Stashing CO₂ in the sea

Close to the eastern tip of Canada, in Nova Scotia’s picturesque Halifax harbor, a local firm has joined the fight against climate change. There, Planetary Technologies has figured out how to turn the cooling water of a power plant into a tool against global warming, by enhancing its capacity to absorb carbon dioxide from the air.
Founded in 2019, Planetary Technologies is at the vanguard of an emerging worldwide effort to squirrel away industrial carbon emissions in the ocean. It’s still early.
