As an effective means to realize a carbon-neutral society, CCUS (Carbon dioxide Capture, Utilization and Storage) is attracting attention. In order to realize a CCUS value chain, a means of transporting the captured CO2 to the storage site is necessary. Liquefied CO2 carriers are considered to be a safe and low-cost means of transportation and their demand is predicted to increase in the future, so there are high expectations for the technology to be established. EXCOOL (hereinafter referred to as "the vessel") is a liquefied CO2 (LCO2) and liquefied petroleum gas carrier built at Shimonoseki Shipyard & Machinery Works of Mitsubishi Heavy Industries, Ltd. for the purpose of being offered to the New Energy and Industrial Technology Development Organization (NEDO) project "Research, Development and Demonstration of CCUS Technology/Large-scale CCUS demonstration testing at Tomakomai/Demonstration testing on CO2 Transportation". The vessel was delivered in November 2023 and will be utilized for the aforementioned NEDO demonstration testing.
