Seatrium Fits CO2 Capture System Onboard Mol’s Tanker

Wedoany.com Report-Mar 5, Singapore-headquartered offshore, marine, and energy solutions provider Seatrium has completed a carbon capture and storage (CCS) retrofit project for Japanese shipping company Mitsui O.S.K. Lines (MOL), installing an onboard CO2 capture system on an LR1 product tanker.

Seatrium announced the delivery on Nexus Victoria, the first Japanese vessel to have a commercially installed CO2 capture system, via social media on March 4, 2025.

The retrofit project, which kicked off in December 2024, included planning, design, detailed engineering, procuring, upgrading electrical and automation systems, and integrating Value Maritime’s Filtree system, an onboard CO2 capture system with a SOx scrubber.

Seatrium described the delivery as “a notable step forward” in the shipping industry’s efforts to reduce carbon emissions and enhance sustainability.

To remind, MOL revealed plans to fit Value Maritime’s 15 MW next-generation exhaust gas cleaning system (EGCS) Filtree with its additional carbon capture unit on the 75,000 dwt Nexus Victoria in April 2024.

As explained, the Filtree system is based on a technology that filters sulfur, CO2 and ultra-fine particulate matter from the tankers’ exhaust stream.

The plug-and-play system installed on the MOL product tanker captures CO2 from the vessel’s exhaust and stores it in tanks onboard. This is then discharged onshore where it can be used, for example, in the sustainable cultivation of greenhouse crops, methanol plants, and even the food industry.

The Filtree system has a scrubber function that removes 99% of sulfur oxides and particulate matter (PM) contained in exhaust gases and a CCS function that separates and recovers up to 10% of CO2 from the exhaust emissions, according to Value Maritime.

As understood, the retrofit project is part of MOL Group’s environmental strategy to achieve net-zero greenhouse gas (GHG) emissions by 2050 and a noteworthy initiative to promote decarbonization of existing vessels which are difficult to convert to next-generation fuels.
