Researchers show economic, environmental and grid-resilience benefits of converting diesel trains to battery-electric

Green Car Congress

At near-future battery prices, battery-electric trains can achieve parity with diesel-electric trains if environmental costs are included or if rail companies can access wholesale electricity prices and achieve 40% use of fast-charging infrastructure. Popovich, N.D., Rajagopal, D., Nat Energy 6, 1017–1025 doi: 10.1038/s41560-021-00915-5.

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.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G.

Sustainable Grid Infrastructure

Blink Charging

Future generations will increasingly rely on the grid to power their vehicles. Consequently, power grid stability and resilience have caught the public’s attention as the demand for electricity and energy-consuming technologies continues to rise. This promotes grid resilience using low-demand hours for EV charging power.
