MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202531128148 A) filed by National Institute Of Technology, Rourkela, Orissa, on Dec. 17, 2025, for 'system for direct reduction of iron ore using electrolytic hydrogen and method for reducing thereof.'
Inventor(s) include Dinda, Dr. Soumitra Kumar; Hazra, Mr. Biplab; Mukhopadhyay, Mr. Sankhasubhra; and Dinda, Dalia Panja.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system (100) and a method (200) for direct reduction of iron ore (I) using electrolytic hydrogen. The system (100) includes an electrolysis module, a gas mixing module, a water bubbler (18) and a horizontal reduction furnace (20). The horizontal reduction furnace (20) includes an electric resistance heating zone (22), a quartz tube (24) sealed at both ends, a ceramic boat (26) associated within the quartz tube (24) for holding iron ore pellets (I), a temperature control module (30) configured to regulate furnace temperature. The system (100) further includes a gas inlet (20a) configured to supply hydrogen-nitrogen mixture into the horizontal reduction furnace (20) and a gas outlet (20b) for exhausting unreacted gases and water vapor. The system (100) provides reduction of iron ore (I) to lower oxide phases by using hydrogen as the sole reducing agent without generating carbon monoxide and carbon dioxide."
