The first 15-litre compressed natural gas (CNG) engine on North American roads, Walmart, Cummins, and Chevron are taking steps towards their goal of zero-emissions transportation.


Walmart, in collaboration with Cummins and Chevron, is taking a significant step towards achieving its goal of a zero-emissions transportation fleet with the introduction of the first North American, and the first of five, 15-litre compressed natural gas (CNG) engined trucks into its fleet. The X15N™ engine, supplied by Cummins and fueled by Chevron with renewable natural gas (RNG), will power a Walmart truck on its inaugural trip from Indiana to California, with pit stops at Chevron stations along the way.

As part of its commitment to achieving zero emissions across its global operations by 2040, Walmart has been implementing several first-of-their-kind initiatives in its Class 8 heavy duty truck fleet. The introduction of this CNG-powered truck marks a significant milestone in Walmart’s sustainability journey.

Fernando Cortes, Senior Vice President of Transportation at Walmart, said, “Walmart transportation is focused on the continuous piloting of solutions that aren’t just changing the industry, but are having a lasting impact on the world. We are proud to team with Cummins and Chevron to develop industry-leading advancements that pave toward a lower carbon future.”

Renewable natural gas is produced by capturing and treating biomethane from decomposing organic matter, such as cow manure or landfill waste, and processing it into natural gas. “Working with partners like Walmart to test new products like the X15N gives Cummins valuable real-world data that helps us validate our engines prior to moving into full production,” said Puneet Jhawar, General Manager - Spark Ignited Products for Cummins. “Chevron has also been very helpful in our test; to help increase CNG fuel availability that will enable adoption of alternate technologies faster.”

The CNG-powered Walmart truck will be featured at the Advanced Clean Transportation (ACT) Expo in Anaheim, California, from May 1-4, where it will be on display and available for attendees to experience firsthand.

“Chevron is constantly pursuing solutions that drive progress toward a lower carbon future,” said Andy Walz, Chevron’s President of Americas Products. “Partnering with Walmart and Cummins on the road trip and demonstration can help us deliver that progress today for the transportation industry and customers who rely on all of our products to advance a lower carbon economy.”
