Can Algae Biofuels Fix Australia's Diesel and Aviation Fuel Security?

Australia imports nearly 80% of its liquid fuels, leaving the economy vulnerable to global supply shocks. While traditional biofuels often compete with food crops for land, microalgae offer a high-yield alternative that can grow on non-arable land and utilize wastewater. Recent advances in bioreactors and hydrothermal liquefaction make algal diesel and sustainable aviation fuel more viable. By leveraging abundant sunlight and non-arable land, Australia could reduce its reliance on imported crude oil and lower transport emissions.
