Meet the cement transport ship that makes cement ingredients while sailing


London-based Seabound has developed a carbon capture system that transforms CO2 from a ship's engine into limestone, which Heidelberg Materials will use to make cement.

(The name Heidelberg may ring a bell — earlier this year, it inked a deal to deploy more than 100 autonomous trucks from former Google exec Anthony Levandowski’s startup Pronto.) 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. Seabound is proposing a retrofit that would leave existing internal combustion engines intact, adding a carbon capture system that would tap into their exhaust pipes.
