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.

WMG researchers convert used EV batteries into small off-grid ESS units

Green Car Congress

Researchers at WMG, University of Warwick, have repurposed end-of-life electric vehicle batteries as small energy storage systems (ESS) for off-grid locations in developing countries or isolated communities. We are now looking for support to allow these new units to be further developed and tested in remote or off grid locations.

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

Cars That Think

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. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.

Liebherr converted this massive mining excavator to electric power

Baua Electric

For the first time in the company’s 40-year history, Liebherr have converted one of their R 9400 excavators from a conventional diesel to an electric powertrain. The converted R 9400 can be connected to a constant power source for energy, either directly to the grid or to a large scale BESS.
