Navy members discussing the refuelling of renewable diesel in ADV Reliant.
Brigadier Mark Baldock, Director General Fuel Capability, said the initiative reflects Defence’s commitment to improving energy resilience and diversifying fuel supply chains. He stated: “Renewable diesel offers a practical pathway to strengthen Australia’s sovereign fuel supply, while contributing to a more sustainable Defence force. By improving our ability to operate flexibly across a range of fuel types, Defence is now better equipped to adopt cleaner and more resilient energy solutions across our operations.”
ADV Reliant is an offshore support vessel with significant range, endurance, and specialist equipment to deliver Australian Government-directed activities. Over the next two months, the vessel and her crew will visit Pacific Island nations to deliver essential supplies and equipment, supporting Australia’s ongoing commitment to regional stability and partnership.
Commodore Heath Robertson, Commander Support Force, said the vessel will also serve as a platform for education and awareness around sustainable fuels, both in Australia and across the Pacific. He commented: “The fueling of ADV Reliant with renewable diesel marks a significant step in our efforts to integrate sustainable fuel alternatives into Navy operations. This initiative will provide critical support to national emissions reduction objectives, particularly in the southwest Pacific, where the effects of climate change are already being felt.”
The Defence Department is collaborating with industry to transition to domestically produced fuel as Australia scales up low-carbon fuel production. Renewable diesel is a drop-in replacement for traditional fossil-based marine diesel fuel, compatible with both military and civilian platforms without requiring modifications to ships, equipment, or fuel handling systems.
This milestone demonstrates Australia’s ability to operate Defence platforms sustainably while maintaining operational readiness. The use of renewable diesel supports emissions reduction goals, strengthens energy security, and provides a practical pathway for adopting cleaner fuels across military operations.
By successfully integrating renewable diesel into operational use, ADV Reliant sets an example for future vessels and broader Defence initiatives. The vessel’s upcoming missions in the Pacific will highlight both the operational viability of lower-emission fuels and Australia’s commitment to sustainable energy practices in the region.
Overall, this initiative marks a significant step in combining national energy security, sustainability, and operational capability, reflecting Australia’s proactive approach to adopting low-carbon technologies across critical government operations.
