Det Norske Veritas (DNV) and Process Systems Enterprise (PSE ), a provider of advanced process modelling technology, have claimed that maritime carbon capture and storage (CCS) is feasible and it can reduce emissions by 65%.

The feasibility of the onboard CCS system has been announced following a joint project by DNV and PSE, which has developed a concept design for on-board chemical CO2 capture.

The system uses chemical absorption to separate CO2 from flue gases that are compressed in a liquefaction unit and temporarily stored in two tanks while the ship is in transit to discharge them into a transmission and storage facility at a port.

According to DNV, the new system could reduce CO2 emissions for a very large crude carrier (VLCC) by over 70,000 tonnes per year, transforming ship emissions into a tradable product.

DNV’s head of research & innovation for Greece Dr. Nikolaos Kakalis said there will be increased demand for new solutions towards higher efficiency and greener operations to meet strict environmental regulations and complex market conditions.

"Our R&D activities, such as the carbon capture initiative, which is completely new in the field of maritime transportation, pave the future towards next-generation solutions for achieving more energy-efficient, environmentally friendly and sustainable maritime transportation," Kakalis said.

PSE managing director Professor Costas Pantelides said: "Applying a model-based engineering approach has been key to exploring the process decision space rapidly and effectively, and developing technically feasible and economically viable solutions."

Current maritime CO2 emissions are estimated to be more than a billion tonnes a year, or 3% of total emissions, and they are expected to reach 2-3 billion tonnes by 2050.

Under the Eurostars initiative, the UK’s Technology Strategy Board and The Research Council of Norway provided funds for the maritime CCS project.
