A giant cargo ship is trapping carbon from its exhaust and turning it into cement for use in onshore construction.<\/span><\/p>\n

The technology, developed by UK startup Seabound, is billed as the world\u2019s first commercial carbon capture system for boats. It\u2019s installed on the UBC Cork, a cement carrier owned by Germany\u2019s Hartmann Group.<\/span><\/p>\n

\u201cThese are the systems we intend to scale across hundreds, and eventually thousands, of vessels,\u201d Alisha Frediksson, Seabound\u2019s CEO and co-founder, told TNW. \u201cWe\u2019re therefore very excited to get them out into the world \u2014 to gather valuable data, optimise future iterations, and most importantly, to show the industry that onboard carbon capture is no longer just a concept.\u201d<\/span><\/p>\n

Seabound\u2019s carbon capture equipment traps the exhaust gas produced by the vessel\u2019s huge diesel engines and funnels it into a big, high-pressure chamber filled with calcium hydroxide pebbles.\u00a0<\/span><\/p>\n

The CO2 in the exhaust gas reacts with the pebbles and transforms into calcium carbonate \u2014 also known as limestone, the key ingredient in cement. That limestone is stored onboard and will be offloaded in Norway, where it will be delivered to Heidelberg Materials\u2019 cement plant in Brevik. There, it will be used to produce greener concrete on an industrial scale as part of Heidelberg\u2019s <\/span>existing<\/span><\/a> carbon capture facility.\u00a0<\/span><\/p>\n

Seabound claims its system can capture up to 95% of CO\u2082 and 98% of sulphur emissions from a ship\u2019s exhaust. Its modular design allows it to be bolted onto existing vessels with minimal changes. <\/span>It offers the shipping industry a way to cut emissions immediately \u2014 but it can\u2019t replace the long-term need for cleaner fuels to replace diesel altogether.<\/span><\/p>\n

A step toward cleaner voyages<\/b><\/h2>\n

Shipping accounts for nearly <\/span>3% of global emissions<\/span><\/a> but is notoriously hard to decarbonise. Current<\/span> battery technology<\/span><\/a> simply cannot provide enormous cargo vessels with enough power to cover long distances. Nuclear propulsion has also been considered, but comes with<\/span> risks<\/span><\/a> and remains controversial.\u00a0<\/span><\/p>\n

Most experts agree that the best bet is alternative, zero-emission fuels, such as hydrogen and ammonia. But these are still in the early stages of development and require the building of entirely new ships.<\/span><\/p>\n

Seabound\u2019s tech<\/a>, then, could provide an interim solution to curb emissions from shipping, while we wait for other, more permanent fixes to be developed.\u00a0<\/span><\/p>\n

\u201cAlternative fuels for ships are at least 10 to 20 years away, but we need to start decarbonising today,\u201d Frediksson <\/span>previously told TNW<\/span><\/a>.\u00a0\u00a0<\/span><\/p>\n

Seabound has already trialled its technology with shipping firms Hapag-Lloyd and Lomar Shipping. It\u2019s now looking to scale up its systems, targeting 100 million tonnes of CO\u2082 captured per year by 2040 \u2014 10% of the shipping sector\u2019s total emissions.<\/span><\/p>\n

This latest project, its first commercial endeavour, was co-funded by the EU\u2019s Eurostars startup<\/a> programme and backed by the Cyprus Marine and Maritime Institute.<\/span><\/p>\n<\/p><\/div>\n
