摘要

The sub-seabed disposal of CO_2 is safer than the disposal of CO_2 in inland aquifers. Even if small amounts of CO_2 seeped out of sea floor, CO_2 would disperse and dissolve into sea water. On the surface of the sea, there exist no depressions where CO_2 may concentrate. Sediments under deep sea floor are very cool because the deep oceanic water is usually at a few degrees centigrade. CO_2 hydrate is formed in sediments under wide areas of ocean floor deeper than about 30Om. Virtually complete isolation of huge amounts of CO_2 is possible by the deep sub-seabed disposal. Liquid CO_2 with heavy suspension intrudes laterally under light unconsolidated sediments at sea floor deeper than about 3700m. Lateral intrusion technique for the super-deep sub-seabed disposal of CO_2 can protect the ecology on the sea floor.
