Sandia team develops GaN diode that is significant step toward protecting grid from EMPs

Green Car Congress

Scientists from Sandia National Laboratories have developed a new gallium-nitride (GaN) diode that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts—a significant step towards protecting the nation’s electric grid from an electromagnetic pulse (EMP). —Bob Kaplar.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.
