Pulling The Weight of Heavy Truck Decarbonization
Exploring Pathways to Decarbonize Bulk Material Hauling in MiningDownload the report below
Haul trucks already emit 68 MtCO2 per year and account for 30%–50% of a mine’s total energy use. Trucking demand at mine sites is expected to grow substantially, driven by increased demand for minerals coupled with higher total ton-km to deliver mined materials to processing plants. Replacing diesel hauling fleets with low-carbon options is essential for companies looking to decarbonize their operations.
But, with the majority of open-pit mines still operated with diesel haul trucks, very little has happened in the past decade with regard to decarbonization on a global portfolio level. To stay on track for the 2010–2050 target of 58% reduction set by the International Energy Agency in 2014, an adjusted target in many cases implies greater than 100% decarbonization, or a nonlinear pathway. The nonlinear pathway that achieves this target requires a full decarbonization of hauling with disruptive technology no later than 2040.
Counterintuitively, near-term investment in partial decarbonization only has a three- to five-year impact on the timing for when the more disruptive technology is needed. To meet the 2050 target, mining companies need to front-load transformation of hauling at assets where already available non-truck-based solutions are more applicable, while aggressively pursuing R&D and policy support for new disruptive solutions.
This report explores six decarbonization options of varying abatement potentials and technology readiness.
