Hydrogen Trains (HTs) are gaining attention in Australia as a solution to decarbonise rail transport and replace diesel locomotives with cleaner alternatives. By using hydrogen as a fuel, HTs produce only water and heat as by-products, leading to minimal environmental impact. However, challenges exist in implementing HTs across Australia's vast rail network. While HTs may not be suitable for urban areas due to competition from battery-electric trains with existing charging infrastructure, they show promise for remote regions that require trains to travel long distances without refuelling. The complexity and cost of HT infrastructure, such as refuelling stations, pose challenges, especially in remote areas. Despite these obstacles, the Australian government is investing significantly in the hydrogen industry through programs like the Hydrogen Headstart Program and tax incentives to support HT adoption and infrastructure development. By capitalizing on these investments, proponents of HTs aim to scale up usage across Australia and remote regions, reshaping the rail transport industry.
