Mitsubishi Shipbuilding Co., Ltd., a subsidiary of the Mitsubishi Heavy Industries (MHI) Group, is reportedly in the news for its plans to conduct a testing procedure on an innovative CO2 capture system. The company is working alongside Nippon Kaiji Kyokai (ClassNK) and Kawasaki Kisen Kaisha, Ltd. (‘K’ Line) to undertake test operations and measurements for a ship-based CO2 capture demonstration unit, in a bid to verify the deployment of the equipment as a marine CO2 capture system.
Reliable reports claim that the MLIT (Maritime Bureau of Japan's Ministry of Land, Infrastructure, Transport and Tourism) is supporting this project as a part of its assistance project for the R&D of technological innovations in marine resource development. The demonstration is inclusive of converting the design of a current CO2 capture system for the onshore power plants to a marine environment, and then installing it on an actual ship currently in operation. Titled "Carbon Capture on the Ocean", this project intends to achieve CO2 capture at sea – a first across the globe.
Sources familiar with the knowledge of the matter claim that this project may last for two years. In August 2020, a hazard identification (HazID) study, post verification from ClassNK, will be introduced for designing the demonstration plant as well as the onboard installation. Mitsubishi Shipbuilding will be conducting the manufacturing of this CO2 capture demonstration plant and the safety assessment of the system. The production of the plant will be completed in mid-2021 and will be installed aboard a coal carrier, post operational tests at the factory, for Tohoku Electric Power Co., Inc., and operated by ‘K’ Line. Mitsubishi Shipbuilding, after this, via operational and performance confirmation in a marine environment, will be able to determine the specification requirements of the system as a marine-based device and will then also consider how the plant can be made more compact.
The knowledge gained through this demonstration experiment will be used for the advanced development of systems and technologies of the future, to capture CO2 released from the exhaust gases of a marine environment. Furthermore, the captured CO2 can also be recycled and then used as a as raw material in synthetic fuel, thereby contributing toward reducing GHG emissions, or a new source of CO2 for EOR (enhanced oil recovery) processes.
