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.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Cars That Think

Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses. Debates over the feasibility and value of such vehicle-to-grid technology go back decades.

Daimler showcasing eCitaro fuel cell bus at GPTS in June

Green Car Congress

At Global Public Transport Summit (GPTS) 2023 from 4 to 7 June 2023, Daimler Buses will be showcasing the first series-production electric bus with fuel cell as a range extender: the Mercedes-Benz eCitaro fuel cell. Before the launch of series production in June, the eCitaro had to pass numerous endurance and functional tests.

A wood-burning EV charger? – Charged EVs

Baua Electric

The BioCharger is designed to provide off-grid power from vegetative waste. Then, it converts the residual heat energy into electric energy and stores it in a connected Battery Storage Module. The accompanying charging mechanism allows the stored energy to be used for off-grid EV and machinery charging.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

Electricity production in Germany, 2018. Unfortunately, due to our grid situation, electric cars are still too early for this strategic goal in the sense of German climate protection efforts. The researchers carried out their calculations based on a Mercedes-Benz C 220 d diesel and the new Tesla Model 3. —Professor Buchal.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

Researchers from the US Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a new lithium/polysulfide (Li/PS) semi-liquid (flow) battery for large-scale energy storage, with lithium polysulfide (Li 2 S 8 ) in ether solvent as a catholyte and metallic lithium as an anode.
