Why It Matters

eDOC addresses the global challenge of rising atmospheric CO2 and the increasing CO2 saturation of the ocean, offering a pathway for massive-scale carbon removal. In a mainstream future, fleets of offshore platforms or coastal facilities could act as carbon removal factories, not only reducing atmospheric CO2 but also helping to reverse ocean acidification. Maritime engineering firms, electrochemical technology developers, and oceanographic research institutions are poised to be major winners, while some land-based DAC developers might face competition. Key barriers include the high energy consumption of the electrochemical processes, the significant scale-up of ocean infrastructure, potential localized impacts on marine ecosystems, and high capital costs. Significant scaling is projected for the 2040s, with the US, EU, and various private startups leading the development. A crucial second-order consequence is the need for new international governance frameworks and monitoring protocols for large-scale ocean carbon removal, potentially sparking debates over the 'ownership' or stewardship of ocean carbon capacity.
