本レビューは、鉄鋼業の脱炭素化における最新技術と実践を包括的に検討する。炭素回収・利用・貯留（CCUS）やグリーン水素を用いた直接還元、鉄鉱石の直接電解などの革新的技術に焦点を当て、現状のコスト障壁やパイロット段階にある技術の課題を分析する。また、既存施設のCCUS活用による近代化が新技術導入より経済的に有利であると指摘する。
English
This review comprehensively examines the latest technologies and practices for decarbonizing the steel industry, focusing on innovations such as CCUS, direct reduction with green hydrogen, and direct electrolysis of iron ore. It analyzes current cost barriers and challenges of pilot-stage technologies, noting that upgrading existing facilities with CCUS is more economically viable than building new ones.

📄 Abstract（原文）
Ferrous metallurgy is considered as one of the most difficult industries to decarbonize due to the high heat requirements of using carbon as a process feedstock, low profitability, high capital intensity, and long asset life. The authors review the latest researches in the field of technology and practice of decarbonization of cast iron and steel production. The paper evaluates existing and new decarbonization methods, as well as potentially revolutionary technologies. The analysis showed that there are several promising ways to produce iron on an industrial scale without CO 2 emissions. Currently, two advanced technologies for carbon-free steel production are at the stage of piloting and transition to demonstration projects. These are direct reduction of iron with “green” electrolytically produced hydrogen and direct electrolysis of iron ore. The review focuses on innovative technologies for carbon capture, use and storage (CCUS), especially promising technologies such as carbonization of steelmaking slags. The authors discuss the existing barriers to decarbonization and the tools that can help to overcome them. In general, although advanced decarbonization technologies are key levers for reducing emissions, they are still very expensive and are mostly at the pilot stage. From an economic point of view, it is more profitable to modernize existing facilities using CCUS than to build new facilities using alternative technologies. The review also highlights gaps in previous research works.
