Carbon Capture, Utilisation and Storage (CCUS) is a key technology to decarbonise cement production, as our sector faces unavoidable process emissions. These unavoidable process emissions come from the calcination of limestone, and amount to 60%-65% of cement manufacturing’s total CO2 emissions. CCUS is therefore essential for the sector to meet its carbon neutrality ambitions.
The captured CO2 can be stored in geological formations underground through what is called carbon capture and storage (CCS). Some raw materials and products, for instance concrete, are also able to store CO2 permanently.
The captured CO2 can also be used as raw material for production for short term and long-term lasting products through what is called carbon capture and utilisation (CCU). For instance, the production of synthetic fuels for transport, or of chemical products, can be done using the CO2 captured in cement plants
Carbon capture and geological storage (CCS) is fundamental for the decarbonation of the cement industry in the EU27. It is therefore critical to increase access to CO2 storage sites, develop CO2 transport infrastructure and continue to support the ongoing investments in the sector.
Furthermore, CCU should be fully recognised through an appropriate regulatory framework. The transition from today’s fossil fuels-based society towards a decarbonised Europe will indeed require the continuous use of CO2 as feedstock for some sectors.
