MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517090302 A) filed by Pronoe, Paris, on Sept. 22, for 'device and method for capturing and storing atmospheric carbon dioxide.'

Inventor(s) include Buceta, Juan; and Sdez, Nicolas.

The application for the patent was published on Oct. 10, under issue no. 41/2025.

According to the abstract released by the Intellectual Property India: "The invention relates to a method for capturing atmospheric carbon dioxide and to a device for carrying out same. The method comprises providing a saline stream (1) and calcium carbonate (7); producing an alkaline stream (5) comprising sodium hydroxide; and producing an acid stream (6) comprising hydrochloric acid. At least the production of the alkaline stream (5) or of the acid stream (6) comprises a step of electrochemically treating at least part of the saline stream (1). The method further comprises neutralising the hydrochloric acid by bringing it into contact in an acid reactor (AR) with the calcium carbonate (7) so as to obtain a liquid stream (8) of calcium chloride and a gaseous stream (9) of carbon dioxide; and producing a stream (10) of sodium carbonate by bringing carbon dioxide from the neutralisation step into contact in a base reactor (BR) with the sodium hydroxide from the alkaline stream production step. The method then comprises discharging the stream (10) of sodium carbonate flow into sea or ocean water, so as to increase its alkalinity and thus cause atmospheric carbon dioxide to be captured."

The patent application was internationally filed on Feb. 19, 2024, under International application No.PCT/FR2024/050218.
