The successful completion of a carbon capture and storage (CCS) project earlier this year on board the 13,808-TEU Ever Lot has indicated the significant potential of CCS technology is reducing greenhouse gas emissions.

Partners in the project were shipowner Evergreen, flag state Panama Maritime Authority, Shanghai Marine Diesel Engine Research Institute, and ClassNK. The carbon dioxide captured on board the vessel was offloaded to a facility ashore and subsequently recycled.

ClassNK confirmed the amount of carbon dioxide offloaded, deducted it from the ship’s annual emissions, enabling the vessel’s carbon intensity indicator (CII) to be adjusted accordingly under the direction of the Flag Administration of the Panama Maritime Authority.

The responsibilities of the respective parties were clearly set out. Shanghai Marine Diesel Engine Research Institute developed the OCCS system and provided technical support. The container line installed and operated the onboard carbon capture storage (OCCS) system, and subsequently captured, stored, and offloaded the carbon dioxide for recycling.

Meanwhile, the Panama Maritime Authority determined the quantity of captured gas and the annual emissions thereby facilitating the ship’s annual CII calculation. And ClassNK confirmed that all safety requirements were followed in accordance with the Guidelines for Shipboard CO2 Capture and Storage Systems, as well as validating the volume of offloaded gas.

The successful completion of the project is thought to be the first case of its kind in the world and is expected to generate further interest in the technology and lead to a series of similar projects in the months and years to come.
