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%.

First Supercritical CO2 Circuit Breaker Debuts

Cars That Think

Such equipment is scattered widely throughout power grids as a way to stop the flow of electrical current in an emergency. Hundreds of thousands of circuit breakers dot power grids globally, and nearly all of the high voltage ones are insulated with SF 6. locationa gold standard certification facility.

Roskill: CO2 emissions from lithium production set to triple by 2025

Green Car Congress

The high emissions intensity of refining concentrate to lithium carbonate or hydroxide, in part driven by China’s power grid mix and reliance of coal. The low emissions output from mining equipment and on-site vehicles, despite their comparatively high energy intensity.

EIA: California drought will decrease hydropower, increase natural gas use and CO2 emissions

Green Car Congress

California has a diverse electricity fuel mix and is highly interconnected with the regional electric grid, but our study shows that a significant decrease in hydropower generation this summer could lead to higher electricity prices, among other effects.

Mercedes-Benz to source CO2-free electricity in Germany from solar, wind and hydropower from 2022 onwards

Green Car Congress

Generation of green electricity is synchronized to follow patterns of consumption so that a supply from the grid with green electricity can be guaranteed on a quarter hourly basis. In many previous green power contracts, feed-in to the grid takes place purely on an annual balance basis.
