Clean energy for steel pipe industry

Steel industry carbon peak carbon neutral difficulties
As a key carbon emission industry, China’s iron and steel industry faces four major challenges in low-carbon transformation:
First, the energy composition is mainly coal;
Second, large steel consumption and crude steel output;
Third, the number of steel pipe suppliers, large differences;
Fourth, the carbon emission mechanism is complex.

At the same time, our iron and steel industry also face four problems of unbalanced and inadequate development:
First, under the strict carbon reduction target task, the technical support capacity is still insufficient;
Second, under the requirements of increasingly perfect policy development, the supporting technical tools of the industry are not perfect;
Third, under the high quality and low-cost development strategy of round steel pipe, the marginal cost of technological carbon emission reduction is increasing;
Fourth, under the higher requirements of ecological civilization construction, the basic capacity of the industry itself is still weak.
Steel industry carbon peak carbon neutral path
Low-carbon development depends on scientific and technological progress. We should reduce carbon in the process of development and develop in the process of reducing carbon. For the low-carbon development of Chinese iron and steel industry, the carbon reduction of blast-converter long process, which accounts for 90%, should be accelerated.
China’s iron and steel industry to achieve “double carbon” five stages of steady progress. There are various carbon reduction paths at different stages of development, and various comprehensive factors such as forced mechanisms and emission reduction costs of China hollow section should be taken into account to make the optimal ranking.

Among them, for the steel industry to achieve deep decarbonization and carbon neutrality, the rational layout of the three paths is the most critical:
The first is to use scrap steel resources to develop “green electricity” arc furnace short process steelmaking;
The second is to develop “green hydrogen” metallurgy, and at the same time play the synergistic carbon reduction effect of non-blast furnace ironmaking and electric arc furnace short-process steelmaking;
Third, developing carbon capture, utilization and storage technologies of square steel pipe.
The first two paths are closely related to the development of new energy.
Development of clean energy such as “green electricity” and “green hydrogen” is an important support for China’s iron and steel industry to achieve carbon peak and carbon neutrality. In recent years, China’s iron and steel industry has intensified efforts to promote the development and utilization of solar energy, wind energy, biomass energy, hydrogen energy and other clean energy. Iron and steel enterprises are studying and exploring hydrogen smelting technology, including non-blast furnace ironmaking, and actively carrying out “green electricity” trading work.
