- | After spending years traveling the world while working in the United States military, Christopher Boris dreamed of one day moving overseas | + | The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently. |
- | But the retired veteran, who grew up in New Jersey but was based in Maryland at the time, ended up relocating earlier than he’d intended after struggling | + | The practice is not free of controversy, |
- | “I really couldn’t afford my mortgage payments | + | Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions. |

- | In the summer of 2024, Boris and his wife Maria Jesus, originally from Bolivia, left the US to start a new life in Brazil. | + | |
- | “I could not afford | + | “The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team. |

+ | SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute | ||

To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says. |
