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.

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

The goal is to make the testbed available to outside research teams and industry by 2025. The major driver for the project is the need to decarbonize the electrical grid, protect it from cybersecurity attacks and make it more resilient. We will be replicating the entire California power grid on one campus.
