Confirmation seminar presented by Muhannad Al Kalbani.

In-situ CO2 mineralisation – often referred to as mineral carbonation – is a process of permanently converting carbon dioxide into stable carbonate minerals such as calcite, dolomite, magnesite, and siderite. This is typically performed by injecting CO2 underground to undergo an exothermic reaction with the host rock to form carbonate minerals. This process can remove large amounts of CO2 from the atmosphere and permanently store it underground. The urgent need to accelerate permanent anthropogenic CO2 abatement has led to a growing interest in in-situ CO2 mineralisation globally. This study focuses on the thermo-mechanical effects of CO2 mineralisation on dunite, serpentinite, and basalt samples under in-situ stress using true triaxial stress apparatus. It also addresses the sustainability of continuous in-situ CO2 mineralisation as permeability changes with the changing minerology. It also attempts to answer several key questions related to in-situ CO2 mineralisation in ultramafic and mafic rock formations. Some of these cover investigating the limiting factors to CO2 mineralisation in target rocks, while exploring potential methods to overcome these limitations. Additionally, investigating the extent of secondary fractures created from CO2 injections and the role they play in sustainable injection.

About Confirmation Seminars

The purpose of the confirmation milestone is to ensure that the candidate receives appropriate feedback in relation to the viability and progress of the thesis project and that the resources required to complete the program of research within the recommended timeframe are available. It is also an opportunity to ensure that the candidate has demonstrated the capacity and capability to successfully complete the thesis in a timely manner.
