Kohlendioxidabscheidung und geologische Speicherung (CCS) - ein Überblick.

Achieving the nationally and internationally defined climate policy goals regarding the reduction of anthropogenically emitted greenhouse gas concentrations in the atmosphere is an enormous challenge. To this end, it can be assumed that underground storage of >100 billion tons of CO2 by the end of the century is necessary, as the capacity of natural storage (e.g. forestation, wetland restoration, oceanic CO2-sinks, biochar and soil carbon sequestration) is restricted, the permanent removal of CO2 from the atmosphere through carbon capture and use (CCU) is limited by the product lifetime. At the same time emissions cannot be curbed quickly enough. The principles of carbon capture and storage (CCS) have been researched internationally, the potential storage volumes have been determined and the feasibility of geological storage has been demonstrated by successful projects (e.g. the first European onshore pilot plant Ketzin in Brandenburg, commercial plant Sleipner in Norway, etc.). Neighbouring countries such as Norway, Denmark, UK and the Netherlands are going further and implement projects. Germany has the technical and scientific potential to realise the commercial implementation of CCS in Germany and could thus make a significant national contribution to climate policy goals.
