Hyliion acquires KARNO fuel-agnostic generator expertise from GE for range-extended electrical truck


Hyliion, a developer of electrified powertrain options for Class 8 business autos (earlier publish), has entered right into a definitive settlement to amass a brand new fuel-agnostic generator (KARNO) from GE Additive for its range-extended series-hybrid powertrain. The Hyliion KARNO resolution provides a next-generation powertrain choice between the CNG/RNG-fueled generator used within the Hypertruck ERX and the long run Hypertruck Gas Cell.


The KARNO generator emerged out of GE’s long-running R&D investments in metallic additive manufacturing throughout a number of industries and in areas akin to generator thermal and efficiency design. Preliminary testing signifies the KARNO generator is predicted to adjust to all present and foreseeable emissions requirements, particularly from CARB and EPA, even when using typical fuels.

The expertise is predicted to attain a 20%+ effectivity enchancment over as we speak’s typical mills and may very well be extra environment friendly than most obtainable gas cells. These effectivity enhancements ought to, in flip, allow gas value reductions and improved car vary. The expertise must also present for important reductions in noise, vibration, shifting elements and upkeep as in comparison with present combustion engines.

The KARNO energy system might be able to working on over 20 completely different fuels together with hydrogen, pure fuel, propane, ammonia and standard fuels. The expertise makes use of warmth to drive a sealed linear generator to provide electrical energy. The warmth is produced by reacting fuels by way of flameless oxidation or different warmth sources together with renewables.



Hyliion will leverage the KARNO as the subsequent era generator onboard the Hypertruck, creating an answer that can function on varied gas sources which are obtainable as we speak, whereas remaining future-proofed to run on hydrogen when it turns into broadly accessible.

—Thomas Healy, Founder and CEO of Hyliion

In late 2023, Hyliion plans to first launch the Hypertruck ERX powertrain, which leverages a pure fuel engine because the generator onboard. Within the years following, Hyliion plans to launch the Hypertruck KARNO, its fuel-agnostic variant, as part two within the Hyliion journey to a hydrogen-based future. Hyliion may even discover different adjoining markets to leverage this expertise for value financial savings and emissions reductions.


The transaction is topic to customary closing circumstances and is predicted to shut by the tip of Q3 2022. With an acquisition worth of ~$37 million, GE will obtain $15 million in money and roughly $22 million in Hyliion inventory. Hyliion will purchase the generator expertise and combine the Cincinnati-based engineering crew that created the KARNO system into Hyliion.
