D4.1.1 & D4.2.1 Life Cycle Assessment of Ship-based Carbon Capture

This report describes identified environmental impacts of the technically feasible ship-based carbon capture (SBCC) systems evaluated in the EverLoNG project on the two case studies: Heerema Marine Contractors’ crane vessel Sleipnir and the liquefied natural gas (LNG) carrier operated by TotalEnergies. Using a Life Cycle Assessment (LCA) approach to evaluate CO2 mitigation, greenhouse gas reduction as well as further environmental impact potentials have been considered on-board the vessels as well as the entire life cycle from fuel supply up to final geological storage of CO2. Only if the additional efforts required for capture, transport, and storage are less than the amount of CO2 captured on-board can this technology truly contribute to maritime decarbonisation.
