Hyliion has successfully operated its KARNO reactor through four distinct fuel transitions—natural gas, hydrogen, natural gas, diesel, and back to natural gas—in one uninterrupted run without making any hardware changes.
The demonstration, conducted at Hyliion's research laboratory, underscores the flexibility and potential of the KARNO reactor for future clean energy applications. By enabling such fuel versatility, Hyliion aims to advance next-generation power solutions adaptable to a changing energy landscape.
Earlier this year, Hyliion called for final votes as its KARNO Power Module competed for the CSE 2026 Product of the Year award before the April 30 deadline, according to a previous report. The company continues to position the KARNO technology at the forefront of clean energy innovation through ongoing demonstrations and industry recognition. No further details about the outcome of the award race have been released.
