| Dear all, We had a slight hic-cup with our guest speaker, so this evening’s meeting has changed to: “Using the subsurface for our future energy needs: the scientific challenges” Suzanne Hangx (Utrecht University, Assistant Professor) Agenda 19.00 Socialization ½ hour 19.30 Presentation starts Date & Time: April 12th, 19 pm-20:30pm Click HERE to join the meeting via Teams Please save the new calendar file from here. Abstract Activities in the subsurface take the reservoir-caprock-fault system out of its natural physical and chemical equilibrium. On the long term, this may result in phenomena such as surface subsidence and/or induced seismicity due to deformation of the subsurface system. With global energy demand soaring and the climate-threat of anthropogenic CO2 emissions increasing, we are now looking into new ways to use the subsurface to meet our needs. On the one hand, large-scale subsurface CO2 storage is considered to reduce CO2 emissions. On the other hand, there is a drive for the production and storage of renewable energy sources, such as the production of geothermal heat or the storage of hydrogen fuel generated from renewable energy. However, what will be the impact of these activities, pumping around vast volumes of fluid, on the mechanical behaviour of the subsurface? In this contribution, I would like to outline what we can learn from O&G operations and CO2 storage, and what scientific challenges we will still need to address to ensure safe, subsurface operations during future activities such as geothermal energy production and/or hydrogen storage. 
Biography Dr. Suzanne Hangx is an assistant professor at the High Pressure and Temperature Laboratory of the Department of Earth Sciences at Utrecht University since 2017. She obtained her PhD from Utrecht University in 2009 on the topic of CO2 storage, for which she was awarded the Outstanding Young Scientist Award in the division of Energy, Resources and Environment of the European Geosciences Union in 2012. After her PhD, Suzanne worked at Shell Global Solutions, in the Subsurface Containment team for almost 5 years, before returning to Utrecht. These days, she still works on CO2 storage, but also other energy-related challenges pertaining to the subsurface, such as for hydrogen storage and geothermal energy production. Her key research focus is to identify and quantify the grain-scale interactions that occur in reservoirs and caprocks, due to fluid-rock interactions resulting from fluid injection and extraction, and how they affect the mechanical behaviour of rocks.
