Next season, the roar of Formula 1’s V6 turbocharged engines will be accompanied by a quieter revolution: all teams on the grid will run on 100 percent sustainable fuels. Gone are the days when F1 cars relied solely on petroleum-derived gasoline; instead, five specialist suppliers will provide drop-in blends of synthetic and biofuels that recycle carbon dioxide and cut lifecycle greenhouse-gas emissions by up to 80 percent. Formula 1’s chief communications officer, Liam Parker, says the move “demonstrates how existing internal-combustion engines can deliver top performance while helping the wider automotive sector transition to net zero.”
Fuel Innovation Filters Down to Road Cars
Sustainable fuels in F1 promise zero loss of power or top speed—cars will still hit 330 km/h on straights—yet the technology is fully compatible with today’s engines and fuel infrastructure. Parker notes that “fans will witness green racing in real time, and consumers could soon fill their personal vehicles with the same low-carbon blends.” By using existing pipelines, bowsers and refineries, these drop-in fuels avoid the costly, decade-long rollout of new infrastructure required for hydrogen or electric charging networks, offering a rapid pathway to slashing emissions.
Synthetic vs. Bio: Two Paths to Lower-Carbon Liquids
Australia’s fledgling low-carbon liquid fuel industry divides into two main streams:
Biofuels are produced from organic waste—used cooking oil, sugarcane residues, sawmill offcuts—and have matured over decades. They literally breathe in carbon as crops grow, and return it when burned, closing the loop.
Synthetic fuels (e-fuels) are created atom by atom. Renewable energy splits water into hydrogen, and carbon is captured either from the atmosphere or sustainable industrial sources. These building blocks recombine via Fischer-Tropsch or other processes into hydrocarbons chemically identical to gasoline, diesel or jet fuel—but with near-net-zero CO₂.
CEFC Executive Director Rupert Maloney predicts that by 2050, Australia’s low-carbon liquid fuel market could swell to A$36 billion annually, alongside a A$15 billion feedstock industry. “These fuels bridge today’s fleets to the net-zero era,” he says.
Australia’s Edge: Feedstocks, Renewables and Export Potential
Two global consortia have singled out Australia for its abundant renewables and feedstocks:
HIF (Highly Innovative Fuels) plans a A$2 billion plant in Tasmania, scaling up from a Chile pilot to produce 100 million L of e-fuel per year by 2030—enough to power a quarter of Tasmania’s transport energy needs. Porsche is among its investors. CEO Ignacio Hernandez cites Australia’s “world-class wind and solar potential” as pivotal for driving down hydrogen costs.
Zero Petroleum, co-founded by ex-F1 engineer Paddy Lowe, eyes South Australia for a 10 million-L facility targeting aviation bio-jet, gasoline and diesel. Its team is assessing local carbon sources—CO₂ from fermentation plants or direct-air capture—to feed its modular synthesis units.
Beyond production, Australia imports 80 percent of refined transport fuels via complex supply chains vulnerable to geopolitical shocks. CSIRO’s Minerals Resources Lead Max Temminghoff argues that domestic e-fuel manufacturing would strengthen fuel security while localizing economic value.
Qantas’s High-Altitude Test Flight
Sustainable aviation fuel (SAF) adoption is the vanguard of low-carbon liquids in transport. In May, Qantas imported 1.7 million L of bio-jet from Malaysia to blend at 18 percent with conventional kerosene—enough for 900 Sydney–Auckland return flights, cutting 3,400 tonnes of CO₂. Chief Executive Vanessa Hudson calls for “a domestic SAF industry” to avoid reliance on overseas supply and scale up blending mandates.
Cost Hurdles and Policy Levers
Today, e-fuels cost two to three times conventional fossil fuels, reflecting expensive electrolytic hydrogen and nascent CO₂-capture technology. But industry leaders foresee rapid cost declines under the right policy environment:
Renewable-energy price reductions—as wind and solar farms proliferate, power costs fall, making hydrogen production cheaper.
CO₂-capture innovation—advances in direct-air capture or utilisation of waste-stream CO₂ will cut feedstock costs and environmental impact.
Blending mandates—Asia’s 1 percent biofuel blend obligations send market signals; Australia’s federal government in March pledged A$250 million in grants but has yet to legislate national blending targets. A modest mandate would guarantee demand, spur investment and drive economies of scale.
“The missing piece is regulation that requires sectors—especially aviation, heavy transport and mining—to blend or switch,” Maloney stresses. “Mandates of just 1–2 percent can unlock billions in private capital.”

Electrification vs. Liquid Fuels: A Complementary Approach
While passenger EV sales in Australia reached only 1 percent of the 15.7 million-strong fleet (159,000 vehicles) by early 2024, the road ahead looks electrified. However, low-carbon liquids fill critical gaps:
Heavy goods transport—trucks and buses rack up hundreds of kilometres daily under weight and range constraints that battery-electric designs struggle to meet.
Shipping and aviation—long-haul vessels and jetliners cannot yet rely on batteries alone; SAF and marine biofuels offer immediate CO₂ reductions.
Remote mining and agriculture—off-grid operations depend on liquid-fuel generators where renewables may lack reliability.
Hernandez of HIF argues that “drop-in” e-fuels complement the EV transition, ensuring existing fleets and hard-to-abate sectors decarbonize swiftly.
International Momentum, Domestic Opportunity
Europe and Asia have enacted SAF and biofuel mandates—Germany aims for 25 percent aviation fuel by 2030; Japan targets 10 percent for all road diesel by 2030. Australia’s lagging policy puts it at risk of exporting raw e-fuel rather than capturing domestic value. However, federal grants and state incentives in Queensland and Western Australia signal growing political will.
Minister for Climate Change Chris Bowen declared: “Australia has the know-how to decarbonize transport sectors that rely on liquid fuels.” But industry calls for clearer legislation: blending rates, tax credits, and carbon pricing will determine whether local plants thrive or shipments head overseas.
Fast Lane to Net Zero
As F1 cars blast around circuits on sustainable fuel in 2026, they will embody the promise of low-carbon liquids clear to everyday motorists and policymakers. Australia, blessed with sun, wind and industrial feedstocks, sits on the brink of a multi-billion-dollar e-fuel economy—but only if regulators green-light the track ahead. In the meantime, Qantas flights and racing engines will jockey for position, showcasing what’s possible when innovation meets ambition: carbon-neutral combustion, ready to fill bowsers from Melbourne to Monaco.
