AN ELECTRIC CAR THAT ALSO PROVIDES peak power for utilities: “When the car is in the V2G setting, the battery’s charge goes up or down depending on the needs of the grid operator, which sometimes must store surplus power and other times requires extra power to respond to surges in usage. The ability of the V2G car’s battery to act like a sponge provides a solution for utilities, which pay millions to generating stations that help balance the grid. Kempton estimates the value for utilities could be up to $4,000 a year for the service, part of which could be paid to drivers. The technology will work on a large scale, he said, because on average 95 percent of all cars are parked at any given time.” Sounds kind of cool.
