About this Research Topic
The world is at a tipping point: the current effects of dangerous climate change are already evident in extreme weather events throughout the world: it is estimated that the climate has already warmed by over 1oC and we need to limit the change to 1.5oC to avoid more significant environmental damage, than we are currently witnessing. While there is huge growth in renewable energy and low-carbon technologies, the frank truth is that we continue to burn fossil fuels: the economic costs and technological challenges associated with a complete transition away from these fuels - particularly for heating, heavy industry and as a swing producer when renewables are intermittent - are huge. Somehow the CO2 from these fuels must be prevented from entering the atmosphere. Geological storage of CO2 is now the key technology to mitigate anthropogenic greenhouse gas emissions.
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.
