Researchers demonstrate concept desalination battery

Green Car Congress

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.

DOE Awarding $620M for Smart Grid Demonstration and Energy Storage Projects

Green Car Congress

These 32 demonstration projects, which include large-scale energy storage, smart meters, distribution and transmission system monitoring devices, plug-in vehicles, and a range of other smart technologies, will act as models for deploying integrated Smart Grid systems on a broader scale. Improved energy storage technologies will allow for expanded integration of renewable energy resources like wind and photovoltaic systems and will improve frequency regulation and peak energy management.
