Hyliion Awarded US Government Contract for Game-Changing KARNO Generator for the US Navy

AUSTIN, Texas--(BUSINESS WIRE)-- Hyliion Holdings Corp. (NYSE: HYLN) ("Hyliion"), a developer of sustainable electricity-producing technology, has been awarded a $15+ million contract by the Office of Naval Research (ONR) to develop its groundbreaking KARNO ^TM generator for Navy ships and stationary power applications.

Upon successful validation and demonstration, the Hyliion KARNO generator could be used as a power system in future platforms, providing US Naval operations with scalability and flexibility while significantly reducing maintenance, emissions, and fuel consumption.

"At Hyliion, we are dedicated to delivering innovative power generation solutions that prioritize our customers' need for efficiency and reliability," said Thomas Healy, Founder and CEO of Hyliion. "This new partnership with the ONR is a testament to the performance and potential of our KARNO generator technology. We're incredibly proud to contribute to the future of the US military and help them achieve their power generation goals."

The KARNO generator is an innovative linear generation system powered by heat and enabled by 3D metal printing. Its hermetically sealed architecture, with only one moving part per shaft, is designed for maintenance-free operation over long running hours. The generator's efficiency, low maintenance, and quiet operation make it ideal for powering naval vessels.

This contract aligns perfectly with the ONR's strategic objective to leverage advanced technology for reducing carbon footprint and enhancing operational efficiency. The KARNO generator is highly versatile, providing adaptable power solutions to meet the unique demands of US Naval operations in maritime environments. Similarly, with its flexibility and form factor, the KARNO generator can potentially meet additional US Defense needs for reliable power in stationary applications without compromising on economics and emissions footprint.
