Vale SA has entered into a partnership with Cummins Inc. and Komatsu to advance a joint Dual Fuel Program aimed at developing large truck engines powered by both ethanol and diesel. This collaboration marks a significant step toward reducing greenhouse gas emissions in the mining sector by retrofitting existing Komatsu haul trucks to operate on up to 70% ethanol. The innovative project is expected to lower CO2 emissions by up to 70% while maintaining productivity and performance. Cummins is testing the QSK60 engine at their Seymour Engine Plant, with field trials anticipated to begin in 2026. This initiative aligns with Vale's goal to cut its greenhouse gas emissions by 33% by 2030 as part of its broader decarbonization strategy.
