Abstract

Carbon Capture (CC) technologies are primarily used for onshore projects, such as Shell Canada's Quest in Alberta [1], and only to a limited extent on ships. The lack of current commercial shipping applications of CC emphasises the need for further research and development to reduce maritime CO2 emissions. Green Marine, a project funded by Horizon Europe [2], intends to speed up climate neutrality in water transport by adding emission control solutions to existing fleets. This includes retrofitting guidelines, a software tool catalogue, and showcasing new technologies for carbon capture, energy saving, and reducing fuel consumption. Detailed information on the technologies developed for retrofitting purposes is available in D1.1-Engineering and Preparations for Retrofitting [3] of this project. As part of the project’s further development, this study undertakes a comparative assessment to identify the most promising CC technology for shipboard application based on a comprehensive review of pertinent articles and project reports [4]. The paper first addresses the challenges of implementing shipboard CC technology and then follows with a comparative assessment of different CC technologies to identify promising solutions based on their potential to address these challenges. The results of this overview study will help stakeholders understand the opportunities and challenges of implementing commercially established CC technologies onboard ships. Additionally, the study provides insights for selecting the most promising technologies based on preferences in terms of space, energy requirements, or cost, while addressing other challenges.
