Why Renewable Fuels Are Critical to Decarbonising Australia's Liquid Fuel Sector

There is a growing consensus across industry and government that Australia must build a domestic renewable fuels industry, and that the window to act is now. Bioderived renewable fuels can decarbonise the sectors that are hardest to electrify, and a clear set of policy levers is available to governments to make that transition happen. For a company like MorFuels, this national conversation aligns closely with the business we are building.

Why Liquid Fuels Still Matter

Liquid fuels are not a fringe part of the economy. They account for a large share of Australia's total energy used by industry, households and government, and demand has grown steadily for two decades. Transport, mining, construction and agriculture all depend on liquid fuels, and most cannot be electrified quickly or cheaply. This is exactly why renewable fuels matter. They can be used as drop-in replacements within existing engines and infrastructure, delivering immediate emissions cuts without waiting for fleets to be replaced.

A Global Emissions Challenge

The scale of the problem is enormous. Liquid fuels are responsible for billions of tonnes of carbon dioxide equivalent emissions globally each year, yet renewable fuels still make up only a small fraction of global liquid fuel demand. There is vast room to grow. Renewable fuels offer both a short-term decarbonisation pathway and a long-term solution for aviation and heavy transport, while complementing hydrogen and electrification rather than competing with them.

The Risk of Inaction

The consequences of inaction are significant. Without adequate government support, a domestic renewable fuels industry may simply fail to materialise. Australia's high-quality feedstocks could be exported to countries with stronger incentives, such as the United States, so that the value is captured overseas. Continued reliance on imported liquid fuels leaves the nation exposed to supply shocks and price spikes. The economic upside is substantial too. Australia's publicly released Bioenergy Roadmap, prepared for ARENA, estimates that a mature bioenergy sector could add up to 10 billion dollars to GDP each year and create around 26,200 new jobs by the 2030s.

The World Is Already Moving

While Australia has limited direct federal policy for renewable fuels, other regions are moving fast. Brazil's RenovaBio program sets compulsory decarbonisation targets for fuel distributors. The United States Inflation Reduction Act provides a sweeping array of tax credits and support measures. The European Union's Renewable Energy Directive targets a 45 percent cut in emissions by 2030 and a 14 percent renewable share in transport. Each of these frameworks is drawing investment and feedstock toward those markets, underlining the urgency for Australia to compete.

What Even Modest Adoption Could Achieve

Consider a realistic scenario in which Australia adopts modest blending policies similar to those already seen in New South Wales: replacing a small share of petrol with bioethanol, a portion of diesel with biodiesel, and a growing share of jet fuel with sustainable aviation fuel. Even modest blends deliver striking results. Replacing a few percent of petrol demand can be the equivalent of taking hundreds of thousands of passenger vehicles off the road each year, while blending sustainable aviation fuel into jet fuel, in line with targets already set by carriers such as Qantas, can meaningfully cut aviation emissions. Small percentages applied across a nation's fuel supply add up quickly.

The Barriers to Overcome

The challenges are real. Producing renewable fuels currently costs more than fossil fuels for most pathways, and price-sensitive consumers limit uptake. Some infrastructure and fleets have limits on how much blended fuel they can use without upgrades. Feedstocks are often dispersed, requiring new supply chains, and some fossil fuels still receive subsidies that distort the market. None of these barriers are insurmountable, but overcoming them requires a coordinated approach and, above all, supportive policy.

The Policy Levers That Work

A handful of policy levers are widely recognised as the most effective for building a renewable fuels industry. Taxation treatment is foundational, including fuel excise support and tax credits for producers, blenders and users based on avoided emissions. Fuel carbon intensity standards are a powerful complement, setting a renewable fuel target backed by a tradable crediting system. Capital grants and incentives reduce the upfront cost and risk of new projects, while concessional loans and contracts for difference help close the financing gap. An integrated response that combines all of these would be most effective at unlocking investment.

A Pathway to 2050

Renewable fuels are best understood as a solution across short, medium and long-term horizons. Bioethanol and biodiesel can bridge passenger vehicles toward electrification, while biodiesel and renewable diesel serve as long-term solutions for mining, construction, agriculture, maritime and rail. For aviation, sustainable aviation fuel is the primary long-term answer. This staged pathway to 2050 shows renewable fuels working alongside electrification and hydrogen, not against them.

What This Means for MorFuels

The MorFuels model answers many of these challenges directly. By growing Moringa oleifera on Australian soil, including rehabilitated mining land, MorFuels secures a domestic feedstock rather than exporting it. By producing both biodiesel and sustainable aviation fuel through the proven HEFA pathway, it targets exactly the sectors that are hardest to electrify. And through its whole-plant, negative cost fuel model, MorFuels helps address the commercial readiness barrier that holds so many projects back. As Australian policy continues to evolve toward an integrated national response, MorFuels is positioned to be part of the solution the country needs.
