Hyliion announced that it will be acquiring a fuel-agnostic generator from General Electric that is expected to drastically cut emissions and increase fuel efficiency by up to 20% in its hybrid ERX.

Hyliion CEO Thomas Healy told CCJ that GE approached his Texas-based company about a year ago with the Karno generator which Healy said is lighter and smaller than current generators on the market and is capable of running on both gaseous and conventional fuels.

The unit relies on flameless oxidation to produce heat which in turn is used to generate electricity. In a lab setting, flameless oxidation has shown up to a 20% gain in fuel efficiency.

“GE has been doing this as a skunkworks kind of project,” Healy said. “They're using learnings from jet engines because it actually came out of their aviation division.”
