MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051448 A) filed by Amrita Vishwa Vidyapeetham, Kollam, Kerala, on April 22, for 'hydrogen generation coupled with fluoride removal from seawater by quaternary liquid metal alloy-activated aluminium.'
Inventor(s) include Onattu Damodharan Jayakumar; Maneesha Vinodini Ramesh; Sabarinath Sankarannair; Sajithkumar K J; P. Nayana Krishna; and Aswathi K B.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a system (100) for on-demand hydrogen generation from seawater including an aluminium rod coated with a quaternary liquid metal alloy including gallium, indium, tin and bismuth, where the quaternary liquid metal alloy penetrates grain boundaries of the aluminium rod to disrupt a native oxide layer and forms a continuous micro-galvanic network to sustain aluminium hydrolysis, and a reaction vessel containing seawater and an ionic liquid bearing a nitrogen atom with a lone pair of electrons, where the ionic liquid forms a hydrophobic film on the surface of the aluminium rod to suppress re-passivation. A recovery unit (400) recovers the quaternary liquid metal alloy from a byproduct of aluminium hydrolysis by ultrasonication for reuse. Unlike conventional approaches limited to distilled water with poor recyclability, the present disclosure achieves rapid near-theoretical hydrogen yield from real seawater under ambient conditions with additional water treatment functionality."
