Cement, Energy and Environment

Figure.1 : Revolutionizing Cement with Carbon Capture & Storage Introduction The cement industry is a critical component of global infrastructure, yet it is also a significant contributor to greenhouse gas emissions, mainly CO2. Cement production is responsible for approximately 8% of global CO2 emissions (IEA, 2020). Emissions arise from two primary sources: the combustion of fossil fuels during the calcination process and the chemical transformation of limestone (CaCO3) into lime (CaO), which releases CO2. A comprehensive understanding of these processes lays the groundwork for effective CCS implementation (Worrell et al., 2001). As the demand for cement continues to rise with urbanization and infrastructure development, it becomes imperative to find sustainable solutions that mitigate the accompanying emissions. Carbon Capture and Storage (CCS) technology presents a promising solution for reducing the carbon footprint of cement production.
