Incredibly proud to see @Hyliion’s KARNO™ Power Module named to @TIME’s Best Inventions of 2026! Years of engineering and development have brought us to this milestone. A tremendous recognition for our team, and I believe this is just the beginning! bit.ly/4yrQdpN

“Okay, so what’s in the box? How does the KARNO™ tech generate electricity?” The KARNO™ system is based on Stirling engine technology, a concept that dates back roughly 200 years. The basic idea is simple: trapped gas expands when it’s heated, and that movement can be used to generate electricity. Stirling engines have long had attractive characteristics like high efficiency and low maintenance, but historically they’ve been extremely difficult to manufacture. What changed? Additive manufacturing.

“What exactly did @Hyliion acquire from GE in 2022, and how mature was the KARNO™ technology at the time?” When we acquired KARNO™, the technology had already gone through roughly three generations of prototypes, but it was not yet ready for commercial applications. GE had been developing the technology since around 2017. Since the acquisition, our team has continued iterating on the design, bringing it through another generation or two to get to the commercial product we’re bringing to market today.
