Global warming is one of humankind's major concerns and many scientists are alerting. There is a strong need for actions to be taken here and now in order to limit the greenhouse gas emissions to the atmosphere. A worldwide effort is put in place, but solutions need to be validated and improved.


Carbon capture, utilization and storage (CCUS) is one of the viable solutions for reducing CO2 concentration in the atmosphere. CO2 storage in different conditions is a promising action and a big effort is devoted to foresee its multiple effects. Various CO2 trapping mechanisms contribute to the overall CO2 storage in a generic reservoir as a function of time. The CO2 trapped by stratigraphic trapping, i.e. the CO2 trapped by capillarity beneath the seal rock is dominant over the first decade following CO2 injection. Its importance is progressively diminishing at the benefit of the other, safer, storage mechanisms: CO2 storage as a residual phase when water re-imbibes the reservoir; CO2 storage by dissolution in the underlying aquifer; and CO2 storage by reaction with or as minerals. How fast and efficient these latter mechanisms are, is still poorly understood, and this project will address these questions mainly for solubility trapping, which could be much faster than anticipated due to instability and other unconsidered effects.

The aim of the CO2ES Industrial Chair (laureate of E2S UPPA's call for project: Senior Chairs, led by Fabrizio Croccolo) is to improve our understanding of the various CO2 trapping and transport processes involved in CO2 geological storage, and especially those processes that contribute to storage efficiency and safety. This will help in designing more efficient and safer large-scale projects.

The proposed research activities will be developed through 2 postdoctoral and 4 PhD students in close collaboration with the Industrial and institutional partners as well as international researchers.
