DNV and partners launch CETO joint industry project (JIP) to develop low pressure solutions for CO2 ship transport
Equinor, Shell, TotalEnergies, Gassco and classification society DNV announced the kick-off of a new JIP to develop low-pressure solutions for the transportation of CO2 by ships, according to DNV's release.
The CETO (CO2 Efficient Transport via Ocean) JIP will carry out the technology qualification of a low-pressure ship design and identify solutions to scale CO2 transportation volume, while reducing the associated risks, to support the development of opportunities in CCS. CETO is funded by the project partners and GASSNOVA through the CLIMIT programme and is expected to be completed in 2023.
Carbon capture and storage (CCS) will be a key technology if the world is to meet the goals of the Paris and Glasgow agreements. Although the technologies and the industry are very much still emerging, a possible challenge is connecting capture sources to facilities for use or storage sites, especially where pipelines are not an option. As a result, CO2 transport ship technology will be needed if large quantities are to be safely transported at costs that are commercially viable. Today, most transport of CO2 via ship takes place at small scale and at medium pressure (15 bar at -28ºC), limiting the possibilities of scaling up to meet future growth in CCS.
To transport CO2 safely and efficiently at industrial scale by ship, low pressure transport systems (approx. 7 bar at -49ºC) are a potential solution, as this enables much larger tank volumes, cargo capacities and therefore reduced transportation costs. However, the industry currently has little practical experience with the transport of liquid CO2 (LCO2) under these conditions.
The JIP looks to build experience in low pressure transport and fill a vital knowledge gap, by examining the fundamentals of a low-pressure CO2 transport chain, including:
• A LCO2 ship design, with low pressure tank and cargo handling system
• Material choice and testing
• Medium scale testing and simulation of cargo handling
• Conditioning and liquefaction
• Testing LCO2 behaviour at low pressure
The CETO JIP is named after Ceto, who is a primordial sea goddess in Greek mythology, and builds on an earlier project carried out by the partners that investigated the technology gaps and identified qualification activities to demonstrate that the technologies offer the required levels of operational safety and reliability.
