Hyliion at NASA JPL: Rethinking Power Generation for Extreme Environments On May 14, 2026, Hyliion was invited to present the KARNO™ platform at the Interagency Advanced Power Group's Mechanical Working Group meeting, hosted at NASA's Jet Propulsion Laboratory in Pasadena, California. The IAPG convenes technical leaders from across the federal R&D community: NASA, the Department of War (Army, Navy, Air Force Research Laboratory, Space Force), the Department of Energy, Department of Transportation, and DARPA to share progress on advanced power, thermal management, and propulsion. This session's theme: Extreme Environments. It's the right theme for a conversation about KARNO. Bobby Cherian, SVP of Government Affairs at Hyliion, represented the company and walked through the foundational technology behind KARNO: a heat-powered linear generator built on Stirling-cycle thermodynamics and enabled by advanced metal additive manufacturing. The architecture is designed precisely for the conditions where conventional power generation breaks down from unmanned maritime vessels, forward operating bases and mobile command posts, nuclear heat conversion systems, and burst power and cryogenic cooling for directed energy platforms. “Across every challenge discussed today where conventional power generation falls short, Hyliion’s defense roadmap identifies solutions where we believe KARNO technology is uniquely positioned to step in and close the gap,” said Cherian. Thank you to NASA Glenn Research Center for the invitation to participate alongside the nation's leading government power and thermal management research community. The conversations that followed were exactly the kind this technology deserves. #KARNO #PowerGeneration #DefenseInnovation #LinearGenerators #NASA This work was sponsored by the Office of Naval Research through contract N00014-24-C-1305

What happens when power demand grows faster than the grid can respond? @ThomasHealyCEO joined Path To Zero to talk about the KARNO™ tech, distributed generation, and why flexible, on demand and on-site power is critical to the future of power generation.

Add transmix to the list. The off-spec mixture that forms where gasoline, diesel, and jet fuel meet in a pipeline normally gets trucked to a processor and distilled. The KARNO™ ran on it directly in a recent demonstration. No reprocessing. No hardware changes. Practical solutions to real world problems. #KARNO #FuelAgnostic #LinearGenerators #PowerGeneration #Midstream
