Hyliion showcased its KARNO Power Module’s ability to switch between natural gas and propane while the unit was under load on November 17 2025 in Austin, Texas. The demonstration proved that the module can maintain continuous power output without any interruption or hardware modification, a key feature that underpins the company’s claim of fuel‑agnostic flexibility.
The KARNO platform is engineered to run on more than 20 different fuels, from natural gas and propane to biogas and hydrogen. The real‑time switching capability eliminates the need for separate hardware for each fuel type, reducing capital costs and simplifying deployment for customers who rely on locally available energy sources.
Hyliion’s focus on the KARNO generator follows a strategic decision in late 2023 to wind down its electric‑powertrain business. The company now reports a pipeline of nearly 500 non‑binding letters of intent for KARNO cores across data‑center, electric‑vehicle charging, and military applications, underscoring strong market interest in the technology’s low‑emission, high‑efficiency profile.
While the original article cited a 2025 launch for 200 kW units, more recent guidance indicates full commercialization will occur in 2026, with initial customer deliveries expected by the end of 2025. This adjustment reflects the time required to scale production and meet the growing demand reflected in the LOI pipeline.
Financially, Hyliion posted a third‑quarter 2025 net loss of $13.3 million, up from $11.2 million in the same quarter of 2024. Year‑to‑date revenue for the first nine months of 2025 was $2.8 million, primarily from research‑and‑development services for the U.S. Navy, compared with no revenue in the same period of 2024. The company’s cash balance stood at $164.7 million, providing a runway to fund ongoing R&D and the ramp‑up of KARNO production.
The fuel‑agnostic design positions Hyliion against conventional diesel generators and emerging fuel‑cell solutions, offering customers the flexibility to choose the most cost‑effective or readily available fuel while maintaining near‑zero emissions. CEO Thomas Healy emphasized this advantage, stating, “The need for reliable, dispatchable power is not waiting for a perfect fuel. It requires flexibility.” The company’s strategic focus, strong customer pipeline, and substantial cash reserves suggest a clear path toward commercializing the KARNO platform, despite current net losses and the need for continued investment in R&D.
