Strategic measure analysis

Research and development of revolutionary breakthrough technology has become the inevitable future development of the industry, and the use of hydrogen instead of carbon is the ultimate direction of low-carbon development, energy reform, but also the fundamental way out of green.

At present, some China steel tube factories have carried out hydrogen metallurgy demonstration projects. For example, the oxygen blast furnace process experiment conducted by Baowu Ba Iron and Steel has completed the second stage test target. 1.2 million tons of hydrogen metallurgy demonstration project, using renewable energy such as wind energy and light energy, using supplementary air source containing about 70% hydrogen as reducing agent, producing 1 ton of direct reduced iron only produces 250kg of carbon dioxide, while selectively recycling the generated carbon dioxide. Jianlong Group has carried out a project to produce high purity cast pig iron with an annual output of 300,000 tons by hydrogen-rich melting reduction method in Wuhai. It is currently in the first stage, which can achieve 10,000 tons of hydrogen injection per year and reduce 112,000 tons of carbon dioxide emissions per year in the production process of rectangular steel pipe. In addition, Shanxi Jinnan steel landing operation of steel coking hydrogen co-production technology; Coal – based hydrogen metallurgy process of Jisco Group; Direct reducing iron process of gas-base shaft furnace in Shanxi Zhongjin Taihang Mining Co. LTD.
To achieve the “double carbon” goal, the essence is to change from high carbon to low carbon and even to near zero carbon emissions. If the iron and steel industry want to develop hydrogen metallurgy, it is necessary to solve the problems of hydrogen energy source and price, and formulate the strategic layout of hydrogen energy in advance. We all know that hydrogen energy is the ideal medium to promote the clean and efficient use of traditional fossil energy and support the large-scale development of renewable energy. For example, in April 2020, the Netherlands released a hydrogen energy policy, which aims to build 50 hydrogen filling stations, put 15,000 fuel cell vehicles and 3,000 heavy duty vehicles in 2025. Put 300,000 fuel cell vehicles on the road by 2030. In June 2020, Germany adopted a national hydrogen energy strategy, setting out a framework of action for the future production in mild steel tube, transportation and use of clean energy, as well as related innovations and investments.

At present, our country has not drawn up a road map of hydrogen energy development, and the hydrogen energy research is also scattered in various subplates. Hydrogen energy supply and application of China hollow section not only involve coal chemical industry, oil refining, steel making, coking and other traditional industries, but also involve hydrogen fuel cell vehicles, stationary fuel cell energy storage applications and other emerging industries. The top-level design of hydrogen energy requires collaboration between departments, industries and disciplines.
