Deuterium from seawater
WebMar 1, 1978 · Since the deuterium concentration in seawater is as low as 158 ppm, almost all of the deuterium exists in the form of HDO, instead of DaO (2). Therefore, one must notice the vapor-liquid equilibrium of only HDO, or the relative volatility of HDO and HzO. Equilibrium concentration ofHaO, HDO and DaO is shown in Fig. 3. WebDeuterium is produced from seawater. It is cheap: Currently it costs about $1/gram. Is deuterium the fuel of the future? Deuterium is used in a number of conventional nuclear reactors in the form of heavy water (D 2 O), and it will probably also be used as fuel in fusion reactors in the future.
