as iron ore, coal, limestone and steel scrap. About 75% of steel is produced using the BF-BOF route. First, iron ores are reduced to iron, also called hot metal or pig iron. Then the iron is converted to steel in the BOF. After casting and rolling and/or coating, the steel is delivered as strip, plate, sections or bars.

‘World first’ as hydrogen used to power commercial steel

Apr 28, 2020 More than 95% of the world’s hydrogen is today derived from natural gas and coal, causing nine to 12 tonnes of CO 2 emissions for every tonne of H 2 produced. Although hydrogen is a clean gas, releasing only water vapour when burned, there is no point replacing the coke, coal or LNG used in steel production with H 2 unless that hydrogen is produced from renewable energy (green) or
