摘要

Disposal or storage of carbon dioxide comprises filling a mold with liquefied carbon dioxide under pressure at a subzero temperature, adding a precooled ballast material, cooling the mold to form dry ice, and sinking the dry ice in water to a depth of several hundred meters to form a mass of dry ice and water ice that remains at the bottom of the water.
