✦ Synopsis

The role that carbon capture and storage (CCS) technologies could play within the framework of an overall CO 2 mitigation strategy is examined in the form of scenarios up to 2030 with the example of Germany. As the calculations show, 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 optimization 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. The model results show that a mitigation goal for 2030 corresponding to a 35% reduction of CO 2 as compared to 1990 is necessary to trigger a significant contribution of CCS. As an alternative to a CO 2 restriction, we also calculated reduction scenarios based on CO 2 penalties. These scenarios showed that a penalty price of approximately 30 h/tCO 2 is necessary before CCS can be included in the model.
