World’s First Carbon-Capturing Cargo Ship Sets Sail, Promises Green Construction Boom

A revolutionary cargo ship equipped with Seabound’s carbon capture system has set sail, turning its CO₂ emissions into limestone used for green cement production.

This marks the world’s first commercial carbon capture technology implemented on a vessel, installed on the UBC Cork, a cement carrier owned by Germany’s Hartmann Group.

How does Seabound’s onboard carbon capture system work?

The system traps exhaust gases from the ship’s diesel engines and directs them into a high-pressure chamber filled with calcium hydroxide pebbles.

Within this chamber, carbon dioxide reacts with the pebbles to form calcium carbonate, known as limestone, which is stored on board for offloading and use in cement production.

Did you know?
Seabound’s system can capture up to 95% of CO₂ and 98% of sulphur emissions from a ship’s exhaust, significantly reducing pollution at sea.

What impact could this technology have on the shipping industry?

Seabound’s modular system can capture up to 95% of CO₂ and 98% of sulfur emissions, offering shipping companies an immediate way to reduce pollution without waiting for alternative fuels.

Designed to retrofit existing vessels, this innovation promises rapid deployment across fleets globally, helping curb the sector’s 3% share of global emissions.

Seabound transforms ship emissions into key cement ingredients

The limestone produced is delivered to Heidelberg Materials’ cement plant in Brevik, Norway, where it integrates carbon captured at sea into onshore green construction materials.

This closed carbon loop helps reduce the environmental footprint of cement, one of the most carbon-intensive building materials worldwide.

This innovation offers an interim step toward cleaner shipping

Although cleaner fuels like hydrogen and ammonia remain the ultimate goal, their widespread adoption is decades away due to new ship requirements.

Seabound’s carbon capture technology offers a critical bridge solution, immediately lowering emissions while alternative propulsion innovations mature.

Seabound's technology, aiming to capture 100 million tons of CO₂ annually by 2040, is poised to revolutionize maritime sustainability.
