LCO2 offloading concept study

The Global Centre for Maritime Decarbonisation is pleased to award its concept study on offloading liquefied CO2 (LCO2) captured onboard ships to Lloyd's Register, supported by their partner Arup.

Ammonia bunkering study: Text

This study will address safety and operational considerations surrounding offloading of LCO2 that has been captured tankers, bulkers and containers liners, including articulating the temperatures and pressures under which this process would optimally take place and the different receptacles to be used for this purpose.

IMO target

In 2018, the International Maritime Organization (IMO) declared its ambition to halve the total annual GHG emissions from international shipping by 2050 compared to 2008 levels. To meet this target, the transition to low-/zero-carbon fuels and technologies is necessary.

The case for offloading of CO2 

To advance the end-to-end implementation of shipboard carbon capture (SBCC) systems, GCMD issued an Invitation-for-Proposals (IFP) on 2nd December 2022, to articulate the concept design for the offloading of shipboard captured CO2 during port calls. The study will also support the establishment of regulatory and operational guidelines that will govern future piloting and demonstration projects related to SBCC.

Ammonia bunkering study: Programs

Develop concepts to safely + accurately offload shipboard captured CO2

Assess the readiness of current infrastructure for LCO2 offloading

Generate CAPEX + OPEX models

for LCO2 offloading infrastructure, buildout + operation costs

Review + identify gaps in custody transfer, competency standards + regulatory approval

Review policy + regulation regimes

+ identify those that allow offloading of shipboard captured CO2

Validate & finalise findings with industry stakeholders
