To respond to the climate crisis, subsurface low-carbon energy systems are urgently needed globally, including geo-energy extraction, carbon sequestration, nuclear waste disposal, geothermal energy recovery, and underground hydrogen storage. However, the heterogeneous nature of subsurface rocks and the coupling among physical, chemical, and biological processes make it challenging to predict potential risks and to improve the energy utilisation/storage efficiency.

Advanced static and dynamic imaging techniques (e.g. X-ray tomography, FIB-SEM, NMR, PET, TEM tomography) are critical to probe the physical and chemical properties of rocks and sediments, as well as the solid-fluid interactions under subsurface conditions. Novel image-based modelling provides an efficient way to understand and upscale the complex processes. This session focuses on recent advances in imaging and modelling from pore to reservoir scale, and the opportunities and limitations of applying these methods in hydrology, geology, geo-engineering, geomechanics, geochemistry, microbiology, soil science, and other subsurface activities in low-carbon energy systems.
