ClassNK, in cooperation with Kawasaki Kisen Kaisha (“K” Line) and Mitsubishi Shipbuilding, a part of MHI group, will conduct test operations and measurements for a small scale ship-based CO2 capture demonstration plant, in order to verify the equipment’s use as a marine-based CO2 capture system.

The project is being conducted with support from the Maritime Bureau of Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT), as part of its assistance project for research and development of technological advancements in marine resources development.

The demonstration involves converting the design of an existing CO2 capture system for an onshore power plant to the marine environment, and installing on board an actual ship in service. This project, known as 'Carbon Capture on the Ocean' (CC-Ocean), is intended to achieve the first CO2 capture at sea.

The project is planned to last for two years. First, a hazard identification (HazID) study, with verification from ClassNK, will be launched for the design of the demonstration plant and the onboard installation. Manufacturing of the small scale CO2 capture demonstration plant and safety assessment of the system will be conducted by Mitsubishi Shipbuilding. The demonstration plant will be manufactured in mid-2021, and following operational tests at the factory, will be installed on board a coal carrier for Tohoku Electric Power operated by ”K” Line. Through operational and performance confirmation in an actual marine environment, Mitsubishi Shipbuilding will determine the system specification requirements as a marine-based device and will also consider how to make the plant more compact.

The knowledge gained will be used for future development of technologies and systems to capture CO2 from the exhaust gases of marine equipment and ships. Further, the captured CO2 can be recycled for use as a new source of CO2 for enhanced oil recovery (EOR) processes, or as raw material in synthetic fuel, providing a significant contribution to reductions in greenhouse gas (GHG) emissions.

To contribute to reductions in GHG emissions, ClassNK is engaging in safety assessment and verification on the entire project and will utilise outcomes to develop standards related to CO2 capture technology.
