Carbon dioxide removal could result in the use of lower-grade iron ore in a decarbonised net-negative emission steel industry

Reducing emissions from steel production is crucial for combating climate change while sustaining economic growth. This study explores how the steel industry could become carbon negative by mid-century, potentially removing up to a gigatonne of CO2 annually. By using a combination of innovative technologies like biomass-based reduction, carbon capture and storage, and slag carbonation, the industry could significantly cut emissions. Financial incentives for these reductions might also make lower-grade ores commercially viable. The costs of these green technologies could be offset by the value generated through carbon removal processes, making sustainable steel production both feasible and profitable.
