The Australian Defence Force announced Aug. 25 that it has begun rolling out low-carbon liquid-fuel (LCLF) blends across its network in an effort to strengthen fuel resilience.
The initiative introduces aviation and diesel fuels containing synthetic components to fuel installations nationwide and aligns with the 2026 National Defence Strategy to enhance energy security and operational readiness.
According to Director General Fuel Capability Brigadier Mark Baldock, diversifying fuel sources is essential to enhancing ADF’s energy security.
“Supporting domestic renewable fuel production strengthens Australia’s sovereign capability,” Baldock said. “These demonstrations are an important step toward building a more resilient and sustainable energy future for [ADF].”
Policy adviser from the Defence Energy Transition Office, Commander Steve Cole, said it was inevitable that ADF would start to use LCLF.
“Australia is increasingly looking to be self-sufficient, so the focus at DETO is making sure that [ADF] is prepared to use these fuels as they become available,” Cole said.
LCLFs are made from a source other than crude oil—be it canola oil, sugarcane, waste oils or forestry residue.
They are chemically indistinguishable from fossil fuels, allowing them to be used without modifications to ADF equipment.
DETO has undertaken certification processes and platform demonstrations of renewable diesel and sustainable aviation fuel (SAF), including during Exercise Talisman Sabre and the Avalon Air Show.
“A big part of these demonstrations has been taking maintainers and crews of the platforms, planners and decision-makers on a journey to understand we are talking about drop-in replacement fuels that meet the same specifications,” Cole said.
Since then, DETO has focused on adopting certification for ADF platforms to ensure internal assurance processes are met and to facilitate interoperability with partner nations that are also adopting LCLFs.
All ADF aviation and land assets are now certified to operate on LCLF, with the Royal Australian Air Force Base East Sale and the Army Aviation Training Centre already using blended fuel.
Certification of remaining maritime platforms is nearing completion.
ADF has established the Defence Fuels Qualification Centre in partnership with the Defence Science and Technology Group.
The center will promote fuel standards awareness, conduct qualification testing and strengthen collaboration with industry to enable sovereign fuel production.
