Bidirectional Charging Management (BCM) research project gets green light; tying in renewables

Green Car Congress

Not only will electric vehicles with bidirectional charging capability be able to draw electrical power for their high-voltage battery when plugged into a compatible charging station or wallbox, they will also have the ability to reverse the process and feed energy back into the power grid.

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.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. In light of the sheer scale of the hydrogen challenge, several questions demand close consideration.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

A team of scientists at the University of Cambridge has reported the light-driven photoreforming of cellulose, hemicellulose and lignin to H 2 using semiconducting cadmium sulfide quantum dots in alkaline aqueous solution. CdS is an inexpensive, visible-light-absorbing photocatalyst with a bulk electronic bandgap of around 2.4

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. As in Palo Alto, it will likely be blown transformers or constantly flickering lights that signal there is an EV charging-load issue. This situation is not true universally.
