New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. Compared with a seasonal battery, this new design is especially adept at short- to medium-term grid energy storage over 12 to 24 hours.

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. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

CEC determines Diablo Canyon needed to support grid reliability

Green Car Congress

The determination is based on data showing California risks energy supply shortfalls during extreme weather events. The nuclear power plant supplies about 17% of California’s zero-carbon electricity and 9% of total electricity. This includes extreme heat and wildfires that threaten the grid with growing frequency and intensity.
