Carbon sequestration using Carbon dioxide in water nano-emulsions

This Earmarked Scholarship project is aligned with a recently awarded Category 1 research grant. It offers you the opportunity to work with leading researchers and contribute to large projects of national significance.

Supervisor –Dr Mahshid

Carbon Capture and Storage (CCS) has recently gained significant attention for reducing greenhouse gas and to address the climate issue.  In conventional CCS, CO2 is generally stored as a pure supercritical fluid, which rises up in the formation until a geological seal layer is reached; this seal provides a structural trap preventing the escape of the fluid out of the subsurface. A restricting concern and risk is the reliability of this seal which can have sand sections or faults which might allow the buoyant CO2 to escape to overlying aquifers, even over centuries. This project aims to develop a novel and reliable method for permanent CCS, in which CO2 is injected as a nano-emulsion in water in order to increase the CO2 solubility and thereby accelerate its reaction with rocks. This project will more specifically investigate the formation of a stable nano-emulsion of CO2 in water using environmentally benign surfactants and demosntrate the mineralisation of the CO2 into stable carbonate solids by analysing the reaction rates and products.

The successful applicant will be working in a group of academics from different disciplines from School of Chemical Engineering and School of Earth and Environmental Sciences.

Preferred educational background

Applications will be judged on a competitive basis taking into account the applicant's previous academic record, publication record, honours and awards, and employment history.

A working knowledge of emulsions /foams which include characterisation and mathematical modelling of the emulsion would be of benefit to someone working on this project.

The applicant will demonstrate academic achievement in the field(s) of chemical engineering, physical chemistry, carbon capture and storage and the potential for scholastic success.

A background or knowledge of reaction and mineralisation of CO2 and CMG simulation is highly desirable.

*The successful candidate must commence by Research Quarter 2, 2022. You should apply at least 3 months prior to the research quarter commencement date. International applicants may need to apply much earlier for visa reasons.
