World’s first CO2 capture plant on vessel demonstrated


Japan Kawasaki Kisen Kaisha (“K” Line) has successfully separated and recovered carbon dioxide (CO2) from the exhaust gas of the coal carrier vessel ‘Corona Utility,’ which K Line operates for Tohoku Electric Power.

According to Mitsubishi Shipbuilding and Nippon Kaiji Kyokai’s “Research and Development for expanding marine resources technologies,” the ‘CC-Ocean’ project has been put onboard to verify the CO2 collection plant.

The captured CO2 had a purity of over 99.9 percent as a result of the demonstration, which is in accordance with the anticipated results. Experts from Mitsubishi Shipbuilding were onboard the vessel to manage, maintain and train its crew on how to work as well as measure, analyze and evaluate the captured CO2 in early August 2021 after the installation of a small-scale CO2 capture plant.

Ship crews have been running operations, measuring, and maintaining the plant since mid-September and will continue to assess the CO2 capture plant’s safety and operability in order to sort out any issues and conduct research and development for the future commercialization of the plant’s technology.

The company’s research, development, and introduction of environmental load reduction technologies, including the ‘CC-Ocean’ project, will be based on “K” Line Environmental Vision 2050, and we will contribute to actions targeted at meeting GHG reduction targets.
