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).

“Project Volt Gas Volt” proposes long-term financing plan to support widespread implementation of power-to-gas systems

Green Car Congress

Project Volt Gas Volt is based on a long-term financing plan and the use of existing technologies for the large-scale conversion of surplus renewable electricity to methane, with subsequent reuse. If this potential production supplied the Volt Gas Volt plants, the nuclear plants could operate at nearly 100% capacity.
