heavy industry emits about 22% of global greenhouse gas emissions: high temperature heat for heavy industry being about 10% of global emissions. The steel industry alone was responsible for 7 to 9 % of the global carbon dioxide emissions which is inherently related to the main production process via reduction of iron with coal. In order to reduce these carbon dioxide emissions, carbon capture and utilization and carbon capture and storage technology is looked at. Heavy industry has the advantage to be a point source which is less energy-intensive to apply the latter technologies and results in a less expensive carbon capture compared to direct air capture.
