ClassNK: Onboard CCS practical operation a ‘significant step’ for net-zero emissions

Hailed as a world first by ClassNK, the GHG emissions captured by the onboard carbon capture and storage (OCCS) system on Evergreen’s neopanamax container vessel has been offloaded, verified and recycled.

In April 2024, the OCCS system installed on Evergreen’s neopanamax container vessel. The CO2 captured from the ship’s exhaust emissions have been successfully captured, offloaded to a store facility and recycled.

ClassNK, the Tokyo-based classification society, has confirmed the amount of offloaded CO2 and deducted this amount from this ship;s annual CO2 emissions in a Carbon Intensity Indicator (CII) assessment.

This was completed in a collaborative initiative between the Flag Administration of the Panama Maritime Authority, Evergreen, the Shanghai Marine Diesel Engine Research Institute (SMDERI), and ClassNK.

Each party played an important role in the practical operation:

  • Panama Maritime Authority: Determination of the deduction of captured CO2 amount from OCCS system from annual CO2 emissions in CII assessment
  • Evergreen: Installation/operation of OCCS system, and capture/offloading/ recycling of CO2
  • SMDERI: Development of OCCS system and technical support for the operation
  • ClassNK: Confirmation of compliance with safety requirements in accordance with the Guidelines for Shipboard CO2 Capture and Storage Systems and the amount of offloaded CO2

According to ClassNK, this series of initiatives is just the start of the future practical operations that will be widely conducted and represents a significant step in the maritime industry’s journey to achieving net-zero GHG emissions.
