Transport is a major source of emissions in Australia, with on-road diesel vehicles driving the increase in emissions. The growing number of diesel vehicles poses a challenge in decarbonizing the transport sector. A study evaluating the lifecycle emissions of low-emission trucks in Australia compared electric and hydrogen trucks. The research found electric trucks to be more efficient in decarbonizing road freight, with hydrogen trucks having higher emissions intensity in some cases. The study analyzed different scenarios with varying energy mixes and adoption rates, showing that high rates of renewable energy adoption could significantly reduce emissions. Challenges in cutting emissions from manufacturing, maintenance, and disposal were highlighted, with electric trucks having higher emissions in these phases compared to hydrogen trucks. The findings emphasize the importance of considering the full lifecycle of trucks to assess their overall carbon footprint. The industry faces challenges in transitioning to electric and hydrogen trucks, as highlighted by a survey of trucking organizations showing varying levels of knowledge on these technologies. Overall, the study provides insights into the potential for electric trucks to play a key role in decarbonizing road freight and the challenges that need to be addressed in the transition to more sustainable transport options.
