On September 2, Mitsubishi Shipbuilding got Approval in Principle (AIP) of Bureau Veritas of French classification society on the basic design of cargo tank system for loading on LCO2 transportation ships.

In the CCUS which is expected as a prospective measure to reduce CO2, it is indispensable to have transportation means of CO2 from the source of emission to the place of use. One of such means is transportation by ship, but there has been no practical development to transport a large volume of CO2 in the past.

Mitsubishi Shipbuilding has been engaged to develop a CO2 loading tank since over 20 years taking advantage of its technologies fostered in the field of shipbuilding of carriers of gases like LNG. It seems that the AIP approval obtained this time has made the company go one step ahead toward realization of the aimed development.

The approved type of Tank C in a cylindrical shape is used for an LNG fuel transportation ship or the like, and is assumed for use at lower than -20℃ and 20 bar (2MPa).
As for the materials, sizes and load capacity, the company is going to examine and produce in an appropriate way to meet an individual project respectively.

On August 26 before the approval, the company started feasibility researches toward the development of LCO2 carriers in collaboration of TotalEnergies SE of French Energy company.

The collaboration has been realized out of the fact that Mitsubishi Heavy Industry of the parent company has long been in contact with each other exchanging information as to the common theme to realize a decarbonization society, and both will keep discussing so that they can realize an actual implementation of operation in the future.
