MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521123115 A) filed by Greenxcel Technologies, Ahmedabad, Gujarat, on Dec. 6, 2025, for 'an eco-efficient hydrogen generation system and method from industrial acid waste and metal scrap.'
Inventor(s) include Ramesh K. Guduru; Krishnaveni Adepu.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system (100) and method for converting industrial acid waste (101a) and metal scrap (101b), including iron-based scrap, into hydrogen gas (110). The first chemical conversion chamber (101) uses thermal activation to produce hydrogen gas (110) and an iron-ion-rich liquid (101c). An activator supply unit (102) provides activator ions (102a), which include chloride radicals or sulfate radicals or nitrate radicals or a combination of chloride radicals or sulfate radicals or nitrate radicals, to depassivate the metal scrap (101b). The iron-ion-rich liquid (101c) then passes through a primary filtration unit (104) and enters a second chemical conversion chamber (105) for reaction with a neutralizer (106a), an oxidizer (107a), and water (103a) to form iron oxyhydroxide solids (104b) and a secondary filtration unit (108) separates the iron oxyhydroxide solids (104b)."
