山西探路焦炉煤气制氢

Core Insights - The focus of the Shanxi coking industry is shifting towards the utilization of by-products from the coking process, particularly coke oven gas, as a growth point for the future [2][9] Industry Overview - Shanxi is a major coking province with a total coking capacity of approximately 142 million tons and an established coke oven capacity of 118 million tons [2] - In 2024, Shanxi's coke production is projected to be 92.116 million tons, accounting for 18.8% of the national total, making it the largest producer in China [2] - The domestic steel production has stabilized, with crude steel output expected to decrease from approximately 1.03 billion tons in 2021 to about 1.005 billion tons in 2024 [2] - The profitability of steel mills has declined significantly, with average production profits for hot-rolled coils dropping from around 800 RMB/ton in 2021 to less than 100 RMB/ton in 2024 [2] Financial Performance - The Shanxi coking industry is facing pressure, with an expected industrial added value growth rate decline of 0.4% in 2024, and total revenue projected at 235.6 billion RMB, a year-on-year decrease of 12.1% [2] - The industry is anticipated to incur a loss of 6.93 billion RMB in 2024, an increase in losses by 3.09 billion RMB compared to the previous year [2] By-product Utilization - The focus is on the recovery and utilization of various by-products from the coking process, such as coal tar and coke oven gas, to extend the coal chemical industry chain [2][3] - Coke oven gas has a high hydrogen content of about 60%, making it a valuable resource for hydrogen production [4] Hydrogen Production Potential - Shanxi can produce over 40 billion Nm³ of coke oven gas annually, with approximately 55% of it available for hydrogen extraction, representing a total development potential of over 13 billion Nm³ per year [5] - The cost of hydrogen production from coke oven gas is estimated to be between 10 to 12 RMB/kg, significantly lower than the local green hydrogen cost of around 20 RMB/kg [6] Industry Trends - There is a growing trend among Shanxi coking enterprises to enhance the utilization of coke oven gas for hydrogen production, with many companies actively investing in hydrogen energy projects [6][7] - The development of hydrogen energy heavy trucks has created new application scenarios for hydrogen produced from coke oven gas, with several companies already deploying hydrogen energy trucks [7][8] Future Outlook - The coking industry is expected to transition from a focus on coke production to a greater emphasis on coke oven gas, particularly as hydrogen metallurgy becomes more viable [9] - The industry is exploring various technological routes for steel production, including electric furnaces and hydrogen direct reduction, to reduce carbon emissions [9][10]
