Researchers demonstrate concept desalination battery
Green Car Congress
JANUARY 30, 2012
A team from Stanford University and Ruhr-Universität Bochum have demonstrated the novel concept of a “desalination battery” that uses an electrical energy input to extract sodium and chloride ions from seawater and to generate fresh water. A four-step charge/discharge process allows the electrodes to separate seawater into fresh water and brine streams: Fully charged electrodes, which do not contain mobile sodium or chloride ions when charged, are immersed in seawater.
