Researchers at the University of Birmingham have developed an innovative method for existing furnaces that could cut steelmaking’s CO2 emission by nearly 90%. The iron and steel industry accounts for 9% of global emissions because the coke (a type of coal) used to produce metallic iron from mined ore releases large quantities of carbon dioxide. The technology devised by Dr Harriet Kildahl and Prof. Yulong Ding aims to convert this carbon dioxide into carbon monoxide that can be reused in the iron ore reaction, subsequently lowering steelmaking’s emissions by up to 88%. If retrofitted in the remaining two blast furnaces in the UK, this method could save £1.28 billion in 5 years while reducing the country’s overall emissions by 2.9%. University of Birmingham Enterprise has filed a patent application and is looking for partners to take part in pilot studies or collaborate on further research.
