S Korea’s Daewoo in tie-up to develop ship CCS system

South Korean shipbuilder Daewoo Shipbuilding and Marine Engineering (DSME) is looking to develop an onboard carbon capture and storage (CCS) system with its Greek and US partners, in line with the marine industry's efforts to decarbonise.

DSME has partnered with Greek shipping firm GasLog and maritime classification society the American Bureau of Shipping to develop the system. The technology will capture CO2 from the exhaust gas emitted by vessels and store it onboard before releasing it safely onshore. This can also reduce operating costs for vessels, DSME said on 10 June, without providing further details.

The onboard CCS system is expected to be completed by the first quarter of 2023. The four LNG carriers that GasLog ordered from DSME in 2021 will be delivered with the onboard CCS systems installed from the first half of 2024.

The global maritime sector is required to meet the International Maritime Organisation's (IMO) carbon emissions reduction targets of 40pc by 2030 and 70pc by 2050, compared with 2008 levels. IMO reiterated the need to collaborate to decarbonise earlier this year.

The three firms plan to collaborate on designing an optimal onboard CCS system to be used in LNG carriers that will be built by DSME in the future, as well as to obtain an approval in-principle for the design. DSME has already secured the core technology for the onboard CCS system through joint development with domestic equipment companies, it said.

DSME will conduct a feasibility study on the technology's installation and operations, while GasLog will look into the technical requirements to install and operate the system. ABS will guide the overall rules and regulations related to developing the technology and provide technical advice.
