One of the coolest ways I get to support my sector of science, technology, and innovation is to help assist those events that celebrate the pioneers and exemplars of our field - and they don’t get any bigger than the night of nights for Australian innovators and technologists with the incredible Australian Academy of Technological Sciences & Engineering's ATSE Awards 2024. So it was truly wonderful to be allowed to host the evening (and also see honoured colleagues I have been privileged also to call my friend for over a decade!)

The transition to green steel production is pivotal for reducing global carbon emissions. My student Matthew Humbert undertook this study on a comprehensive techno-economic analysis of various green steel production methods, including hydrogen reduction and three different electrolysis techniques: aqueous hydroxide electrolysis (AHE), molten salt electrolysis, and molten oxide electrolysis (MOE).
The analysis reveals that MOE, despite its ongoing development, offers a promising route for iron production given its ability to process a wide range of ore qualities and the potential to sell electrolyte as a cement product. However, the best balance between deployment ready technology and economic benefit is AHE.
