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.

Southern California Edison to buy 261 MW of energy storage projects; largest grid-connected storage purchase in US

Green Car Congress

The new contracts result from a plan recommended by SCE in response to state forecasts of local reliability needs due to the closure of the San Onofre Nuclear Generating Station and anticipated retirement of older, natural gas generation plants along the Southern California coastline that rely on ocean water for their cooling needs.
