IMO Support Secured for Onboard CO2 Mineralisation
Shanghai Qiyao Technology Group has secured in-principle support at the International Maritime Organization (IMO) for treating onboard carbon mineralisation as permanent CO2 storage. This development comes after the company submitted two joint proposals to the IMO’s working group during MEPC 84, which were welcomed by the organisation.
The proposals argue that captured CO2 can be converted through mineralisation into stable carbonates, including calcium carbonate, creating permanent storage without carbon leakage. Qiyao is positioning this process as an alternative to conventional onboard carbon capture and storage, which relies on geological storage and faces high costs and limited reception infrastructure.
“We see this IMO attention as an important step,” said the head of Qiyao’s OCCS team. “Closing the loop from shipboard capture to onshore mineralisation can make carbon accounting more practical and economically attractive for the industry.”
Technical and Environmental Case
Document MEPC 84/7/18 sets out the technical and environmental case for treating mineralisation as equivalent to permanent sequestration. The document draws on Qiyao’s demonstration project, using full-chain data covering onboard capture, ship-to-ship liquid CO2 transfer, land transport, and final mineralisation.
The company has fitted a full-scale OCCS system on a 14,000-TEU container vessel and completed what it calls the world’s first ship-to-ship transfer of liquid CO2 for onshore mineralisation. Qiyao is working with global partners on integrated solutions for the green upgrading and transition of global shipping.
Company Background
Shanghai Qiyao Technology Group Co., Ltd. is a company focused on shipping-related energy and environmental technologies. Its stated business areas cover green fuel power systems, integrated energy efficiency solutions, marine environmental protection equipment, core LNG products, and smart marine devices for oceangoing vessels and specialized ship types.
The company’s commitment to reducing the environmental impact of shipping is reflected in its development of innovative technologies and solutions for the industry. The success of Qiyao’s proposals at the IMO marks an important step forward in this effort, as it paves the way for the widespread adoption of onboard CO2 mineralisation as a viable carbon capture and storage solution.
