Abstract:Under the background of "emission peak" and "carbon neutrality", China's iron and steel industry must take the low carbon emission development road. Improving energy efficiency is one of the most manageable and effective measures. This paper analyzes the energy utilization characteristics of iron and steel industry, which are great energy saving potential and abundant secondary energy. Based on the principles of thermodynamic law, the minimum external loss of system, optimal driving force and cascade utilization of energy, this paper puts forward the innovative concept of combination for multi-energy complementation and energy storage in iron and steel industry. This concept includes complementation of renewable energy and secondary energy in steel factory, high grade and low grade energy, energy storage system and other innovative applications. In the medium-term and long-term, we need to take a higher stand and take the path of collaborative innovation in integration of energy, resources and environment, high efficiency, clean and low carbon emission, build an integrated energy using system of chemical industry, energy industry and ecology system, optimize and integrate all the parts reasonably, and achieve energy efficiency improvement and synergistic carbon emission reduction.
