Iron- and steelmaking is the largest single industrial CO 2 emitter, accounting for 6.5% of all CO 2 emissions on the planet. This fact challenges the current technologies to achieve carbon-lean steel production and to align with the requirement of a drastic reduction of 80% in all CO 2 emissions by around 2050. Thus, alternative reduction technologies …
