PhD candidates from the University of Adelaide:

  • Mohammad Rezaee (MR), 

  • Mostafa Montazeri (MM),

  • Kofi Ohemeng Kyei Prempeh (KO) 

(MR) This project develops a two-stage leaching and carbonation pathway that converts iron-rich tailings into stable carbonates while storing CO2. Using bio-derived acetic chemistry under mild, scalable conditions, hematite is dissolved to generate Fe2+, which is subsequently mineralized as siderite (FeCO3) at near-ambient temperature and pH. The approach integrates green dissolution with controlled carbonate formation in a compact aqueous loop, amenable to scale-up. Sustainability benefits arise from low-hazard inputs, modest energy demand, and circular use of tailings coupled to permanent CO2 fixation. The resulting usability of siderite as an aggregate in concrete production and its effects on the physical properties of the concrete mixture will be evaluated.

(MM) The high production cost of renewable-electrolyser hydrogen makes precise design of underground hydrogen storage (UHS) systems essential. This study develops an integrated modelling framework that identifies critical surface equipment, determines their optimal sizes, estimates energy consumption, and calculates the levelized cost of storage (LCOS). A comparative case study between the proposed and a non-optimized benchmark verifies the model’s reliability, demonstrating significant reductions in energy requirements and in the number of costly surface units such as compressors. The framework provides a robust decision-support tool for techno-economic optimization of large-scale UHS projects.

(KO) Carbon dioxide (CO₂) storage in deep geological aquifers is a leading strategy for climate change mitigation. The accurate modelling of CO₂ injection is critical for evaluating storage performance and ensuring long-term reservoir integrity, particularly under conditions of high geological uncertainty. While conventional numerical simulators are widely used, their high computational cost limits their practicality in large-scale studies and sensitivity analyses. This study develops an analytical upscaling framework for CO₂-brine displacement in heterogeneous porous media, incorporating spatially dependent fractional flow. The model provides exact implicit expressions for front propagation, mixture zone evolution, and phase flux trajectories, enabling rapid assessment of injectivity and sweep efficiency. The framework offers a fast, robust tool for screening and optimizing CO₂ storage projects under diverse geological conditions. 

Mohammad Rezaee is a PhD candidate in Chemical Engineering at The University of Adelaide, dedicated to developing sustainable solutions for carbon capture, utilization and storage (CCUS) through mineral carbonation of mine tailings and industrial wastes. Mohammad has a background in Reservoir engineering and previously worked in the semiconductor industry. He relocated to Australia to pursue a PhD and transition into the energy sector.

Mostafa Montazeri is a second-year PhD candidate in Petroleum Engineering at the School of Chemical Engineering, University of Adelaide. He holds an M.Sc. in Chemical Engineering (Separation Processes) and a B.Sc. in Chemical Engineering (Refinery, Petrochemical, and Gas). He has two years of Drilling-field experience and five years at the Research Institute of Petroleum Industry (RIPI)-Iran as a researcher and project leader. His research focuses on Comprehensive modelling of surface infrastructure and reservoir flow for Underground Hydrogen Storage, combining experimental and computational approaches.

Kofi Ohemeng Kyei Prempeh is in the final year of his PhD in Petroleum and Reservoir Engineering at the University of Adelaide, where he researches carbon dioxide storage in heterogeneous porous media. He has a background in Petroleum Engineering and Applied Mathematics and previously worked as a Lecturer and Research Associate in Ghana. Kofi moved to Australia to pursue his doctoral studies and explore opportunities in the energy sector.
