Description

Enhancing magnesium mineral carbonation for sustainable carbon storage. Subsurface carbon mineralisation enables long-term storage of anthropogenic CO2 emissions. This project aims to quantify the effect of water composition (ionic and pH) on the efficiency of magnesium-based carbon mineralisation, and hence exploit a unique Australian combination of natural acidic brine and mafic mine tailings (both waste streams) to continuously produce optimal carbonate products enabling economic carbon capture. Critical is mineralisation that maximises carbon capture whilst retaining high system gas and liquid permeability. To this end, magnetic resonance techniques using ferromagnetic contrast will be developed to non-invasively monitor the onset of this mineralisation and the subsequent pore space modification. .
