China has unveiled its first project in Lingyuan that fully converts coke oven gas into clean energy, marking a significant milestone for green transformation in the steel sector. Using advanced separation and synthesis technologies, the facility transforms waste gas into LNG, liquid ammonia, and hydrogen, maximizing resource efficiency.
The LNG produced can provide heating for 200,000 households for an entire month, while liquid ammonia finds use in fertilizers, cold-chain logistics, and even rocket propulsion. Hydrogen costs 30–50% less than conventional production, and its ultra-high purity opens doors to aerospace, electronics, and high-end chemical applications.
China generates around 210 billion cubic meters of coke oven gas annually. By utilizing just 30% of it, the steel industry could cut carbon emissions by 45 million tons per year and generate over 100 billion yuan ($14 billion) in industrial output, promoting a circular economy and supporting sustainable growth nationwide.
