Carbon Dioxide Capture and Storage (CCS) denotes the extraction of carbon dioxide (CO₂) from point sources, e. g. flue gases of power stations, and its storage in deep geologic reservoirs. CCS is considered a potential option to reduce CO₂ emissions from anthropogenic activities and their climatic impact. more

The CO₂Seals project investigates the sealing efficiency and long-term integrity of geologic strata (caprocks, seals), overlying potential CO₂ storage formations. The experimental program comprises petrophysical, mineralogical, geochemical and mechanical methods. Numerical models are used to reproduce the observed geochemical and fluid-transport processes on the experimental scale. Subsequently, these models are applied for upscaling to reservoir scale. more

The main objective is to establish reliable criteria for the appraisal of sealing efficiency, long-term integrity and leakage rates for low-permeable geological strata overlying potential CO₂ reservoirs. One aspect of the CO₂Seals project is to obtain a better understanding of the effects of CO₂-water-rock and CO₂-rock interactions on the sealing efficiency of caprocks. more

CO₂Seals is one of 11 research projects addressing Technologies for safe and permanent storage of the greenhouse gas CO₂, funded by the German Federal GEOTECHNOLOGIEN program, within the key research area: Investigation, Use and Protection of the Underground. CO₂Seals is a 3-year project which started in August 2008."
