Lloyd’s Register has been selected by the Global Centre for Maritime Decarbonisation to conduct a concept study on offloading liquefied CO2 captured onboard ships.
The concept study will address safety and operational considerations surrounding the offloading of LCO2 that has been captured onboard tankers, bulkers and container 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.
GCMD said the outcome of the study can also provide insights for off-loading CO2 as a cargo under currently less-established operating and storage conditions.
Currently, there are no guidelines for offloading captured CO2. The findings of the study will form a basis to enable sea trials in Phase 3 of Project REMARCCABLE (Realising Maritime Carbon Capture to demonstrate the Ability to Lower Emissions), a 500-hour pilot that will be using a non-proprietary amine-based solution, aiming to demonstrate 30% annual CO2 emissions reduction or 1300 kg/hr of CO2, store 375 metric tonnes of LCO2 onboard, and offload LCO2 after 10 days of sailing.
‘We are pleased to be working with Lloyd’s Register on this LCO2 offloading concept study,’ said Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation. ‘The learnings from this study will inform how captured CO2 can be offloaded from various vessel types in general, and enable the sea trials on Stena Impero that are being planned as part of Project REMARCCABLE more specifically.’
Nick Brown, CEO of Lloyd’s Register, added: ‘Conducting this concept study for the Global Centre for Maritime Decarbonisation will deliver greater industry understanding around the safety and operational issues that need addressing for offloading captured LCO2 from vessels.
‘This study, in collaboration with stakeholders from across the maritime value chain, will support the establishment of regulatory and operational guidelines around offloading captured liquid carbon dioxide from vessels, which is crucial to enabling safe adoption of carbon capture technologies on board.
‘It will also offer a timely assessment of the capital expenditure and operating expenditure of the infrastructure needed to offload liquid carbon dioxide from ships thus enabling the industry to make informed decisions for creating this infrastructure.’
The study, which will commence this month, is expected to be completed within nine months.
