Abstract Carbon capture and storage is a concept to reduce greenhouse gas emissions of energy production from fossil fuels. In oxy‐fuel combustion, the fuel is burned in a mixture of oxygen and recycled flue gas. This generates CO 2 ‐rich flue gas from which the CO 2 is easily separated and compressed.

Oxyfuel combustion can make a valuable contribution to improving the carbon balance of fossil fuel combustion. With this process, coal is combusted in an atmosphere consisting of pure oxygen and carbon dioxide (CO 2 ). This purer mixture burns at a higher temperature than natural air, thus increasing the efficiency of the combustion process.
