The world’s first liquefied CO2 test vessel will be built

A BAEBOAT charter contract has been signed by the Engineering Advancement Association of Japan (ENAA) and Sanyu Kisen Co, for the world’s first liquefied carbon dioxide (LCO2) carrier and tank system.

ENAA led the development of a demonstration test vessel and specifications for the LCO2 tank system. Sanyu Kisen has ordered the manufacture of the tank system based on ENAA’s R&D and the construction of a demonstration test vessel equipped with its tank system, from Mitsubishi Shipbuilding.

The vessel will be built at MHI’s Shimonoseki Shipyard and Machinery’s Enoura plant.

Upon delivery, ENAA will charter the demonstration test vessel from Sanyu Kisen to perform research and development and demonstration tests to establish the LCO2 vessel technology. Specifically, to transport LCO2 for Carbon Capture, Utilization and Storage (CCUS).


ENAA will work with K-Line, Nippon Gas Line and Ochanomizu University to accelerate R&D of LCO2 transportation technology and contribute to cost reduction of CCUS technology.

“In the demonstration project, we plan to use the vessel to collect operational data under various loading conditions and in various weather and sea conditions,” ENAA said in a statement.
