Abstract Hydrogen direct reduction iron coupled with electronic arc furnace (H 2 DRI‐EAF) technology, as an important technology for decarbonisation in the and steel industry, has advantages of high electrification low carbon emissions. However, large demand hydrogen this relies significantly on production electrolytic hydrogen, leading to a substantial increase power consumption process. Moreover, use unclean source leads increases indirect emissions, reducing low‐carbon attributes technology. This study investigates integrated flexible operation mode plant. An illustrating method is utilised modelling entire process (PtH ) detail H DRI‐EAF plant, which includes natural gas, photovoltaic, wind self‐provided plants, capture storage (CCS) systems. A mixed integer linear programming (MILP) model developed comprehensive scheduling mill. The results case studies indicate that by reliably integrating renewable energy gas PtH system can fully consume output while ensuring smooth progress maximising emissions from total cost production.

Abstract The high‐value utilization of blast furnace slag (BFS) and steel (SS) as a valuable resource in the field carbon reduction represents green revolution, also is an indispensable path toward breaking through environmental constraints achieving high‐quality, sustainable development solid waste industry. Achieving recycling while harnessing untapped latent energy resources exploring their sequestration capabilities has become crucial avenue for further valorization utilization. BFS SS discharged from iron‐making or steel‐making furnaces carry significant amount heat, especially calcium oxide component SS, which gives it unique advantage comprehensive carbonation‐based This article discusses current research status low‐carbon‐waste‐heat production microcrystalline glass, cementitious materials, functional adsorbents, other products front‐end modification molten SS. report provides overview capture by utilizing offering insights into directions subsequent heat recovery, online quality adjustment, utilization, using
