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. In comparison, the energy density for lithium-ion batteries used in commercial electronics and electric vehicles is around 170–250 Wh/kg.

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%.

IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

IPG’s project will demonstrate the role of Flameless Ceramic Turbine technology in bringing EV charging to high-use and remote locations through clean, cheap, grid-independent power generation. But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable.
