China’s Dalian Shipbuilding has successfully completed sea trials for the first LNG-powered, wind-assisted liquefied carbon dioxide (LCO2) carrier.
The vessel is being built for Northern Lights, a joint venture (JV) formed by energy giants Shell, Equinor, and TotalEnergies.
Northern Lights’ LCO2 Carrier Fleet
Northern Lights has commissioned a total of three specialized LCO2 carriers, which combine LNG-powered propulsion with wind-assisted technology and air lubrication systems. These features significantly reduce carbon emissions compared to conventional vessels.
Construction of the first two ships began in November 2022, marked by the initial steel-cutting ceremony, followed by the keel-laying ceremony in April 2023. Both ships feature pressurized cargo tanks specifically designed for transporting liquefied CO2, helping to lower their carbon intensity.
Key Features of the Vessels
The two sister ships, each with a cargo capacity of 7,500 cubic meters, are expected to begin operations in 2024. They were independently designed and constructed by Dalian Shipbuilding, featuring two full-pressure C-type liquid cargo tanks. These specialized tanks, made from materials capable of withstanding temperatures as low as -35°C, enable the safe transportation of up to 7,500 cubic meters of liquid CO2.
Additionally, the vessels meet the most advanced Energy Efficiency Design Index (EEDI) standards, with sulfur oxide and nitrogen oxide emissions compliant with stringent environmental regulations.
Successful Sea Trials and Future Plans
During the sea trials, the ships underwent a series of critical performance tests, including the main engine navigation test. According to Dalian Shipbuilding, all key performance indicators either met or exceeded expectations.
In June 2023, the shipyard also began construction on the third vessel in this series, with the steel-cutting ceremony marking the latest milestone in the project.
CO2 Transport and Storage
Upon completion, the LCO2 carriers will transport captured and liquefied CO2 from industrial emitters to Northern Lights’ receiving facilities in Øygarden, Norway. Once there, the CO2 will be temporarily stored in onshore tanks before being transferred via pipeline to an offshore reservoir for permanent storage, located 2,600 meters below the seabed. Northern Lights is scheduled to begin operations in 2024.
