Initiated by NMRI, the CO₂ capture testing project was designed to provide validation of results achieved in the lab. It required a proven, full-scale hybrid scrubber system, so the Japanese shipowner associated with the research, who had previously installed PureSOx on another project, arranged with Alfa Laval and the shipyard to include the testing in the vessel’s sea trials.

Carbon capture and storage (CCS) is a potential bridge technology, offering the possibility to extract carbon from emissions until carbon-neutral fuels become more viable. In a full CCS solution, carbon removed from a vessel’s exhaust gas would be stored away to prevent it from ever entering the atmosphere. This project aimed to show that a scrubber could perform the CO₂ capture on board. The modified PureSOx system was able to absorb CO₂ from the auxiliary diesel engines in port, while operating in closed loop.
