K-Line, Mitsubishi and partners to test marine CO2 capture to achieve zero emissions

01 Sep 2020

Japanese maritime transportation company Kawasaki Kisen Kaisha, Ltd. (“K” Line) on Monday (31 August) said it will deploy a small-scale, marine-use demonstration plant for CO2 capture onboard a vessel and conduct research and development on a compact facility design in collaboration with project partners Mitsubishi Shipbuilding Co Ltd and non-profit organization Nippon Kaiji Kyokai (ClassNK).

The project is supported by the Maritime Bureau of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) as part of its programs to support research and development for advancing marine resources technologies, it added.

With the support of MLIT, “K” Line said it will collaborate with Mitsubishi Shipbuilding and ClassNK to install a small-scale CO2 capture demonstration plant onboard its vessel, conduct test operations of the plant, and measure its performance.

The marine-use CO2 capture demonstration plant will be based on an onshore plant and designed to capture a portion of a vessel’s gas emissions, it explained. 

This project 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.

These demonstration tests are aimed at promoting the development of more compact equipment required by marine environments along with the development of system requirements necessary for stable continuous operation at sea.

The following is the timeline for the project:

  • The two-year project will begin in August 2020 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 mid  2021, Mitsubishi Shipbuilding will begin to 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 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.

As the world’s first marine demonstration test, the project will provide invaluable insights into facilities design and technologies for capturing CO2 emissions and achieving zero emissions onboard vessels. 

Additionally, 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. 

In this way, the project will significantly contribute to the long-term reduction of greenhouse gas emissions.
