山西探路焦炉煤气制氢

Core Viewpoint - Hydrogen metallurgy is considered the future of the steel industry, with a predicted reduction in coke usage and an increase in demand for hydrogen derived from coke oven gas [1][10]. Group 1: Steel and Coking Industry Overview - Shanxi province is a major player in the coking industry, with a total coking capacity of approximately 142 million tons and an expected coke production of 92.116 million tons in 2024, accounting for 18.8% of the national total [2]. - The national crude steel production has stabilized, with an estimated production of about 1.03 billion tons in 2021 and a projected 1.005 billion tons in 2024, leading to declining profits for steel mills [2]. - The industrial added value of the Shanxi coking industry is expected to decrease by 0.4% in 2024, with total revenue projected at 235.6 billion yuan, a year-on-year decline of 12.1% [3]. Group 2: Utilization of Coke Oven Gas - Coke oven gas contains a high hydrogen content of up to 60%, with the potential for Shanxi to produce over 40 billion Nm³ of coke oven gas annually, of which 55% could be used for hydrogen extraction [5]. - The cost of hydrogen production from coke oven gas is estimated to be between 10 to 12 yuan per kilogram, significantly lower than the local green hydrogen cost of about 20 yuan per kilogram [5]. - Shanxi's coking enterprises are increasingly focusing on utilizing coke oven gas for hydrogen production, with over 20 local steel companies, six of which have their own coking plants [5][6]. Group 3: Hydrogen Energy Applications - The development of hydrogen energy heavy trucks has created new application scenarios for hydrogen produced from coke oven gas, with several companies in Shanxi actively investing in this area [7]. - As of now, approximately 1,000 hydrogen energy heavy trucks are operational in Shanxi, with major contributions from companies like Meijin Energy and Jinnan Steel [7]. - The high cost of hydrogen energy vehicles, priced over one million yuan, poses challenges for wider adoption compared to traditional fuel and gas trucks [8]. Group 4: Future Trends and Strategic Shifts - Companies are shifting focus from traditional coke production to prioritizing the utilization of coke oven gas, indicating a strategic transition towards hydrogen energy [10]. - The steel industry is gradually moving towards lower carbon emissions by reducing reliance on coke and increasing the use of hydrogen and electricity in steel production [11]. - The development of hydrogen metallurgy is seen as a transitional phase, with coke oven gas serving as a more economical and stable hydrogen source compared to green hydrogen [11].
