Event Description

Full Description:
Abstract: CO2 Capture, Utilization and Storage (CCUS) provides a promising approach of reducing anthropogenic emissions of the greenhouse gas CO2 while transitioning to more efficient and less polluting energy sources. Owing to their favourable flow and storage properties and relative abundance, carbonate basins comprise a significant proportion of the CCUS reservoirs. It is expecting that as CO2 is injected into deep, saline aquifers, it will dissolve into formation fluids, lower pH, and increase reactivity with hosting rocks. However, the primary concern is the ultimate fate of the injected CO2. To address this concern requires answers to the following key questions: (1) What are the key physical and chemical processes involved when CO2 is injected? (2) What are the associated important hydrogeochemical parameters? (3) What controls the feedback between flow fields and chemical reactions? In this seminar, I will present results and findings from experimental and numerical studies designed to answer these questions.

Biography: Dr. Xiangzhao Kong is currently a Research Fellow in the School of Civil Engineering of the University of Queensland. He has primary research interests in experimental and numerical modelling of complex flows in hydrogeological systems. He has expertise particularly in the field of multi-component and multiphase fluid flows in porous media, where he has published over 20 peer-reviewed journal articles. He holds a BEng (2003) and an MSc (2006) from the University of Science and Technology of China (China), and a PhD (2010) from Eidgenössische Technische Hochschule Zürich (Switzerland). He joined the University of Queensland in 2013 following a 3-year postdoctoral research in the Department of Earth Sciences, the University of Minnesota.
