Abstract: The invention is a method for removing carbon dioxide gas from ambient air using water and solid barium hydroxide in a reaction vessel. Incoming and outgoing water is supplied by freshwater and wastewater treatment plants through underground piping. The reaction vessel has an upper part and a jacket, which is heated by hydrogen gas. The vessel has a series of discharge ports on the upper part, and a conversion facility is located in an area of high greenhouse gas concentration. The barium hydroxide reacts with carbon dioxide to produce barium carbonate, which is sold along with the discharge water to generate revenue. The method provides a promising solution for mitigating the effects of climate change by reducing carbon emissions from the atmosphere.
