SeaO2 is a Dutch Ocean Carbon Removal company developing a technology to remove CO2 from the atmosphere at gigaton-scale, harnessing the potential of the oceans. SeaO2’s solution, Direct Ocean Capture, relies solely on renewable electricity and seawater to extract CO2 from the ocean’s surface and consequently from the atmosphere. The process uses electrochemistry and vacuum to transform the dissolved inorganic carbon in water into gaseous CO2, which is extracted and stored permanently with third party providers.
Compact, fully electric DOC modules that: (1) generate acid/base in-situ via bipolar-membrane stacks; (2) shift carbonate equilibrium to release CO₂ with vacuum stripping; (3) restore pH and return decarbonized water to the surface layer; (4) retrofit into existing water-pumping assets (desalination, aquaculture, thermal plants). No added chemicals, minimal land footprint, MRV-friendly.
