Turning red clay into white gold for Queensland’s economic future
Queensland has an opportunity to value-add along its battery materials (Li-ion) supply chain and other strong industries to ensure economic stability post-COVID but it will require a coordinated approach according to a QUT expert.
Associate Professor Sara Couperthwaite, a QUT researcher focused on commercial outcomes, addressed Queensland Parliamentarians on supporting job creation post-COVID at the Queensland Future Conversations breakfast this morning.
“If we make and sell products from our natural resources rather than sell these raw, we can build our capacity and ability to meet global market demands and ensure our economic future,” Associate Professor Couperthwaite said.
“Australia, and Queensland specifically, has resources and processing capabilities in the Li-ion battery value chain, and the proposed $2B Li-ion battery Gigafactory in Townsville would build our advanced manufacturing capacity.”
The Li-ion battery market was valued at $36.7B in 2019 and is projected to reach $129B by 2027—growing rapidly due to global electric vehicle targets.
The Future Battery Industries Cooperative Research Centre’s State of Play notes Australia’s many opportunities to build a battery value chain but it requires a coordinated approach by state and federal governments towards the minerals industries, downstream production and battery manufacturing.
In 2018, QUT partnered with start-up Lava Blue to develop a process that turned $70/t kaolin clay into $39,000/t high purity alumina (HPA) – a key material used in sapphire glass and battery separators.
In collaboration with the IMCRC, the research is de-risking the scale up process to a commercial plant, intended for Charter Towers, by incorporating real-time monitoring and machine learning approaches.
“This high-level of industry engagement resulted in research that could build resilience within the sector, and also provided Lava Blue with the opportunity to license technology,” Associate Professor Couperthwaite said.
