Abstract

Abstract

Promoting the low-carbon development of the iron and steel industry has become an important part of achieving carbon peaking and carbon neutrality in China, as it's a major energy consumption and CO₂ emitting industry. In this paper, we analyzed the key abatement technologies and the abatement costs for iron and steel industry under three types of scenarios and four decarbonization aspects:energy structure adjustment, process structure optimization, energy saving and emission reduction technology promotion, and CCUS technology application, to reveal the emission reduction priority of each technology. The results indicated that, under the steady development scenario, the average abatement cost for iron and steel industry was RMB 433/t CO₂. The total abatement cost of all the technologies was RMB 210 billion, with a total carbon abatement volume of 490 million tons. Among the various abatement technologies, scrap-EAF had the best economic efficiency, contributing nearly half of the total abatement in the iron and steel industry, indicating that the scarp-EAF becomes an essential measure for China's iron and steel industry to achieve the target of carbon peak and carbon neutrality.
