Abstract
Fossil fuels have been extracted from the underground for a long time. This is not always free of risks, if one considers for example the so-called "fracking", where used fracking fluids or gases released uncontrolled could jeopardize the ground water.
By now, researchers discuss the process of pumping carbon dioxide, released by burning fossil fuels, back underground (already being implemented in test projects). Furthermore, nuclear waste is to be stored underground; energy in the form of heat or gas is to be temporarily stored underground; geothermal energy produces energy from the underground etc. The risks associated with all these activities must be described and, if possible, quantified by science in order to provide a solid basis for political and social debate. Flow, transport and deformation in porous media are one of the keys to a good understanding of these research questions. The lecture will provide insights using the above mentioned examples.
About the speaker
Prof. Holger Class is the deputy of the Department of Hydromechanics and Modelling of Hydrosystems (LH2) at the Institute for Modelling Hydraulic and Environmental Systems (IWS) of the University of Stuttgart. His research focuses on the development of model concepts for flow and transport processes in the subsurface with a variety of applications: storage of gases, precipitation processes in pore space, CO2 in caves, etc. Typically, the processes that interest Holger Class are coupled with bio/chemical or mechanical processes.
