Ocean Acidification Effects and Responses

The maritime industry has set clear objectives towards reducing greenhouse gas emissions in the coming decades. Ship based carbon capture (SBCC) could play a large role in reducing these emissions on the short term. This study gives an update on the work that has been conducted towards carbon capture and storage on LNG fuelled vessels. This is done by discussing the results of the DerisCO2 project where CO2 capture on the LNG fuelled Sleipnir vessel from Heerema Marine Contractors is analysed. One of the main advantages of SBCC is the heat integration of the vessel and the capture plant, which drastically decreases the heat and electricity demand of the capture plant and the total capture costs become fully CAPEX dominated. Taking into account the operational profile of the Sleipnir vessel, a conceptual design is proposed which consists of four absorbers and a single desorber, which is able to capture 72.5% of the CO2 emissions over the whole sailing profile. The total cost of CO2 capture, liquefaction and on-board storage for the Sleipnir vessel is estimated at 115 €/ton CO2, where the variable OPEX is estimated at 5.7% of the total costs. Lastly, the results of the tilting table experiments in the DerisCO2 project are discussed, where the effect of vessel tilting at sea on CO2 absorption is analysed. It is shown that static tilting causes a reduction in the overall mass transfer rate of CO2 absorption, but upon continuous tilting, the mass transfer rate is similar compared to static tests, which sets the expectation that vessel tilting at sea will have no negative effect on CO2 absorption.
