Next-gen KARNO^™ generator can operate on 20+ different fuel sources, including hydrogen, and initial testing indicates it’s expected to comply with current and foreseeable emissions standards

AUSTIN, Texas / May 02, 2023 / Business Wire / Hyliion Holdings Corp. (NYSE: HYLN) (“Hyliion”), a leader in electrified powertrain solutions for Class 8 commercial semi-trucks, today announced the unveiling of its groundbreaking Hypertruck KARNO demonstration vehicle at the Advanced Clean Transportation Expo (“ACT”) in Anaheim, California on May 2, 2023. The featured semi-truck employs a first-of-its-kind electric range extender powertrain that can be refueled with both hydrogen and natural gas.

“At Hyliion, we are delivering practical solutions that cater to fleets' current needs while continually developing cutting-edge products that seize the opportunities of tomorrow,” commented Thomas Healy, Founder and CEO of Hyliion. “While our focus remains on the 2023 production launch of the Hypertruck ERX™, a renewable natural gas electric range extender powertrain, we are also developing the Hypertruck KARNO as part of our transition to offer fleets fuel flexibility,” Healy added.

The KARNO generator is expected to show an improvement in fuel efficiency and a significantly lower emissions profile versus conventional generators. It will also be capable of operating on over 20 different fuels including hydrogen, natural gas, propane, ammonia and conventional fuels.

Hyliion acquired the KARNO generator technology from GE Additive last August to provide a next-generation generator for integration into its powertrain platform and to be used for distributed grid stationary power applications. The KARNO technology is a linear motor heat generator that leverages advanced 3D metal printed components and proprietary flameless oxidation technology to produce clean electricity.

In ACT booth 6327, Hyliion will display the Hypertruck KARNO demo truck and offer comprehensive technology overviews. Additionally, Hyliion will feature the Hypertruck ERX powertrain solution as part of the expo’s ride & drive experience. Both the Hypertruck ERX system and Hypertruck KARNO leverage Hyliion’s state-of-the-art electric powertrain but offer distinct onboard power generation technologies.

The exhibited Hypertruck KARNO vehicle is intended for product demonstration at ACT Expo and will be subsequently used for continued development, testing and validation. This vehicle underscores Hyliion's commitment to a net-carbon-negative global commercial transportation industry.
