Hyliion has announced that its Karno Power Module, an electricity-generating system, has achieved 100 days of operation on a customer asset at its Cincinnati, Ohio facility without experiencing any unplanned downtime due to hardware issues. The company reports that this milestone was reached after rigorous testing under a variety of load conditions as part of ongoing validation and performance characterization for a customer.
According to Hyliion, the system underwent hundreds of start cycles and logged significant runtime during these 100 days, though not operating continuously. Throughout the process, Hyliion implemented software updates and system upgrades, reporting that the hardware showed robust reliability and required minimal maintenance. The company attributes the lack of unplanned hardware-related downtime to the system’s durable architecture and low-maintenance design.
The Karno Power Module uses additive manufacturing and is described as fuel-agnostic, supporting operation with multiple fuel sources. Hyliion states that the system is aimed at providing highly efficient, low-emissions power for applications including data centers, commercial and industrial facilities, and microgrids. The company notes continuing improvements to system controls, software, and operational efficiency as it prepares for broader commercial deployment in 2026.
“The completion of 100 days of operation without unplanned hardware-related downtime demonstrates the reliability and durability of our technology,” said Thomas Healy, Founder and CEO of Hyliion. “It also reflects the tremendous progress our team has made in advancing the KARNO platform toward commercial readiness and real-world deployment.”
Hyliion identifies data centers as a key target market for the Karno Power Module, alongside commercial, industrial, and microgrid applications. The technology’s robustness and ability to operate across different load conditions are cited as advantages for operators needing reliable, on-demand power.
