The Global Centre for Maritime Decarbonisation (GCMD) and the research centre Shanghai Qiyao Environmental Technology, affiliated with the China State Shipbuilding Corporation, with support from the Shanghai Marine Diesel Engine Research Institute.<\/p>\n
GCMD and Shanghai Qiyao Environmental Technology have successfully completed the world\u2019s first ship-to-ship (STS) transfer of CO\u2082 using an Onboard Carbon Capture and Storage (OCCS) system. This system enables vessels to capture and store CO\u2082 emissions during navigation.<\/p>\n
In this pilot, 25.44 metric tons of CO\u2082 were transferred from the vessel MV Ever Top<\/em> to the receiving ship Dejin 26<\/em>. The captured CO\u2082 was then offloaded at the port of Zhoushan (Zhejiang province, China) into a tanker truck and later transported to a low-carbon calcium carbonate production facility in China\u2019s Inner Mongolia region.<\/p>\n The STS transfer of CO\u2082 is a major breakthrough, as it allows carbon capture to occur offshore without the need to dock \u2014 a critical feature for large vessels that cannot access smaller ports. This innovation enables the captured CO\u2082 to be delivered to buyers who can use it to produce materials like methanol, plastics, or cement, or for agricultural purposes in greenhouses, where CO\u2082 is used to stimulate photosynthesis, promoting faster and more robust plant growth and potentially enhancing product quality.<\/p>\n The main goal of this innovative project is to support the decarbonisation of the maritime industry, which currently accounts for about 3% of global greenhouse gas emissions. Through OCCS, the aim is to implement a viable solution for complying with stricter emissions regulations by repurposing captured CO\u2082 as a raw material in various industrial processes.<\/p>\n The innovation of STS CO\u2082 transfer is a key step in proving the large-scale viability of this system, reducing operational costs and expanding the circular economy applications of captured CO\u2082. The Ever Top<\/em> vessel, which captures over 80% of its CO\u2082 emissions with 99.9% efficiency, stands as a clear demonstration of how this technology can be integrated into maritime decarbonisation strategies and contribute to the advancement of a more sustainable blue economy.<\/p>\n July 25, 2025<\/p>\nProject objectives<\/h4>\n
