INNIO Demonstrates 3 MW Hydrogen Engine for Data Center Backup Power

INNIO Group and the Net Zero Innovation Hub for Data Centers completed a demonstration of a 3 MW hydrogen-fueled Jenbacher Hydrogen Engine at INNIO's research facility in Jenbach, Austria. The engine operated on 100% hydrogen and responded to real-world data center load profiles, including AI-simulated power surges.

The engine successfully transitioned from zero to full power output in seconds, matching the response rates required for backup power applications. Engineers retrofitted INNIO's Jenbacher platform with upgraded injection systems, cooling circuits, and combustion chambers designed for pure hydrogen operation, resulting in emissions-free functionality without compromising mechanical performance.

The demonstration included representatives from Microsoft, Google, and Data4, who participated in setting performance and integration standards. INNIO has committed to a green hydrogen supply agreement for the Jenbach facility starting in 2025 and joined the Science Based Targets initiative in 2021, pledging to halve upstream emissions by 2030.

Challenges remain, including hydrogen fuel availability, on-site storage requirements, permitting complexities, and higher costs compared to diesel. Additionally, INNIO is exploring dual-role engine designs capable of serving both backup and prime power applications.
