Hyliion Holdings Corp. has successfully completed the initial performance testing phase of its KARNO™ Power Module for U.S. Navy applications, demonstrating strong load-following capability and reliability under demanding conditions.

Funded by the Office of Naval Research, the testing paves the way for further evaluations, including operations under simulated ship-motion and dynamic load profiles, before potential at-sea demonstrations. The KARNO system is designed for quiet operation, fuel flexibility, and minimal maintenance, aligning with military energy requirements.
