Carbon Capture and StorageTechnologies & Measures
|Technology or Measure||Energy Savings Potential||CO2 Emission Reduction Potential Based on Literature||Costs||Development Status|
|Post Combustion CO2 Capture Using Absorption Technologies|
Thermal and electrical energy use increases by 1 - 3.5 MJ/t-clinker and by 50 to 90 kWh/t-clinker, respectively.
Up to 90% of the CO related to clinker production can be captured. CO2 emissions linked to the absorption and regenertion steps will need to be taken into consideration.
Reductions of 740 kg CO2/t-clinker are estimated.
Investment costs are estimated to be €100 - 300 million in 2030 and € 80 - 250 million in 2050.
Operational costs are estimated to be €10 - 50/t-clinker for 2030 and € 10 - 40/t-clinker for 2050.
|Carbonate Looping Technology|
Calcination related CO2 emissions (~ 0.52 t CO2/t-clinker) can be avoided if the spent sorbent is used to replace CaCO3.
|Post Combustion Capture Using Membrane Processes||Not available.|
More than 700 kg CO2/t-clinker can be reduced.
Specific costs are estimated to be €45–50/t CO2 for 2015 and €25/t CO2.
