Driving Decarbonisation: The Push for Sustainable Rail Transport in Australia
Key Ideas
  • ARA emphasizes the urgent need for a national strategy to decarbonize the rail industry in Australia, highlighting the necessity of policy, regulations, skills, and infrastructure support.
  • Greater utilization of rail transport can significantly reduce emissions, improve health, reduce congestion, and promote sustainability in cities and communities.
  • The rail industry in Australia aims to transition to low or zero emissions technologies by 2050, with a phased approach focusing on energy efficiencies, biofuels, renewable diesel, and future adoption of technologies like battery electric and hydrogen.
  • Research and pilot projects are underway to test new technologies, with a call for increased focus on hydrogen as a potential solution for decarbonisation within the rail sector.
The Australasian Railway Association (ARA) is set to release a report on the rail industry's efforts in decarbonisation to achieve net-zero targets. The report highlights the critical need for a shared national strategy to support the transition to low or zero emissions technologies, especially as almost half of the nation's diesel-powered rollingstock will require replacement in the next decade. While progress has been made in trials for new technologies, the commercial availability of low emissions rollingstock remains a challenge in Australia. The immediate benefits of using rail transport include substantial emissions reductions and improved health and safety in cities. However, to meet long-term decarbonisation goals, the rail industry must address emissions from traction energy used for locomotives. Transitioning passenger operations to renewable energy sources is underway, while decarbonising rail freight, primarily powered by diesel, poses a more significant challenge. The industry is exploring various solutions such as biofuels and renewable diesel in the short term, with a shift towards battery electric and hydrogen technologies expected beyond 2030. Research and pilot projects on battery electric locomotives are progressing, but there is a clear need to focus more on hydrogen as a potential long-term sustainable solution. ARA advocates for increased collaboration, research, and innovation within the industry to unlock investments in low and zero emissions technologies. The organization supports information sharing through working groups and emphasizes the importance of early planning to facilitate the adoption of new technologies. As the rail sector in Australia navigates its decarbonisation journey, a concerted effort towards sustainable practices and technology adoption is crucial for a greener future.
