The report explores pathways to decarbonize bulk material hauling in mining. The authors suggest that the challenge of decarbonizing heavy truck haulage is significant, and there are several options for decarbonization, including natural gas, battery electric vehicles, and hydrogen fuel cell vehicles. The authors also highlight the importance of collaboration between industry, government, and research institutions to accelerate the adoption of decarbonization solutions. The report is published by Rocky Mountain Institute, an independent nonprofit that aims to create a clean, prosperous, and secure low-carbon future.
