Walmart, Chevron Partner with Cummins on X15N Natural Gas Engine Field Test

The much anticipated 15-liter CNG-powered Walmart truck was on display at the Advanced Clean Transportation (ACT) Expo in Anaheim, California earlier this month. It was on its inaugural trip from Indiana to California, which concluded at the event.

The new groundbreaking X15N natural gas engine is manufactured by Cummins – the multinational company that designs, manufactures, and distributes engines, filtration, and power generation products. It is the first on the road in North America. Walmart recently began piloting five of the engines in its Class 8 fleet as part of its broader goals for sustainability.

During the journey, the truck stopped to refuel at Chevron’s compressed natural gas (CNG) stations that offer carbon negative renewable natural gas (RNG). In 2021, 98% of all on-road fuel used in natural gas vehicles in California was RNG. These stations are part of the extensive CNG fueling network that exists throughout California.

According to Cummins, fleets will have the opportunity to order factory-built Class 8 trucks with the Cummins X15N 15-liter engine in 2024, as PACCAR announced availability for both its Kenworth and Peterbilt brands. The Cummins X15N engine offers a range of at least 750 miles even when hauling 82,000-pound loads.

This partnership demonstrates the reliability and versatility of CNG truck and fueling technology. RNG is not a fossil fuel. It is made from organic waste, generated by a variety of sustainable and renewable sources, including wastewater treatment plants, food and green waste, landfills, dairies, farms, and forest management. It can also be produced as a byproduct of renewable hydrogen and sequestered CO2, a key strategy to store surplus renewable electricity.
