MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202517064668 A) filed by The Trustees Of Columbia University In The City Of New York, New York, on July 7, for 'methods of improving co2 trapping and mineralization via water-alternating-gas cycling injections in subsurface rock reservoirs.'
Inventor(s) include Goldberg David S; and Nelson Claire A.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "Methods of trapping and mineralizing CO2 in a rock reservoir, such as one with a high concentration of mafic minerals, are provided. The method includes injecting a first quantity of free-phase, supercritical CO2 into the rock reservoir at a first rate and for a first duration; injecting a second quantity of water into the rock reservoir at a second rate and for a second duration; and repeating at least one of the above injection steps in an alternating fashion for a plurality of injection cycles. The first and second quantities, the first and second rates, the first and second durations, and a total number of the plurality of injection cycles are selected to improve trapping and mineralization efficiency in the rock reservoir and reduce the amounts of energy and water consumed. These systems and methods demonstrate efficacy in geographically diverse locations, broadening the available geographic storage for carbon dioxide sequestration."
The patent application was internationally filed on Dec. 11, 2023, under International application No.PCT/US2023/083286.
