The subsurface of the Earth is a major asset in the efforts to protect the biosphere from the hazards of climate change. The upper crust porous and fractured nature can either be harvested to extract energy or be employed to store the waste from industrial activities. Energy extraction/storage in geological media often involves complex physical processes and changes in flow, temperature and deformation, that are superposed with chemical reactions. Understanding and predicting observations at different scales of time and space, from laboratory to field, requires a trans-disciplinary approach that would unify experimental and theoretical findings with field observations. Examples of applications include carbon capture and storage (CCS), enhanced geothermal systems (EGS), supercritical geothermal systems, energy storage, hydrogen/compressed air storage, reservoir stimulation, hydro-fracturing/shearing, fluid injection-induced seismicity, and radioactive waste disposal. Contributions from analytical, experimental, geological, seismological, and numerical studies are welcome in this session.
