The search for sustainable aviation fuel has reached a critical juncture, and the stakes are high. How can we power our planes without depleting our planet's resources?
Enter sugarcane, the unsung hero of the aviation industry's future. When it comes to replacing fossil carbon, this crop is the sweetest deal around. But why? Let's delve into the details.
At the ARC Research Hub, we tackle the challenge of engineering plants to replace fossil carbon. Our goal is to develop a renewable aviation fuel that's economically viable and produced on a massive scale. And sugarcane is our top pick for a very good reason.
Scale is the name of the game, and sugarcane is the only crop currently produced in the massive quantities needed. Other options, like algae, might sound appealing, but they are not cost-effective without generating high-value co-products. And that's a big 'if'.
Consider canola, another contender. While it's being used for fuel in Europe, it raises food security concerns. Moreover, it's a land-intensive crop, requiring an area larger than Australia to produce enough fuel to replace jet fuel. That's a massive ask!
Here's where it gets controversial: Land use is a deal-breaker, and sugarcane shines in this aspect. It's highly productive and requires a relatively small land area, making it the most sustainable choice.
Our research focuses on enhancing plant biomass conversion efficiency. We're tinkering with the genetics of rice, sorghum, and sugarcane to boost the amount of biomass that can be converted into fuel while maintaining crop yields. Rice, being genetically more manageable, is our testbed. Successful modifications in rice will be trialed in sorghum, and eventually, we'll transfer the most promising genetic tweaks to sugarcane.
Australia, and Queensland specifically, is poised to lead this revolution. With an established sugarcane industry, robust research capabilities, and global partnerships, we can accelerate the development of sustainable aviation fuel. The domestic demand is high, and a commercially viable solution will be quickly adopted worldwide.
The ARC Research Hub's mission is clear: breed crops with high biomass conversion potential without compromising yield. It's a complex task, but sugarcane is the crop that ticks all the boxes. If we succeed, Australia will be at the forefront of this sustainable aviation revolution.
This ambitious project is funded by the Australian Research Council and supported by various industry partners, ensuring a collaborative approach to tackling this global challenge.
