1) The proposed process will simultaneously remove carbon dioxide (CO2) from the atmosphere and extract lithium (Li) and other metals from brine. 2) The brine could be any salt containing solution, including: produced water from oil industry, sea water, or salt water from lakes; 3) During this process, we will also provide H2, Cl2 and fresh water. 4) The benefit of this technique: 1) CO2 capture; 2) Critical minerals extraction for battery (including Li); 3) Fresh water generation; 4) Hydrogen production; 5) Other useful resources generation: metal salts, and Cl2. 6) We will use renewable energy.
