Knutsen NYK Carbon Carriers AS (KNCC), a joint venture established last year between Japanese shipping major NYK and Norway’s Knutsen Group to transport liquid CO 2 , revealed that its LCO2-EP technology to store and transport liquefied CO2 at ambient temperature tested and proved at the test-rig facility through the CLIMIT Program.
CLIMIT is a Norway-based funding organization that supports the development and demonstration of CCS technologies.

Under the project, supported by NOK 4.69 million ($437K) from CLIMIT, the LCO2-EP tank design was tested on an experimental scale at ResQ’s Safety and Emergency Response Centre close to the city of Haugesund. The technology has been examined in connection with both conversions and new constructions, CLIMIT said.
The test rig consists of two containers representing two independent CO 2 tanks, each containing four pipe sections. The containers replicate a ship installation in scale design. The test program and procedures were developed with the operational needs of a CO 2 cargo ship in mind.
It followed the usual process of preparing a ship’s cargo system for receiving, loading, unloading CO 2 and finally preparing for scheduled maintenance.
The project was a collaborative effort between KNCC, Equinor, Horizon Energy, CapeOmega, and DNV classification society, which has already awarded the solution with the Approval in Principle (AiP) .
CLIMIT said that new ways of organizing and implementing CO 2 transport are possible and that this project has shown that:
KNCC said that it has applied for LCO2-EP technology patent and that the solution is now ready for commercial deployment.
“Our test rig confirms that CO 2 transport at elevated pressure (34 to 45 bar) is ready for deployment, ” says Per Lothe , Special Technical Advisor Technology at Knutsen NYK Carbon Carrier.
“Having access to a rig with CO 2 , where we can test equipment and observe adverse events, gives us confidence that the final transport of CO 2 is safe.”
The next phase of the project will be to test new CO 2 equipment, in KNCC’s case corrosion monitoring technology, and to investigate how impurities in the CO 2 can affect the technology.
The company has ambitions to become a major CO 2 transporter in the future. Therefore, having a test rig for verification and crew training is very important in this context.
To remind, in June 2023 Knutsen NYK Carbon Carriers AS teamed up with Pilot Energy Limited , an Australian oil and gas company that is pursuing leveraging its existing infrastructure to develop clean energy projects, to collaborate on an integrated solution for marine transportation and offshore injection of CO2.
The objective under the MoU is for Pilot and KNCC to develop solutions that will enable large-scale industrial emitters to transport via ship, ambient temperature LCO2 and to inject and permanently store CO2 at the Cliff Head CCS Project.
Pilot’s Cliff Head CO2 storage project is an integral component of its Mid West Clean Energy project (MWCEP). It involves the conversion of the operating Cliff Head offshore oil field into a permanent CO2 storage operation capable of storing over 1 mmtpa of CO2 on a continuous basis through 2050 with over 50 million tonnes of potential total storage capacity.
