Rolls-Royce Delivers mtu Power Generators with Environmental Product Declarations

Rolls-Royce supplied mtu-brand emergency power generators, verified with environmental product declarations (EPDs), to a European data center operator for the first time. The company partnered with Sphera to develop externally verified EPDs for emergency power generators, publishing recorded data in the international EPD system, Environdec. The EPDs document the complete environmental lifecycle of the mtu 16V4000 DS2500 and 10V1600 systems, including raw material extraction, production and use, and end-of-life recycling.

“With these environmental product declarations, we set a new industry standard for environmental transparency in the field of energy systems,” said Tobias Ostermaier, President of Stationary Power Solutions, Rolls-Royce Power Systems. “This is our response to growing demand from our customers, and we are actively supporting them in reducing their carbon footprint. Our EPDs create transparency for customers, authorities, and partners—and prove that sustainability is measurable and verifiable.”

This newly certified service offering provides extended maintenance intervals: Instead of monthly reviews, operators must only test their emergency power systems on a quarterly basis. The minimized check-in schedule significantly reduces both costs and emissions. The EPD International System is an independent, globally recognized organization based on the ISO 14025 and EN 50693 standards. Registered declarations contain intricate data on resource consumption, emissions, waste generation, and recyclability.

For Rolls-Royce’s power generators, the EPDs outline all phases of the product lifecycle—from supply chain to transport, assembly and operation, to maintenance and decommissioning. The lifecycle assessment data was gathered by Sphera, while Rolls-Royce contributed real production and operating data from its manufacturing facilities and suppliers.

Currently, mtu emergency power generators are approved for sustainable fuel operations with hydrotreated vegetable oil (HVO) and additional e-fuels. HVO serves as a full replacement for fossil diesel without technical modifications. Modern mtu exhaust gas aftertreatment, in combination with sustainable fuels, reduces CO₂, NOx, and particulate emissions by more than 90%.

Ensuring Production Capacity

This week, AVK and Rolls-Royce signed a long-term framework agreement that secures production capacity for mtu Series 4000 emergency power generators over a five-year period. The contract complements a related agreement between AVK and Landmark Power Holdings to develop and install customized, low-carbon power solutions for data centers in the United Kingdom.

Per the data center agreement:

• Rolls-Royce supplies mtu-brand gas engines
• Landmark Power Holdings integrates its FLEXPOWER PLUS carbon-capture technology
• AVK contributes its microgrid experience via design, EPC, and maintenance work

With these technologies and services, the partners are establishing a system that generates electricity while filtering CO₂ from the engines’ exhaust gases—a key aspect in decarbonizing the growing data center industry. The contract also provides Rolls-Royce with additional power capacity in the data center market and furthers the joint development of HVO-compatible solutions.

AVK supplies complete critical power solutions equipped with mtu Series 2000 and 4000 diesel engines, with power outputs ranging between 825 – 4,000 kVA. The company installs and then maintains these systems throughout their service lifecycles, and, in the past 10 years, Rolls-Royce has delivered 600 mtu gensets to AVK. For over 20 years, Rolls-Royce’s mtu gas engines have served as the primary emergency power system at AVK sites. Data centers must retain data and keep computing power available 24/7—even during public grid failures—so an emergency power system is always required.
