SeaCURE: Sea Carbon Unlocking and REmoval

Led by the University of Exeter together with the Plymouth Marine Laboratory, Brunel University London and TP Group.

 

Direct removal of CO2 from air is hampered by its very low concentration. The concentration of CO2 in seawater is however approximately 150 times higher. SeaCURE technology will process seawater to temporarily make it more acidic, which helps to get the carbon dioxide to ‘bubble out’. The technology will then trap that CO2 and concentrate it to form a near-pure stream of gas to be compressed and stored. The carbon dioxide-depleted water will then be released back to the ocean, where it will take up carbon dioxide from the air. Combining, optimising, and enhancing existing technology, this project will design a pilot plant and a pathway to deliver carbon dioxide removal at the megatonne scale, offering a key solution to perhaps the planets most pressing problem.


The project is funded by BEIS as part of Phase 1 of the Direct air capture and greenhouse gas removal programme.
