End-to-end shipboard carbon capture initiative launched

The Global Centre for Maritime Decarbonisation (GCMD), the Oil and Gas Climate Initiative (OGCI) and Stena Bulk launched the project together with Alfa Laval, the ABS, Deltamarin and TNO.
The project has been named REMARCCABLE (Realising Maritime Carbon Capture to demonstrate the Ability to Lower Emissions) and will roll out across three phases over two years.

Phase one – conceptual design and front-end engineering design study for completion Q1 2023.
Phase two – engineering, procurement and construction of a prototype shipboard carbon capture system.
Phase three – integration of the carbon capture system onboard MR tanker Stena Impero and conducting sea trials of over 500 hours of carbon capture and offloading of liquid CO2 along a 10-day deep-sea route to an already identified CO2 consumer.

Progress from one phase to the next will depend on a review of the previous phase and support from the various partners.
The initiative aims to develop onboard capture and storage of CO2 as well as the offloading of that captured CO2 at port. The target for the technology is around one tonne of carbon captured per hour, or 30% absolute CO2 emissions. The project also aims to establish a pathway to bring down CO2 capture costs to EUR150 per tonne or below.
The companies said the project will use non-proprietary technology, allowing the results to be shared publicly. The partners said an MR tanker was chosen as similarly-sized vessels represent around 17% of total shipping CO2 emissions.
Carbon capture is a means of recovering carbon emissions to meet decarbonisation targets while development of low- and zero-carbon fuels and the related infrastructure continues. “Projections indicate that 85% of the fuel mix for two-stroke engines will remain fossil-fuel based by 2030 and 34% by 2050. Shipboard carbon capture can help reduce GHG emissions of current vessels, with the possibility of recycling captured CO2 to produce alternative fuels,” said the partners.
Erik Hånell, CEO of Stena Bulk, said: “We are proud to collaborate with GCMD, OGCI, and especially our customers, to demonstrate shipboard carbon capture on one of our vessels. Exploring this technology is crucial to understanding the role it could play in facilitating our industry’s decarbonisation.”
Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation, said: “GCMD views shipboard carbon capture as one of the mid-term solutions needed to help the maritime sector to decarbonise. The open sourcing of project REMARCCABLE, piloting under real-world conditions and delivering end-to-end solutions, is in line with GCMD’s goals of lowering the barriers for adoption so international shipping can meet or exceed the International Maritime Organization’s (IMO) GHG emissions reduction targets for 2030 and 2050.”
