THE FUTURE ROLE OF CO_2-CAPTURE AS PART OF A GERMAN MITIGATION STRATEGY

摘要

The role that CCS technologies could play within the framework of an overall mitigation strategy will be presented in the form of scenarios with the example of Germany. As the presentation shows, the use of CCS can represent an interesting mitigation option in view of stringent CO_2 reduction goals. The scenarios, performed with the aid of the IKARUS model, however, also show that according to cost-efficiency criteria a large number of measures would have to be taken covering all energy sectors. CCS can at best represent one element in an overall strategy. If the existing total power plant capacity in Germany is extrapolated, a considerable number of outdated power plants will have to be replaced in the next 20 years. In order to make CO_2-free power plants available at that time, there is a need to enhance R&D efforts currently in progress. Furthermore, the application of retrofitting measures should also be considered.
