Why rail networks need smarter energy systems
Rail network infrastructure is a significant energy consumer, traditionally powered by diesel engines or electricity supplied through overhead lines or third rails. The transport sector is responsible for nearly a quarter of energy-related CO₂ emissions globally (IEA, 2023). Both freight and passenger demands are rising, and rail systems must adopt smarter, cleaner energy approaches to remain sustainable, reliable, and cost-competitive.
What is smart rail energy infrastructure?
Smart energy infrastructure in rail refers to the integration of advanced technologies—such as green hydrogen fuel, digital controls, and energy storage—into rail systems. These modernizations enable rail networks to transition away from fossil fuels, optimize power management, and adapt flexibly to changing operational needs. This approach supports the decarbonization of the transport sector and lays the groundwork for a sustainable future.
Benefits: efficiency, reliability, and sustainability
The adoption of green hydrogen and advanced digital systems in rail delivers optimized energy use, lower operating costs, and reliable power supply. This approach significantly reduces emissions, supports climate goals, and enhances environmental stewardship. Modelled hydrogen delivery costs via ammonia (AUS $4.10–$4.50/kg by 2030) are competitive with diesel, with further cost reductions anticipated as technology advances.
