To explore the viability of putting carbon capture and storage (CCS) units on existing ships to achieve 2030 CII targets, Bureau Veritas, Wah Kwong, and Shanghai Qiyao Environmental Technology have signed a partnership agreement.

The three parties will concentrate on two categories of bulk carriers operating in the Wah Kwong fleet under a collaboration agreement. In order to assure the safety of the vessels and equipment and that the carbon emission reduction targets are successfully met while the vessels are in operation, Qiyao created a customized design of CCS units for the Wah Kwong fleet, and Bureau Veritas reviewed the plans.

The Qiyao Environmental Technology-created CCS idea has undergone laboratory testing and is currently undergoing continual optimization. The system has so far achieved a total carbon capture rate of over 85%. Different ship types and sizes can be accommodated by the CCS unit. The CCS unit's design approval is currently being looked through.

The absorption unit, separation unit, compression unit, refrigeration unit, and storage unit make up the majority of the CCS system. The primary idea is that the carbon dioxide (CO2) in the absorption unit reacts with the organic amine compound solution to separate it from the remainder of the exhaust stream. After being compressed, filtered, and cooled into liquid carbon dioxide, the extracted carbon dioxide is then stored in a low temperature storage tank after being desorbed from the dissolved carbon dioxide compound solution at a high temperature in the separation tower.

“Carbon capture, utilisation and storage (CCUS) technology captured a total of 40m tons of CO2 in 2021, according to the International Energy Agency (IEA), notably in industrial projects on shore. This makes CCUS one of the options available today that could significantly contribute to achieving carbon neutrality, as well as a promising avenue for reducing emissions from shipping,” said Bureau Veritas Marine & Offshore’s Senior Vice President and Chief Executive Alex Gregg-Smith.
