Carbon Capture for CO2 Emission Reduction in the Cement Industry in Germany

Resumen

The share of global CO₂ emissions deriving from the cement industry is about 5%. More than 50% of these are process-related and cannot be avoided. This paper addresses the application of CO₂ capture technology to the cement industry. Analyses focusing on post-combustion technology for cement plants are carried out on the basis of detailed model calculations. Different heat supply variants for the regeneration of loaded wash solution were investigated. CO₂ avoidance costs are in a range of 77 to 115 EUR/tCO₂. The achievable CO₂ avoidance rate for the investigated cases was determined to be 70% to 90%. CO₂ reduction potentials were identified using CCS technology, focusing on the German cement industry as a case study. The results show that adopting carbon capture technology could lead to a significant reduction in CO₂ emissions.
