Carbon capture, utilization and storage in the cement industry

Cement and concrete are the most important construction materials but the manufacturing industry is also one of the largest industrial CO2 emitters. Accordingly, the EU plans to reduce the CO2 emissions by 80 % by 2050, when compared with 1990.This article highlights relevant facts & data about the global and European cement industry, what measures are taken for the mitigation of emissions, what are the most promising technologies and what are the prospective costs.

1 Introduction

In the cement industry, unlike most other industries, the process chemistry (decarbonisation of the limestone) rather than fuel combustion and electricity consumption is responsible for almost 2/3 of the CO2 emissions in clinker manufacturing. However, this proportion even increases with more advanced technologies that reduce fuel and power consumption. As an example: in the EU in 1990 the CO2 emissions from decarbonisation made up only about 54 % of the 170 million t (Mt/a) from the cement industry, combustion was responsible for about 38 %, power consumption for about 6 % and...
