Model studies of Australian lump ore applied to blast furnace ironmaking. Ore lump use in ironmaking blast furnaces (BFs) requires no preprocessing and has a lower carbon footprint. However, it suffers various technical problems. This project aims to understand and optimize the conditions for such operations. This will be achieved by means of a combined theoretical and experimental program, involving the use of state-of-the-art multiscale computer modelling and simulation techniques.

However, it suffers various technical problems. This project aims to understand and optimize the conditions for such operations. This will be achieved by means of a combined theoretical and experimental program, involving the use of state-of-the-art multiscale computer modelling and simulation techniques. The research outcomes will be tested in the design and control of lump charging operations in practice through collaboration with the industrial partner. This will ultimately increase Australian ore lump usage in BFs, leading to significant financial and environmental benefits to Australia and the entire steel industry worldwide.Read moreRead less
Carbon-neutral copper: unlocking metal value through carbon sequestration. This project aims to explore how the concepts of reaction-induced porosity and coupled dissolution-reprecipitation reactions, which have had a profound impact in geosciences, can be exploited in the context of ore processing through carbon sequestration. The project's main outcomes are to generate a new process that maintains porosity in ore, and a combination of lixiviants, for effective Cu metal recovery and Fe capture. ....Carbon-neutral copper: unlocking metal value through carbon sequestration. This project aims to explore how the concepts of reaction-induced porosity and coupled dissolution-reprecipitation reactions, which have had a profound impact in geosciences, can be exploited in the context of ore processing through carbon sequestration. The project's main outcomes are to generate a new process that maintains porosity in ore, and a combination of lixiviants, for effective Cu metal recovery and Fe capture. This project will benefit the mineral industry by providing an alternative to the current paradigm in Copper mineral processing that requires the destruction of the mineral hosting economic value, thereby developing sustainable mining technologies well suited for the increasingly complex ores being extracted in Australia.

Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and product ....Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and production of a phosphorus rich co-product for agriculture. Benefits are anticipated to include increased utilisation of steel slag, creation of a valuable fertiliser co-product, decreased greenhouse gas emissions, and a reduction in the penalty applied to Australian iron ores.Read moreRead less
High Performance Anode for Direct Ammonia Solid Oxide Fuel Cells. Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen. For direct ammonia solid oxide fuel cells, the key ....High Performance Anode for Direct Ammonia Solid Oxide Fuel Cells. Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen. For direct ammonia solid oxide fuel cells, the key challenge is the anode. This project aims to develop a high performance anode for direct ammonia solid oxide fuel cells with both high activity and high stability at low temperature (below 600 degree C), thus addressing a key issue to make the direct ammonia solid oxide fuel cells commercially viable.Read moreRead less
Composites for thermal expansion matched oxygen electrodes. This project aims to develop high performance composite oxygen electrodes by using both negative thermal expansion materials and electrolyte materials to tailor the thermal expansion and activities of the perovskite-based electrodes for use in reduced temperature solid oxide cells. Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing high activity at reduced temperatures.

Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing high activity at reduced temperatures. This project seeks to address an important practical issue in the operation of solid oxide power cells - thermal expansion compatibility, which causes poor efficiency outside a narrow temperature band.Read moreRead less
Improved hydrogen geological storage via zeta potential measurements. Hydrogen is a clean fuel which has the potential to revolutionize the energy supply chain by complete decarbonisation. An estimated 50-fold increase in the global hydrogen market is expected by 2050, totalling AUD$16.3 trillion. However, the key barrier to a hydrogen economy is hydrogen storage, as hydrogen is highly volatile, compressible and flammable. Underground hydrogen storage, i.e. storage of hydrogen in sedimentary geo ....Improved hydrogen geological storage via zeta potential measurements. Hydrogen is a clean fuel which has the potential to revolutionize the energy supply chain by complete decarbonisation. An estimated 50-fold increase in the global hydrogen market is expected by 2050, totalling AUD$16.3 trillion. However, the key barrier to a hydrogen economy is hydrogen storage, as hydrogen is highly volatile, compressible and flammable. Underground hydrogen storage, i.e. storage of hydrogen in sedimentary geologic formations, is a potential option to solve this problem. In this project we will provide fundamental data required to establish hydrogen underground monitoring techniques, and to develop associated large-scale models with which underground hydrogen storage efficiency and security can be predicted.Read moreRead less

Globally, over 1 billion tonnes of iron are produced each year consuming 30 billion billion (Quintillion) Joules energy! and creating over 300 million tonnes of molten oxides (slags). Our industry partners need new advanced thermodynamic databases and computer models with which to optimise their major industrial processes and develop new technologies. By delivering these tools, this project expects to benefit both industry and the community through improved process efficiencies, and reductions in energy usage, pollutants, and environmental impacts.

This project aims to test effective strategies to re-use Australia’s depleted gas fields for large-scale, long-term, renewable energy storage. With Australia’s energy system undergoing a radical hydrogen-based energy transformation, a critical challenge in the years ahead will be to effectively store massive volumes of hydrogen for long periods (months and years). The overall expected outcome of this research is to fully understand the performance and the geological and environmental implications of long-term storage of hydrogen in empty gas fields. Benefit: this foundational scientific knowledge is crucial if Australia is to effectively bring about this new, sustainable, affordable, long-term, hydrogen-storage solution. Read moreRead less
