As part of its commitment to the demonstration of Cummins Inc.’s new 15-liter natural gas engine for heavy-duty trucks, Chevron U.S.A. Inc., a subsidiary of Chevron Corporation, has reached definitive agreements to supply renewable natural gas fuel to Walmart Inc.

Cummins will integrate the natural gas engine X15NTM, which runs on compressed natural gas (CNG), into Walmart’s heavy-duty trucks under the agreement. In California, Walmart will field-test the finished trucks in its distribution center after taking delivery, with Chevron providing renewable natural gas for the trucks.

“Chevron has positioned itself to help major fleet operators like Walmart in their efforts to decarbonize their transportation operations through the use of CNG linked to renewable natural gas,” said Andy Walz, president of Americas Fuels & Lubricants for Chevron.

The two companies expanded their memorandum of understanding in September 2021 to include new strategic priorities relating to renewable natural gas, first focusing on making it easier for fleets to transition to natural gas engines by improving fuel availability while helping them to reduce their lifecycle carbon intensity.
