Methods of sequestering carbon dioxide (CO2) are provided. Aspects of the methods include precipitating a storage stable carbon dioxide sequestering product from an alkaline-earth-metal-containing water and then disposing of the product, e.g., by placing the product in a disposal location or using the product as a component of a manufactured composition. Also provided are systems for practicing methods of the invention.

What is claimed is: 1. A method of sequestering carbon dioxide, the method comprising:(i) contacting an alkaline-earth-metal-ion-containing salt water with CO2 from an industrial waste stream;(ii) removing protons from said alkaline-earth-metal-ion-containing salt water by an electrochemical protocol, wherein the electrochemical protocol produces no chlorine gas;(iii) subjecting the alkaline-earth-metal-ion-containing salt water to carbonate compound precipitation conditions to produce a man-made precipitated storage stable carbon dioxide sequestering product; and(iv) disposing of the precipitated storage stable carbon dioxide sequestering product to sequester carbon dioxide.
