Green Hydrogen for Road Transport in Western Australia

Australia’s commitment to net zero emissions by 2050 puts the transport sector in sharp focus, as it generates more than one-fifth of the nation’s emissions. Many mining sites are located far from ports and processing hubs, and the fragmented rail network limits the use of freight rail, making road transport essential. Road transport accounts for more than 85% of transport emissions, with trucks and buses responsible for around 30%. Australian freight is characterised by heavy payloads and long distances, often along remote routes far from the high-voltage grid.

Battery-electric trucks (BETs) and hydrogen fuel-cell trucks (FCTs) both present viable pathways to zero emissions. While BETs are more energy efficient, FCTs excel in scenarios demanding high payload capacity, fast refuelling and independence from the grid, which are key factors in Australian freight. Current government projections indicate that fossil fuels will still supply 40% of road transport energy by 2050, but in the full decarbonisation scenario, zero emissions can be achieved if hydrogen complements electrification.
