摘要

The storage of liquid CO_2 at an ocean floor, one of promising measures to mitigate the global warming, requires 3500 m depth for the gravitationally stable storage, a breakthrough technology and a reasonable cost to realize, although it has large advantages such as the sequestration term longer than 2000 years. However CO_2 can be sent to the ocean floor by shallow release, if we can use the nature that the cold CO_2 to be shipped by a CO_2 carrier is much denser than the ambient seawater even at shallow depths. The National Maritime Research Institute (NMRI) conducted several joint field CO_2 release experiments with the Monterey Bay Aquarium Research Institute (MBARI, USA) since 1999 under the auspices of the NEDO, and proposed the improved COSMOS, CO_2 Sending Method for Ocean Storage, in which CO_2 is released into 200 m depth as slurry masses (mixture of dry ice and cold liquid CO_2). Since 2002, under the NEDO Grant, the NMRI started a new-international joint research, OACE, Ocean Abyssal Carbon Experiment with he MBARI and the University of Bergen (UoB, Norway), in order to accumulate the basic data on the long-term stability of stored CO_2 and its environmental effects around storage site.
