The dissolved calcium carbonate then reacts with the CO2 in the water to form bicarbonate salts, locking the CO2 away.
Adkins says that with a full-scale reactor, he aims to capture and store about half of a ship’s CO2 emissions.
BAR Technologies/Cargill French company Airseas has developed the Seawing, which it says could help ships cut their carbon emissions by an average of 20%.
A British company called Seabound, for example, makes a device that captures between 25% and 95% of a ship’s CO2 emissions.
“We think that ships are actually going to be able to compete with underground CO2 storage,” he said.
