Werner Integrating Cummins Natural Gas and Hydrogen Internal Combustion Engines


Werner Enterprises will begin validation and integration of Cummins Inc.’s recently announced 15-liter natural gas and 15-liter hydrogen internal combustion engines in its vehicles.

Cummins will begin integrating these new powertrains in Werner trucks in the second half of 2022, starting with the 15-liter natural gas product.

“Werner is a transportation leader focused on reducing its carbon footprint, and Cummins is uniquely positioned to help provide low carbon options successfully and seamlessly using multiple power solutions,” says Srikanth Padmanabhan, vice president and president of Engine Business at Cummins. “Our solutions include our newest heavy-duty natural gas engine and our heavy-duty hydrogen ICE engine currently being developed. Our broad range of powertrain solutions from advanced diesel, natural gas, hydrogen to electrification allows Cummins to provide multiple options that meet our customers’ specific business needs and sustainability targets today. The next generation Cummins powertrains will provide a clear path to transition towards a zero-emission future.”

The 15-liter natural gas engine announced in October 2021 can be paired with a Cummins Eaton Automated Transmission Technologies Endurant HD Transmission and Cummins Fuel Delivery System, ensuring a purpose-built and fully integrated natural gas powertrain. Other transmission pairings will be available at launch for specialized applications. The 15-liter engine will offer ratings up to 500 horsepower and 1,850 ft-lbs of torque, while not requiring selective catalytic reduction (SCR) to meet 2024 California or Environmental Protection Agency emission standards, providing a potentially carbon-negative solution when powered with renewable natural gas (RNG).

“The options Cummins is providing align with our longstanding focus on sustainability and reducing our carbon footprint,” mentions Derek Leathers, chairman, president and CEO at Werner Enterprises. “They understand the priority we place on using technology to minimize our impact on the environment. By being proactive now, we are ensuring a better future for everyone, and I look forward to this collaborative effort.”

“This collaboration will combine the extensive experience and expertise of both our companies to provide Werner’s fleet with a safe and reliable solution that will help them meet their sustainability and operational targets while providing Cummins valuable operational and performance data to help us optimize our product offerings,” comments Amy Boerger, vice president and general manager at North America at Cummins. “These collaborations allow us to refine and optimize our technologies to make the shift to zero-emissions commercial transportation solutions across diverse markets much more quickly.”

Hydrogen engines offer OEMs and end-users the benefit of adaptability by continuing to use familiar mechanical drivelines with vehicle and equipment integration. This mirrors current powertrains while continuing to provide the power and capability for meeting application needs. Additionally, the 15-liter hydrogen engine can use zero-carbon green hydrogen fuel, produced by Cummins-manufactured electrolyzers. The projected investment in renewable hydrogen production globally will provide a growing opportunity for the deployment of hydrogen-powered fleets utilizing either Cummins fuel cell or engine power.
