. Jingyuan Xu of KIT’s Institute of Microstructure Technology (IMT) and published in Nature / Nat Energy, surveys progress in magnetic, electric, pressure, and strain-based cooling systems and outlines remaining technical challenges.
• The article says current prototypes have reached more than three kilowatts for magnetic-field systems and over one kilowatt for mechanically driven prototypes; it also notes the growing cooling demand from AI data centers and the broader need for lower-emission cooling.
• Contact details provided in the press release include Christian Könemann and Dr. Martin Heidelberger at KIT; the release date is 30.10.2026.
