About this Research Topic
In carbon geological storage, CO2 is captured from large stationary sources and then injected into a deep reservoir at high pressure and high temperature conditions where it is trapped. The trapping mechanisms that keep CO2 immobile within a storage reservoir include structural trapping, residual trapping, solubility trapping and adsorption trapping, which need to be fully understood. The injected CO2 also changes the chemical, physical and mechanical properties of the reservoir and that may lead to some negative effects: e.g. fault reactivation or CO2 leaking.
The goal of this research topic is to advance our understanding of the different trapping mechanisms, through the development of experimental methods, models and theories from the small micro-scale to the large field scale, in order to better understand long term carbon storage security.
Specific topics of interest for this research topic include, but are not limited to:
• Carbon geological trapping mechanisms;
• CO2 – rock – brine interactions ;
• Reservoir model studies;
• Pore-scale methods and modeling in carbon storage;
• Risk assessments;
• Theoretical, experimental, and numerical advances in Multiphysics transport phenomena;
• Case studies.
Contributors are welcome to submit through either the Geochemistry section of Frontiers in Earth Science or the Carbon Capture, Utilization and Storage section of Frontiers in Energy Research.
