    Hyliion Hypertruck Karno Act Expo 2023 6452db3653c4d

    ANAHEIM, California—Hyliion Holdings Corp. unveiled its Hypertruck Karno demonstration vehicle here at the Advanced Clean Transportation Expo. The featured semi-truck employs an 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,” noted 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.”

    The Karno generator is expected to show an improvement in fuel efficiency and a lower emissions profile versus conventional generators. According to Hyliion, it will also be capable of operating on more than 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.

    The exhibited Hypertruck Karno vehicle is intended for product demonstration at ACT Expo and will be subsequently used for continued development, testing, and validation.
