Many biofuels haven’t panned out. Could algae make the clean diesel and aviation fuel Australia needs?

The Conversation · · 855 words · By Alexandra Thomson; Martin Lloyd; Peter Ralph
National Fuel Security Economic Competitiveness of Biofuels Sustainable Energy Alternatives

The authors, who are algae researchers, argue that Australia should invest in microalgae-based biofuels to enhance national fuel security and reduce dependence on imports. They compare the land-use efficiency and environmental benefits of algae against traditional crop-based biofuels and suggest implementing pilot projects.
