Cement manufacture is responsible for around 7% of global anthropogenic CO₂ emissions. The process is unique in that around two-thirds of the direct CO₂ emissions are unavoidable as they come from the process chemistry rather than from fuel combustion. This makes reducing them particularly difficult, and carbon capture and storage is currently the only option that can reduce emissions by the extent required to allow cement manufacture to continue beyond the transition to low CO₂-emission economies. Post-combustion capture options, which are similar to those described in Chapter 4, are available. Equally, oxy-fuel combustion is possible. Pre-combustion capture can only deal with one-third of emissions from combustion, and so is generally not considered. Other cement-specific options exist, such as direct separation, and the synergies between calcium looping and cement manufacture are noteworthy. High CO₂ intensity coupled with the relatively low price of cement means that CCS is expensive per unit of cement manufactured. The lack of large-scale capture facilities means that the costs are rather uncertain, although several estimates are given in this chapter. A summary of existing pilot plants is provided, the challenges of rolling out carbon capture in the cement sector are discussed, and a way forward is suggested.
