Non-condensable gas exchange characteristics in seawater and fresh water are compared and contrasted. The higher rate of exchange observed for these gases in seawater is incorporated in suggested Open-Cycle OTEC changes that will reduce overall costs, increase condenser efficiency and prevent CO2 discharges to the atmosphere as well as de-oxygenated water discharges to the ocean.
