In response, decarbonization measures such as establishing or switching to hydrogen-based (H2) steel production can be implemented either in forthcoming (greenfield) sites or existing (brownfield) facilities.4 The latter opportunity requires existing equipment to either be retrofitted or for the facility to possibly be completely rebuilt in order to implement a decarbonized production process. The optimal steps to decarbonization will differ by location and site, depending on the likes of technical feasibility, existing infrastructure, market demands, operating costs (ie, the price of renewable electricity, the price of scrap), and the regulatory environment."
Another matter altogether is the need for stable supplies of energy. Buffering of energy needs is easy in a coal-fired system. Other types of planning are necessary with other sources of energy.
