Scientists from the ukasiewicz Research Network - Institute of Ferrous Metallurgy (IMŻ), in collaboration with the University of Technology of Czestochowa, have reduced the number of costly intermediate steps in steel production using innovative hydrogen technologies.
On my page </a > on Facebook, scientists note that the method they have invented makes it possible to produce steel directly from iron ore without going through the pig iron stage and without releasing carbon dioxide. However, its use on an industrial scale is much more expensive than the blast furnace process. Therefore, Polish technologies can enter industrial production no earlier than 2030.
“The developed method of hydrogen production can be part of the process of making steel directly from iron ore, using this gas as a reducer according to a patented method at the Institute of Ferrous Metallurgy. The use of the technology according to the developed method will significantly reduce CO 2 emissions into the atmosphere, by more than 70% during the steel production process. Due to the low energy resources for hydrogen production according to the developed method - many times lower in comparison with the water electrolysis method - it can be used for the production of hydrogen for other economic sectors, ”noted the Polish inventors.
Scientists from the ukasiewicz Institute of Ferrous Metallurgy have already received a patent document for an invention called "Method of producing steel directly from iron ore".
