Trillium to fuel Werner on Cummins X15N engine field testing

May 23, 2023
Fuel provider Trillium will provide Werner with the natural gas used to fuel Cummins' new X15N RNG engine.

Trillium Energy Solutions, a member of Love’s Family of Companies, will supply Werner Enterprises with renewable natural gas (RNG) as part of field trials of the new Cummins X15N engine, the manufacturer’s 15-liter natural gas engine.

As the exclusive RNG fueling supplier for Werner during trials to validate commercial production of the engine, Trillium will fuel Werner’s Peterbilt Model 579 field trial truck with RNG from its Omaha, Nebraska and Rockford, Illinois stations.

“Working with partners like Trillium to test the X15N while utilizing RNG gives Werner valuable real-world data that helps us validate these engines prior to a wider adoption into our fleet,” said Chad Dittberner, Werner’s SVP of dedicated services. “Trillium has been helpful in this process, and we look forward to expanding adoption of these clean fuels and advanced technologies in our fleet.”

Werner is one of the first fleets to test RNG in the Cummins X15N engine, with a goal to lower fleet emissions, increase performance, and reduce downtime, according to a Trillium press release.

“Love’s and Trillium have a successful relationship with Werner, both with fueling their compressed natural gas (CNG) trucks and now supplying RNG for field trials of the Cummins X15N engine,” said Marc Rowe, Trillium GM of fuel sales. “The use of low- and even negative-carbon fuel is an important element for any fleet seeking to reduce its emissions. Love’s and Trillium are continuing to expand our retail CNG station footprint by adding more locations for our customers in 2023 and beyond in several markets in the U.S.”
