Taiwanese container shipping company Evergreen Marine Corporation has completed a trial operation of an Ocean Carbon Capture and Storage (OCCS) system on a Neopanamax container vessel.

The 14,000 TEU ship Ever Top, registered in Panama and classed by ClassNK, was retrofitted with the system developed by Qiyao Environmental Protection and installed at Huarun Dadong Dockyard Co. (HRDD) earlier this year. The system uses amine adsorbents to capture CO2. The captured CO2 is then compressed and liquefied for transportation and storage/utilization. The OCCS can provide a maximum 80% net CO2 capture rate and a minimum 99% CO2 purity.

Evergreen has now completed what has been described as a “practical operation” of the OCCS system.

ClassNK announced that in late April, the OCCS system “successfully captured CO₂ from its exhaust gas emissions.” The captured CO₂ was offloaded to a shore facility and was recycled. ClassNK confirmed an amount of the offloaded CO₂, and deducted the amount from the ship’s annual CO₂ emissions in CII assessment under the direction of the Flag Administration of the Panama Maritime Authority.

The classification society revealed to WorldCargo News that the captured CO2 was offloaded at Shanghai Port and that 11.86 tons of CO2 were offloaded.

“This system is still onboard, and we’ll continuously seek the various solutions in order to contribute to global CO2 reduction,” a spokesperson of ClassNK said.

“This series of initiatives anticipates practical operations that may be widely conducted in the future to reduce GHG emissions and is the first case in the world. This is a significant step for the maritime industry to achieve Net-zero GHG emissions,” ClassNK pointed out.

Onboard carbon capture systems have emerged as a promising technology that can help existing vessels curb their emissions and extend their service life by cleaning engine exhaust. Nevertheless, one of the key challenges to the wider adoption of the technology has been the lack of shoreside infrastructure for the offloading of CO2.
