The KARNO generator leverages additive manufacturing for production of many of its components including all critical heat exchangers and thermodynamics systems. This innovative manufacturing process not only enhances the precision and quality of these components but also contributes to the overall improved efficiency of the generator.

“We are thrilled to begin printing the production-intent design of the KARNO generator which showcases another major step on our path to deploying this technology with customers,” said Thomas Healy, Founder and CEO of Hyliion. “The initial 200 kW BETA units will operate at our Cincinnati, Ohio, development facility in order to confirm the superior efficiency levels, ultra-low emissions, and long runtime between maintenance.”

This significant achievement highlights that Hyliion has completed designs of the major components of the BETA version of the KARNO generator, and it is now ready for final validation. Throughout 2024, Hyliion will be completing testing and verification of the BETA generator to prepare for initial deployments to early adopters of the technology later this year. Hyliion will continue to improve the system design and leverage the flexible capabilities of additive manufacturing. Hyliion is well-positioned to meet the milestones previously outlined for the completion of BETA development by the first half of 2024.

Today, Hyliion’s Founder and CEO, Thomas Healy, will be a featured speaker on "Modern Electrification Needs and the Rise of Distributed Power Generation" at the POWERGEN International Conference in New Orleans, LA.
