Under the goal of “carbon neutrality”, steel will become an important node in the multi-industry chain

Recently, the Hydrogen Metallurgical Technology Seminar "Inheriting HongSe Gene and Promoting Green Development" 
co-sponsored by Tianjin Jinnan District Government, Tianjin Energy Conservation Association and Rongcheng Group was held 
in Tianjin. Chu Mansheng, Dean of Northeastern University's Institute of Low-Carbon Steel Frontier Technology, delivered a 
keynote speech on the topic of "Research on the Application of Hydrogen in the Iron and Steel Industry". The content of the 
speech is as follows: In recent years, global temperature rise anomaly and atmospheric carbon dioxide concentration have 
continued to rise, and China's per capita carbon dioxide emissions have exceeded the world average. During the 75th United
Nations General Assembly on September 22, 2020, General Secretary Xi Jinping proposed on behalf of China that China will 
increase its nationally determined contributions, adopt more powerful policies and measures, and strive to reach the peak of 
carbon dioxide emissions by 2030, and strive to achieve it by 2060. Carbon neutral.
Under the goal of "carbon neutrality", steel will become an important node in a multi-industry chain, promoting social development
and industrial progress. At present, the main problems in my country's iron and steel industry are that the energy structure and 
process flow need to be optimized; the purity of steel is low and it is easy to rust; and the structure of steel products urgently needs
to be upgraded. Therefore, the steel industry is under great pressure to “carbon neutrality”. Facing the national “30·60” carbon 
emission reduction roadmap, the steel industry is based on energy conservation and high energy efficiency, focusing on the 
development of multi-industry synergistic carbon capture and utilization (CCU), supplemented by Energy substitution develops 
hydrogen metallurgy to achieve carbon neutrality, which is specifically manifested as:
01 Steel-Chemical Co-production
Based on carbon capture and utilization, the research and development and application of steel-chemical-hydrogen energy 
integrated network integrated CCU technology, through the collaboration of steel and chemical industry, provides the most 
reasonable and most thorough way of achieving net zero carbon emissions for my country's blast furnace-converter long process
steel industry. s solution.
02Substituting hydrogen for coal, hydrogen metallurgy
Substituting hydrogen energy for fossil energy, developing new hydrogen-based shaft furnace-electric furnace short process 
technology, realizing steel process innovation and energy structure optimization, and providing a new way for carbon-free steel 
production.
In my country's energy transition, hydrogen energy plays the role of "high-efficiency and low-carbon secondary energy, flexible 
and intelligent energy carrier, and green and clean industrial raw materials". Green hydrogen energy is considered to be the key 
to a carbon-free economy, and the application of hydrogen energy to metallurgy is an effective way to transform the metallurgical
industry into a low-carbon and green economy. At the same time, hydrogen is mainly used in hydrogen-rich reduction blast
furnaces, hydrogen-based shaft furnace direct reduction, and hydrogen metallurgical smelting reduction in steel production.
Rongcheng Group has the advantageous conditions to develop hydrogen metallurgy. The government, industry, university and
research institute collaborate to innovate and develop cutting-edge low-carbon steel smelting technologies, which can meet the 
high requirements of environmental protection in Beijing-Tianjin-Hebei and provide new ways and demonstration.
