SMI faces down the net zero Goliath

The Sustainable Minerals Institute (SMI) based at Queensland University is gamely facing down a critical minerals conundrum in its bid to help the transition to a renewable economy. It goes like this. A 2050 deadline has been put on net zero carbon emissions and the world is looking for energy alternatives to replace fossil fuels. Existing alternatives require a far greater commitment to mining critical minerals and these require left-of-field thinking to develop processes that can extract said elements. This mining and processing will require a lot of energy. Associate Professor Steven Micklethwaite. It adds up to what Associate Professor Steven Micklethwaite says is a ‘wicked problem.’ Associate Professor Micklethwaite is the leader of the SMI’s Resourcing Decarbonisation unit. His team is tasked to develop new methods of processing more minerals with a lower carbon footprint so the rest of society can contribute the same by consuming zero-emission generated energy.

Or if we are mining them they're small volume, high grade resources that are quite distributed. And so how do you get scale of development to make it an economic enterprise? “How do we take advantage of those metals as well too in terms of not just producing the concentrate, but actually turning it into products that are useful for the transition?” Associate Professor Micklethwaite’s work draws on scores of researchers and industry partners addressing the various facets of the transition.

And what do we need to collect? What can we proxy? What in order to be able to make those calculations? “And then when you have the calculations … then you need to do the homework as to say, well, what does this mean in terms of policy or regulation?” Video and audio of the QEC Tech Summit is being uploaded.
