- A limitation on the carbon storage potential to 5 Mton/y leads to a much slower CO2 reduction trajectory. In the period 2030-2040, there is a lower overall emission reduction. The sensitivity scenario Electrification_CCS5 reaches a 52% reduction by 2030, compared to 57% in the Central scenario and 59% in the Electrification scenario.
- In the medium-term, around 1 billion euro is saved every year by the reduced use of CCS technologies. The three most important savings are: reduced CO2 storage costs, reduced investments in CO2 capturing technologies and reduced energy losses inherent to the capturing process. Within the energy system, 1 billion euro is saved. However, the additional tax for the increased carbon emissions amounts to 1.5 billion euro every year.
- In the longer term (2050) and with only 5 million ton of CO2 storage, most of the storage is taken up by the cement sector showing that it is a priority sector for CCS.
- We observe an increased use of captured CO2 for feedstock production (2 million ton/ per year) and of electrification in the high value chemicals sector.
- The sensitivity scenario 'Electr. Carbon storage limit' reaches a 52% reduction by 2030 (58 million tonnes of remaining emissions) and an 80% reduction by 2040 (24 million tonnes of remaining emissions).
- Capturing of CO2 remains in both cases around 8 million ton per year in 2050. In the sensitivity run, 5 million ton goes to the carbon storage and the remaining CO2 is used for generating feedstocks (not visualised in the graph).
