LONGi Hydrogen was named as finalist of the The smarter E AWARD 2025 in the Category "Oustanding Projects" for the application 3000 Nm³/h Electrolyzer in Hydrogen-Rich Blast Furnace Smelting.
In an industrial application, carbon is being substituted for green hydrogen during blast furnace smelting in Chinese Qinhuangdao. This project is an excellent example of how a step – that is often propagated worldwide – toward the decarbonization of chemical processes is being implemented on a large scale. The largest electrolyzers currently available are being used. The two units each have a capacity of up to 3,000 Nm³/h, making the system the world’s largest commercial green hydrogen production facility. Thanks to the use of hydrogen, this industrial decarbonization reduces carbon dioxide emissions by between 8 and 11 percent. The low power consumption of 4.2 kWh/Nm³ improves the economic viability of green hydrogen. This means that a hydrogen-enriched blast furnace smelting process is not only capable of considerably reducing emissions, but also of becoming a highly cost-effective technology. This process offers a wealth of opportunities, in particular when it comes to sustainable transmission in the steel industry.
