  • Systems and methods for sequestering alkaline carbonates with captured CO
    Patent number: 12698695
    Abstract: A method for sequestering carbon dioxide (CO2) includes receiving an alkaline fluid stream and receiving an acidic stream. The alkaline fluid stream and the acidic stream are produced by a direct air carbon capture process and the carbonate includes air-captured CO2. The method also includes producing a pH balanced CO2 stream by mixing the alkaline fluid stream with an acidic mixing portion comprising 0% up to 100% of the acidic stream, and storing the pH balanced CO2 stream in a storage location. The storage location can include at least one of a subsurface location, on land, or in a water body. The storage location and the pH balanced CO2 stream are configured to provide long-term storage of the air-captured CO2.
