SANJEEV GUPTA: How steel can go carbon neutral by 2030. One approach has been to simply to make less primary steel – and my own company, Liberty Steel Group, has been a long standing champion of Greensteel, which is based on recycling steel scrap in electrically powered furnaces using renewable energy where possible. If when using fossil fuel based energy, this method has less than a third of the emissions compared with the primary steel making route. When steel recycling is combined with renewable power the savings are almost 100pc. A future vision of hydrogen-powered steelmaking has been viewed, in the past, as too technically and economically challenging. But the technology has moved on by leaps and bounds. Rather than the traditional use of natural gas or coal, it is now proven that hydrogen can be used to reduced iron ore to iron which is then melted in electric arc furnaces on its own or combined with steel scrap to make primary steel. The by-product from reducing iron ore with hydrogen is water rather than CO2. Liberty Steel Group isn’t alone in exploring this – SSAB and ArcelorMittal, for example, are advancing working pilot plants to prove this technology at scale.
