Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.

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.

A Heat Pump Water Heater Will Save All the Electricity You’ll Need to Power Your Electric Vehicle

CleanTechnica EVs

A common critique of the “electrify everything” movement is that it will be near impossible to produce enough clean electricity to replace the fossil fuels used in buildings and transportation and make sure the grid is strong enough to deliver it. While this concern is valid, there is an important card humanity has in its […]

Lawrence Livermore publishes state-by-state energy/water Sankey diagrams

Green Car Congress

For the first time, Lawrence Livermore National Laboratory (LLNL) has published state-by-state energy and water Sankey diagrams in one location so that analysts and policymakers can find all the information they need in one place. General location of energy and water categories. Energy and water generally “flows” from left to right.

Xcel Energy, INL to use nuclear energy for clean hydrogen production; HTSE

Green Car Congress

Minneapolis-based Xcel Energy will work with Idaho National Laboratory to demonstrate a system that uses a nuclear plant’s steam and electricity to split water. It builds on a project launched last year to demonstrate how hydrogen production facilities could be installed at operating nuclear power plants. Earlier post.)
