Tokyo, February 2, 2022 – Mitsubishi Shipbuilding Co., Ltd., a Yokohama-based member of Mitsubishi Heavy Industries (MHI) Group, has entered into an agreement with Sanyu Kisen Co., Ltd., a Kobe-based company to manage the Shipping in both Japanese and foreign waters and calls for the construction of a demonstration test ship to transport liquefied carbon dioxide (LCO2) in connection with initiatives of the New Energy and Industrial Technology Development Organization (NEDO) in “CCUS R&D and Demonstration Related Project / Large-scale CCUS Demonstration in Tomakomai / Demonstration Project on CO2 Transport / R&D and demonstration project for CO2 Marine Transportation” (the Demonstration Projects). Construction begins at MHI’s Shimonoseki Shipyard & Machinery Works’ Enoura Plant, with completion and delivery scheduled for the second half of fiscal 2023.

The Engineering Advancement Association of Japan (ENAA), one of the organizations doing business related to the demonstration projects, will charter the vessel from Sanyu Kisen, the subcontractor, and operate it for the project purposes. On behalf of ENAA, three other project partners – Kawasaki Kisen Kaisha, Ltd. (“K” LINE), Nippon Gas Line Co.,Ltd. and Ochanomizu University – accelerating the research and development of the LCO2 Transportation technology and contribute to the cost reduction of CCUS technology and the safe long-distance and large-scale transportation of LCO2.

Although ships carry LCO2 used in the food industry and previously built and operated in Europe and Japan, the new ship to be built is expected to be the world’s first LCO2 Carrier specially designed for CCUS. Mitsubishi Shipbuilding will be responsible for all aspects from ship design to construction, including the cargo containment system, applying its gas handling technologies and know-how grown through the construction of LNG carriers (both LPG and LNG types).

CCUS is attracting attention today as an effective means of achieving a carbon neutral society. Because CO2 -Emission sites are often remote from sites chosen for carbon use or storage, LCO demand is expected to increase2 Forwarders who can transport their freight safely and economically. Through the experience gained during the construction of the world’s first LCO2 Carrier, purpose-built for CCUS, MHI Group will strengthen its current strategic business focused on the energy transition. The company will also continue its commitment to the development and delivery of LCO-related technologies2 Transport companies required to build the CCUS value chain to contribute to CO2 ecosystem development.

As part of its “MARINE FUTURE STREAM” growth strategy, Mitsubishi Shipbuilding has set itself two overarching goals: decarbonization through innovative technologies in the maritime industry such as the use of renewable energies and carbon recycling, and the effective use of sea spaces through autonomous operation and electrification. In order to achieve these goals, the company strives to pursue and implement various innovations relevant to the industry. The further development of LCO2 Transport companies and the active pursuit of commercial viability in this area are part of these initiatives, with the company’s ultimate goal being to make decarbonization a reality as a system integrator for shipping.
