Biofuels in Australia: The Overlooked Alternative to Imported Fuel

As I have written previously, one topic often leads you to another, talking on AI, EV’s and infrastructure with an audience, tends to bring up the topic of energy and fuel.

Much of the discussion around energy in Australia focuses on electricity, renewables, and electrification.

But there is another part of the energy system that remains heavily dependent on imports.

Liquid fuels.

Transport, aviation, mining, agriculture, and heavy industry still rely overwhelmingly on diesel, petrol, and jet fuel, much of it sourced from overseas.

This raises a strategic question:

Are imported fossil fuels the only option?

The answer is no.

Australia already has the resources to produce a significant portion of its own liquid fuels through biofuels.

Australia’s Biofuel Opportunity

Biofuels are produced from biological materials:

  • crops (sugarcane, grains, oilseeds)

  • agricultural residues

  • waste oils and fats

  • forestry by products

 Unlike fossil fuels, these are renewable and domestically available.

Australia is uniquely positioned due to:

  • large agricultural output

  • strong export capacity (e.g. canola and sugar)

  • significant biomass waste streams

 Research from the CSIRO and Australian Renewable Energy Agency indicates that bioenergy could supply a meaningful share of Australia’s future energy demand, particularly in sectors that are difficult to electrify.

Ethanol from Sugarcane and Grains

Ethanol is the most widely used biofuel globally.

In Australia, it is produced from:

  • sugarcane (via molasses)

  • wheat and sorghum

 Ethanol production involves fermenting sugars into alcohol, which can then be blended with petrol.

 Current Use

  • Common blend: E10 (10% ethanol)

  • Compatible with many modern vehicles (checking with manufacturer required before using)

  • Supported by existing fuel infrastructure

 Australia has multiple ethanol production facilities, particularly in Queensland and New South Wales, with capacity in the hundreds of millions of litres annually.

Sugarcane: A Dual Energy Resource

Sugarcane offers a significant advantage as a biofuel feedstock.

It produces:

  • ethanol

  • electricity (from bagasse, the fibrous residue)

Bagasse is already used to generate renewable electricity in Australia, contributing to regional energy systems.

 There is also increasing focus on:

  • sustainable aviation fuel from sugarcane waste

  • advanced biofuels derived from agricultural residues

Biodiesel from Canola and Waste Oils

Biodiesel is produced from:

  • canola oil

  • animal fats (tallow)

  • used cooking oil

 It has the potential to be used in existing diesel engines, with minimal modification.

The Canola Opportunity

Australia exports millions of tonnes of canola annually, much of it processed overseas into biofuels.

This presents a clear opportunity:

Instead of exporting feedstock, Australia could produce fuel domestically.

This would support:

  • local fuel production

  • regional industries

  • reduced reliance on imports

Beyond Crops: Waste and Advanced Biofuels

The next phase of biofuel development focuses on non-food feedstocks.

These include:

  • agricultural residues

  • forestry by products

  • municipal waste

  • algae based systems

 Australia produces significant volumes of biomass waste annually, much of which remains underutilised.

Emerging technologies are enabling conversion of these materials into:

  • biofuels

  • synthetic fuels

  • bioenergy products

 This expands the potential resource base beyond traditional crops.

Energy Security and Infrastructure

Biofuels are not just about emissions.

They are about energy security.

 Australia:

  • imports a large proportion of its liquid fuels

  • relies on global supply chains

  • has limited domestic refining capacity

 Domestic biofuel production offers:

  • improved supply resilience

  • reduced exposure to global disruptions

  • integration with existing fuel infrastructure

 Importantly, biofuels can often be:

  • blended into current fuels

  • transported using existing systems

  • used in current engines

 This makes them one of the few scalable alternatives for liquid fuel systems.

The Economic Reality: Fuel Prices and Supply Risk

Global fuel markets have become increasingly volatile.

Australia, as a net importer of refined fuels, is directly exposed to:

  • global oil price fluctuations

  • geopolitical disruptions

  • refining capacity constraints

  • currency movements

Data from the Australian Competition and Consumer Commission and global analysis from the International Energy Agency show that fuel prices have experienced sustained volatility in recent years.

These fluctuations directly impact:

  • transport costs

  • agricultural production

  • logistics and supply chains

  • cost of living

 At the same time, long term global trends suggest continued pressure on liquid fuel markets due to:

  • demand growth

  • supply constraints

  • energy transition impacts on refining

 This creates a structural challenge.

Australia relies on imported fuels for critical sectors, and yet, it has limited control over price or supply.

Why Timing Matters

Rising fuel costs and supply uncertainty change the economics of alternatives.

Biofuels, which may previously have been considered marginal, become more viable when:

  • fossil fuel prices increase

  • supply chains are disrupted

  • energy security becomes a priority

 This is not just an environmental issue.

It is an infrastructure and economic resilience issue.

Historically, periods of fuel price volatility have accelerated:

  • investment in alternative fuels

  • domestic production capability

  • diversification of supply

 For Australia, this presents an inflection point.

Where Biofuels Fit

Biofuels are unlikely to replace all fossil fuels.

But they are well suited to sectors where electrification is difficult:

  • aviation

  • heavy transport

  • mining

  • agriculture

  • shipping

These sectors are critical to Australia’s economy.

The Strategic Opportunity

Australia already has:

  • the feedstock

  • the land

  • the engineering capability

  • the infrastructure base

 What is missing is scale.

The opportunity is not just to produce biofuels.

It is to build an integrated domestic fuel system.

Closing Thought

The transition to new energy systems is often framed as a shift to electricity.

But liquid fuels remain essential.

Biofuels offer a pathway to:

  • reduce emissions

  • improve energy security

  • leverage existing infrastructure

 And importantly:

They demonstrate that imported fossil fuels are not the only answer.

The question is no longer whether alternatives exist, but whether Australia chooses to develop them while the conditions make it viable.
