INNIO Group and the Net Zero Innovation Hub for Data Centers have completed a 3 MW demonstration of data center backup power using 100% hydrogen-fueled gas engines. The testing was conducted at INNIO’s research facility, with technical experts from Microsoft, Google, and Data4 present to witness live operation and assess performance against data center requirements.
The demo used a hydrogen-fueled Jenbacher engine in what INNIO describes as a 3 MW-class configuration. INNIO’s Jenbacher platform is known for rapid start-up, transient response, and stable operation on natural gas, and the companies said those characteristics were demonstrated while running on hydrogen.
To approximate real facility behavior, the test incorporated “various AI load profiles” and large, rapid load fluctuations intended to simulate data center load dynamics. INNIO said the engine met response profiles required for mission-critical operations during the 3 MW-class testing, and the attending teams from Microsoft, Google, and Data4 assessed results against operational requirements.
For data center engineers, the interesting part isn’t the fuel switch by itself—it’s whether a hydrogen-fueled engine can deliver the step-load response and ride-through characteristics operators expect from standby generation, without creating new integration headaches upstream in fuel storage, safety systems, and controls. A single 3 MW test doesn’t answer deployment questions on its own, but it does put transient performance front and center, where many low-carbon backup concepts struggle when you move past steady-state numbers.
The work was carried out through the Hub’s structured process for validating technologies aimed at large-scale deployment. Following a global Request for Information (RFI) focused on low-carbon backup solutions, the Hub selected hydrogen and clean fuels as a pathway to substitute for diesel backup generators, then chose INNIO’s Jenbacher gas engine technology for MW-scale validation. The Hub lists Data4, Google, Microsoft, Schneider Electric, and Vertiv among its industry partners.
“This validation test demonstrates that INNIO’s technology delivers the transient performance, resilience, and flexibility data centers require, even when operating on 100% hydrogen,” said Dr. Olaf Berlien, President and CEO of INNIO Group. Alberto Ravagni, CEO of the Net Zero Innovation Hub for Data Centers, added: “This successful test validates not only a scalable clean back-up solution, but also the novel collaborative Hub approach to accelerate the adoption of innovative solutions in the data center industry.”
INNIO Group and the Net Zero Innovation Hub for Data Centers said they plan to continue work on scaling the approach, including fuel availability, infrastructure, storage, permitting, dual-fuel capabilities, and integration into data center architectures.
