Mitsubishi Shipbuilding Co., Ltd. is developing liquefied CO2 carriers as a means of transporting CO2 for establishment of a Carbon dioxide Capture, Utilization and Storage (CCUS) value chain, and onboard CO2 capture systems to reduce CO2 emissions from ships. In the development of liquefied CO2 carriers, we select materials for the tank system, design the structures and create the operation process from the perspective of optimizing the entire CCUS value chain, and in the future, we will establish the technology by building a demonstration ship, which will be the world's first liquefied CO2 carrier for CCUS. As for onboard CO2 capture systems, we will continue further development toward commercialization based on the results of the demonstration of a capture system conducted in a demonstration plant in fiscal 2021. Through these activities, we will provide the optimal total solutions for business operators that aim to realize a carbon neutral society.
