Inherent potential of steelmaking to contribute to decarbonisation targets via industrial carbon capture and storage.

ABSTRACT: Accounting for ~8% of annual global CO₂ emissions, the iron and steel industry is expected to undertake the largest contribution to industrial decarbonisation. Despite the launch of several national and regional programmes for low-carbon steelmaking, the techno-economically feasible options are still lacking. Here, based on the carbon capture and storage (CCS) strategy, we propose a new decarbonisation concept which exploits the inherent potential of the iron and steel industry through calcium-looping lime production. We find that this concept allows steel mills to reach the 2050 decarbonisation target by 2030. Moreover, only this concept is revealed to exhibit a CO₂ avoidance cost (12.5-15.8 €₂₀₁₀/t) lower than the projected CO₂ trading price in
