Queensland’s road-freight fleet is responsible for approximately 25% of greenhouse gas emissions from the transport sector, and these emissions are projected to keep growing until at least 2030. Due to their high potential to reduce emissions, Low and Zero Emissions Truck Technologies (LZETs) are reviewed in detail to understand the competitiveness of different LZETs compared to diesel technology today, in the context of Queensland’s 2050 net-zero emissions target. A feasibility assessment is conducted for deploying LZETs on a set of sample road-freight routes across Queensland. The sample represents a cross-section of popular freight routes varying in terms of geographic location, climatic conditions, terrain, and total journey distance. Candidate (‘typical’) battery electric trucks (BET) and hydrogen fuel cell trucks (HFCT) are simulated for driving on each route to approximate energy consumption, and in …
