Utilisation of CO2 and its conversion into valuable products
Carbon dioxide is a valuable commodity for many Australian industries for which it essential to maintain a robust supply chain (e.g., food production including protective cropping and microalgae, pH control in water treatment, modified environment packaging). As these industries currently use CO2 derived from non-renewable fossil resources, they face an immediate challenge in transitioning to sustainable sources of CO2.
Why this research is valuable
Sustainable CO2 production (i.e., from the air rather than fossil resources) enables the development of a ‘circular economy’ from which valuable commodity chemicals can be produced. These processes will use renewable electricity and will open opportunities to use low-cost energy to generate the CO2, displace the use of fossil fuels and by designing the processes to operate intermittently in an efficient manner, offer a way to stabilise the electricity grids.
- Developing advanced nanomaterials (e.g., MOFs) for (i) electrochemical CO2 reduction to high value-added products through standard intermediates such as ethanol and ethylene, and (ii) green methane and methanol. We would seek to utilise green hydrogen as a reactant.
- Integrating advanced nanomaterials into units for industrial-scale conversion including plasma driven synthesis of hydrocarbons from CO2.
- Developing viable produce separation/purification methods for the value-added products.
