Abstract : An electrochemical acidification cell was developed and tested as a method for extracting large quantities of CO2 from seawater for use as a feedstock for jet-fuel synthesis at sea. After the technology was successfully demonstrated in the laboratory, it was scaled-up and integrated into a mobile skid design. This report details the results of four separate evaluations (January 22-27, April 25-29, July 11-5, August 28-September 1) of the electrochemical acidification cell performance as a function of pH, current, time, polarity reversal, and CO2 and H2 recovery.
