SINTEF Energy Research is leading a pioneering new carbon capture and storage project to enable maritime CO2 emission mitigation.
CO2 emissions from global shipping
As an efficient transport method, maritime shipping has been the backbone of the world economy, accounting for over 75% of the global trade by volume. Consequently, international shipping is responsible for more than 2% of global greenhouse gas emissions (GHG).
To meet the objective of the Paris Agreement, it is critical to significantly reduce shipping GHG emissions. This will have a significant impact on Norway as the 5th largest ship owning country and the marine industry as a whole.
CCS as one of the solutions
Several technologies could be used to reduce these emissions, including the use of zero-carbon fuels such as hydrogen and ammonia, electrification and carbon capture and storage (CCS).
The deployment of zero-carbon fuels will be necessary for the decarbonization of maritime transport. Nevertheless, the low maturity of technology and supporting infrastructure make zero-carbon fuels relevant mainly as long-term solutions.
Due to its already high maturity for onshore applications, on-board CO2 capture systems can play an important role in meeting the shipping emission target before zero-carbon fuels become viable. Considering the long lifespan of existing and planned hydrocarbon-fueled ships, on-board CO2 capture is also expected to be a long-term measure.
Deploying CCS for ships
To develop knowledge and technologies required to achieve such deployment, SINTEF Energy Research is leading a new project called CCShip, which focuses on deploying CCS for ships to enable maritime CO2 emission mitigation.
The main objective of the CCShip project is to develop cost-effective solutions for CCS from ships, as well as understand when CCS can be a more attractive technology than alternative solutions to reduce CO2 emissions from ships.
While solvent-based CO2 capture (also considered as a base case in CCShip) has been shown to be feasible but very likely to be an expensive solution, the CCShip project will also focus on potential of different novel CO2 capture solutions in terms of weight, compactness, integration, efficiency, and cost.
In addition, to maximize opportunities for CO2 capture implementation, CCShip will investigate opportunities for different ship types and transport applications (size, fuel type, voyage distance), as well as consider both new-build and retrofitting of vessels.
In addition to SINTEF Energy Research, the CCShip project gathers other key research and industrial organizations in the fields, namely SINTEF Ocean, NTNU, University of Oslo, Seoul National University, Wärtsilä Moss, Klaveness and Calix Limited. The CCShip project is funded by Wärtsilä Moss, Calix Limited, Klaveness, the Norwegian CCS Centre NCCS, as well as the Norwegian Research Council through the MAROFF program (project no. 320260).
