Shipping has a pollution problem, but one company has a solution that does more than just eliminate a boat\u2019s carbon dioxide.<\/p>\n
London-based Seabound<\/a> has developed a carbon capture system that transforms CO2<\/sub> from the engine into limestone, a key ingredient in cement.<\/p>\n Fittingly, the company has installed it aboard the UBC Cork<\/em>, a cement carrier currently sailing through the Mediterranean Sea. When the ship docks in Norway, the limestone created from the voyage will be offloaded and used to make more cement at Heidelberg Materials<\/a>\u2019 net-zero plant in Brevik. (The name Heidelberg may ring a bell \u2014\u00a0earlier this year, it inked a deal to deploy more than 100 autonomous trucks from former Google exec Anthony Levandowski\u2019s startup Pronto<\/a>.)<\/p>\n Both maritime shipping and cement are highly polluting industries, representing about 3% and 8% of global carbon emissions, respectively.\u00a0<\/p>\n Their emissions are challenging to address, too. For shipping, batteries are not currently energy-dense enough to enable the sorts of voyages many vessels undertake. And the chemical reaction that forms Portland cement, the most widely used type, releases carbon dioxide, to say nothing of the fossil fuels that typically drive the process.<\/p>\n There\u2019s some urgency for maritime shipping to rein in its pollution: The International Maritime Organization (IMO), which regulates the global shipping industry, will require owners to trim greenhouse gas emissions<\/a> from their fleets by 30% over the next decade, rising to 65% by 2040.<\/p>\n
