1. A method comprising:
- acidifying a solution including dissolved inorganic carbon with aqueous HCl from an electrodialysis unit to form an acidified solution, wherein the electrodialysis unit receives a salt water solution and outputs the aqueous HCl and aqueous NaOH;
converting the dissolved inorganic carbon into carbon dioxide gas in response to acidifying the solution with the aqueous HCl from the electrodialysis unit;
vacuum stripping a first amount of the carbon dioxide gas from the acidified solution;
after vacuum stripping the first amount of the carbon dioxide gas, stripping a second amount of the carbon dioxide gas from the acidified solution; and
collecting the first amount of the carbon dioxide gas and the second amount of the carbon dioxide gas.
