Salient Direct Ocean Capture

Salient Direct Ocean Capture (DOC) is developing electrochemical technology for carbon dioxide removal (CDR) from seawater. Their approach is designed for scalability and cost. The electrochemical approach uses only electricity and seawater as inputs, avoiding supply chain constraints on plant operations. It also employs the ocean as its carbon dioxide contactor, concentrating it to a hundred times that of the atmosphere by volume. Carbon dioxide removed from seawater can be sequestered through any durable storage mechanism and the effluent seawater returns to the ocean to remove more CO2 from the atmosphere. These efficiencies position Salient Direct Ocean Capture well to meet the projected need for 10-20 gigatons per year of global CDR capacity. Byproducts of the process can generate co-benefits and additional revenue streams to offset the cost of CDR and provide financial stability in nascent carbon removal markets.
