A giant cargo ship uses a carbon capture system to transform exhaust emissions into cement for construction. Developed by UK startup Seabound, the technology is installed on the UBC Cork, a cement carrier. The system captures exhaust gas, funneling it into a chamber with calcium hydroxide pebbles, which react to form calcium carbonate. This limestone is offloaded in Norway for use in greener concrete production. Seabound claims the system captures up to 95% of CO₂ and aims to scale across many vessels, showing the practical viability of onboard carbon capture.
Seabound's system captures CO2 and transforms it into calcium carbonate, the key ingredient in cement, by using a high-pressure chamber filled with calcium hydroxide pebbles.
The technology captures up to 95% of CO₂ and 98% of sulphur emissions from a ship's exhaust, offering an immediate way to cut emissions in the shipping industry.
Seabound aims to scale its carbon capture technology across hundreds, eventually thousands, of vessels, showcasing the feasibility of onboard carbon capture.
The limestone produced from captured CO2 will be offloaded in Norway for use in producing greener concrete at Heidelberg Materials' cement plant.
