CO2 capture and storage (CCS) is internationally recognized as a bridging technology for achieving a low carbon energy society. Since fiscal year 2008, the Ministry of the Environment has started an environmentally-friendly CCS project to demonstrate CO2 separation and recovery technology at thermal power plants and to develop a CCS introduction method suitable for Japan. In this joint project of industry-government-academia collaboration, the University of Tokyo is studying environmental impact considerations such as leakage suppression and a restoration method of CO2 stored under the seafloor as well as a detection method at the time of leakage from the seabed. As part of a smooth introduction method by the ship, we are investigating sea transportation and offshore submarine storage system.
