Extraction of Carbon Dioxide from Seawater by an Electrochemical Acidification Cell. Part 1 - Initial Feasibility Studies

Abstract

An electrochemical acidification cell is developed and tested as a method for extracting large quantities of carbon dioxide from seawater for use as a feedstock for jet-fuel synthesis at sea. The electrolytic regeneration of cation exchange resin was demonstrated, allowing simultaneous and continuous ion exchange and regeneration to occur within the cell along with control of the seawater pH. The CO2 in the seawater was readily removed at pHs of less than 6.0. In addition, the cell produced a portion of the hydrogen needed for jet-fuel synthesis without additional energy penalties.
