Overview of geological storage options (storage principles for saline aquifers, HC fields and coal seams - volumetric storage and adsorptive storage); geology of reservoir and caprocks (rock types, trap types, petrophysical properties); properties of CO2 (depth dependency of density, viscosity, temperature); injectivity, pressure build-up (pressure management); trapping mechanisms (structural/stratigraphic, residual, dissolution, mineral); interaction and relative importance of trapping mechanisms (time dependent behaviour, site specific).
