Cement production is a highly energy-intensive process. Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricity-consuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant.
There is potential to blend clinker with alternative materials to reduce the need for clinker itself and thus help reduce the climate impacts of the cement-making process. Modern cement plants are equipped with …
To fully decarbonise the sector, process emissions from the clinker-making process need to be addressed, regardless of the heat source. Part of the solution will need to be CO 2 capture – applied to both the combustion and process emissions, or combining a zero-CO 2 heat source with the capture of concentrated process emissions.
