The global transport industry is currently debating the best 'green' power source for heavy vehicles, with options like electric batteries, hydrogen fuel-cell technology, hybrid trucks, and biofuels being considered. Biofuels, produced from biomass, are gaining traction in Australia as a cost-effective and sustainable alternative to traditional fuels. The Truck Industry Council (TIC) is advocating for the inclusion of Low Carbon Liquid Fuels (LCLFs) in the industry to meet zero-emissions targets. Manufacturers like Penske Australia, Isuzu, and Volvo Trucks Australia are supportive of biofuel integration in their truck models to reduce emissions and improve sustainability. However, the high price of biofuels remains a barrier for many truck owners. Volvo Trucks Australia has taken a significant step by using Hydro Treated Vegetable Oil (HVO) in its new truck models, demonstrating a proactive approach towards biofuel usage. While the industry shows positivity towards biofuels, challenges such as cost barriers need to be addressed for broader adoption in the Australian trucking sector.
