Walmart employees look over an X15N engine — made at the Cummins Inc. Jamestown Engine Plant — before the truck makes its way on a field test from Indiana to California, where it will featured at the Advanced Clean Transportation (ACT) Expo in Anaheim, Calif., from May 1-4.

The Cummins Jamestown Engine Plant’s 15-liter compressed natural gas engine is gettig a field test.

Walmart, Chevron and Cummins launched a program Tuesday through which the Arkansas-based retailer will incorporate the first North American 15-liter compressed natural gas engine into Walmart’s private fleet. The X15N engine is supplied by Cummins and fueled by Chevron with compressed natural gas linked to renewable natural gas. The Walmart truck will make its inaugural trip from Indiana to California, making pit stops along the way to refuel at Chevron stations.

Cummins is investing $452 million to have the necessary equipment in place at its Jamestown Engine Plant to upgrade its 998,000 square-foot facility in Western New York to produce the industry’s first fuel-agnostic internal combustion engine platform that leverages a range of lower carbon fuel types. The X15N is part of the new fuel-agnostic 15-liter engine platform produced at the Jamestown Engine Plant.

Cummins customers, including Walmart, Werner, Matheson, and National Ready Mix, among others, are beginning to test the very first engines of the fuel agnostic platform, the X15N. The program announced Tuesday is the first field test unit later in April to take part in the field test of this industry-first, 15-liter advanced engine platform running on renewable natural gas.

While trucking has historically relied on diesel to fuel its engines, a move toward renewable natural gas is an important step toward lowering fleet emissions. Renewable natural gas is produced when biomethane from decomposing organic matter – such as cow manure or landfill waste – is captured, treated and processed into natural gas. Methane that is not captured and processed is 25 times more potent than carbon dioxide (CO2) at trapping heat within the atmosphere leading to climate change.

“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.”

Last year, Walmart announced several initiatives among its Class 8 transportation fleet as the retailer pursues its goal to achieve zero emissions across global operations by 2040. Company officials said the introduction of this CNG-powered truck is an important milestone in the retailer’s journey.

“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,” said Fernando Cortes, senior vice president of transportation at Walmart. “We are proud to team with Cummins and Chevron to develop industry-leading advancements that pave toward a lower carbon future.”

At the end of the road, it will be featured at the Advanced Clean Transportation (ACT) Expo in Anaheim, Calif., on May 1-4, where the truck and engine will be on display and available for attendees to jump in and take a ride.

“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, the industry, and customers who rely on all of our products to advance a lower carbon economy.”
