Abstract
Efficient and safe geological storage of CO2 involves multiple physical phenomena that manifest differently on different spatial and temporal scales. The mechanisms of CO2 trapping in different geomaterials are explored with live x-ray tomography under field-representative conditions (Thermo-Hydro-Chemo-Mechanical conditions). Advanced 3D image analysis enables the observation and quantification of the occurring processes locally and globaly that are otherwise difficult to follow with traditional lab testing methods. The real microstructure of the given material is used for the construction of realistic pore network or other analytical/numerical models.
Bio
Eleni obtained her PhD in Geomechanics from the University Grenoble Alpes, France, in 2017 in the context of geological nuclear waste disposal (Andra). Between 2017 and 2019 she did research as scientific collaborator in topics related to soil/structure interaction for offshore wind turbines and dams design. Eleni joined joined EPFL in 2019 and since then she is in charge of the CO2 storage activities of the Laboratory of Soil Mechanics (Prof. Laloui's group) where she's developing and exploring advanced imaging and analytical tools for a better understanding of the multi-physical and multi-phase phenomena that occur at different geomaterials before, during and after CO2 exposure.
