Description:

Bio: Guido Musso graduated in civil engineering from Politecnico di Torino, where he obtained his PhD in 2001 with a thesis on electrokinetic processes in clayey soils. Since 2021, he has been Full Professor of Geotechnics at the same university, where he also serves as Director of the Geotechnical Laboratory. He is the author/co-author of more than 60 scientific publications in peer reviewed journals, mainly related to the experimental study of the multiphysical response of soils and to applications of environmental and energy geotechnics. He has been a member of the editorial board of Géotechnique (ICE, London). He is the Italian correspondent for TC308 – Energy Geotechnics of the ISSMGE (International Society of Soil Mechanics and Geotechnical Engineering).

Abstract: Climate change mitigation and energy transition require the development of new knowledge and design solutions in many fields of engineering, including geotechnics. CO2 sequestration and storage requires capturing CO2, either at source or from the atmosphere, and storing it in deep geological layers with high permeability and porosity, where it is trapped by physical and chemical mechanisms. Similarly, energy transition involves the use of hydrogen as an energy carrier, cyclically stored and withdrawn from large-capacity tanks according to seasonal energy consumption. In this case too, storage can take place in deep geological strata. During the seminar, the geomechanical aspects governing the distribution of fluids in the subsoil and the relative stress structure will be discussed. With reference to the research conducted at Politecnico di Torino in recent years, specific aspects of underground fluid storage will then be analysed, such as the experimental determination of the maximum injection pressure and the fatigue life of the cap rock, i.e. the maximum number of cycles permissible in the case of cyclical fluid production and storage histories, showing both original experimental evidence and modeling.
