“K” Line to test CO2 capture plant on coal carrier

The project is said to be the world’s first marine demonstration of a CO2 capture plant

“K” Line has announced it will deploy a small-scale CO2 capture plant onboard a coal carrier in a two-year demonstration project.

The shipowner will be running the project with Mitsubishi Shipbuilding and ClassNK, with support from Japan’s Maritime Bureau of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).

In a statement issued today (31 August), “K” Line said that the demonstration plant will be based an onshore plant and ‘will not only verify the efficacy of capturing and storing CO2 from a vessel’s gas emissions, but also the operability and safety of CO2 capture facilities at sea’.  

Importantly, the project will look to foster the development of the more compact equipment that will be required in marine environments along with the development of system requirements necessary for stable continuous operation at sea.

The project will begin with the launch of a HAZID (hazard identification) evaluation of the demonstration plant and deployment on vessels, with verification from ClassNK. Mitsubishi Shipbuilding will begin development and construction of a small-scale CO2 capture demonstration plant and evaluation of system safety.

In the middle of 2021, Mitsubishi Shipbuilding will begin test operation of the demonstration plant at its factory, followed by deployment of the plant on “K” Line’s CORONA UTILITY, a thermal coal carrier operated for Tohoku Electric Power Co., Inc.

By the end of fiscal year 2021, the project partners will start operating the demonstration plant on-board the vessel and measuring the system’s performance under marine conditions, with the aim of jointly developing a new marine system for vessels.

The captured CO2 is expected to be recycled as a new CO2 source for Enhanced Oil Recovery (EOR) processes or as raw material in synthetic fuel through methanation.
