Description
Summary:The European steel industry faces the challenge of transformation to climate neutral steel making over the next decades. A combination of hydrogen‐based direct reduction of iron ore with melter and chemical usage of steel mill gases is discussed. This transformation path allows to reach the climate goals economically with minimized effects on production network and steel quality, additionally providing sustainable feedstocks for the chemical industry. A transformation pathway for the steel industry is presented, combining H2‐based direct reduction of iron ores with electrical melter and chemical usage of steel mill gases. CO2 emissions can be reduced faster and residual emissions can be avoided. Additionally, the chemical industry can be provided with circular raw materials.
