6. Conclusions
- (1)
- China’s steel industry faces significant pressure to reduce carbon emissions with its massive production, its dominant reliance on coal for energy, and the primary use of blast furnaces and converters in production processes. The Chinese steel industry has limited potential to reduce process energy consumption alone to achieve carbon peaking and carbon neutrality. It relies on technological innovation and continues investing in low-carbon technology research.
- (2)
- China’s steel industry prioritizes dual-carbon goals, and companies and research institutions are taking significant action to achieve them. However, the development of high-efficiency carbon reduction technologies in China is in its early stages and relatively behind compared to other countries. It has yet to reach the level of industrial application, and there is still a significant gap in obtaining world-class carbon reduction technologies.
- (3)
- Many Chinese steel companies have not proposed clear dual-carbon plans, and more unified research activities are needed at the industry level. Companies should establish their dual-carbon plans, co-operate with relevant universities and research institutions in collaborative research, and strive to achieve dual-carbon goals as soon as possible.
