| Description | ScienceDaily (Dec. 9, 2007) — The price of oil nearly reached $100 a barrel recently, but a new University of Delaware prototype vehicle demonstrates how the cost of the black stuff could become a concern of the past.
A team of UD faculty has created a system that enables vehicles to not only run on electricity alone, but also to generate revenue by storing and providing electricity for utilities. The technology--known as V2G, for vehicle-to-grid--lets electricity flow from the car’s battery to power lines and back.
“When I get home, I’ll charge up and then switch into V2G mode,” said Willett Kempton, UD associate professor of marine policy and a V2G pioneer who began developing the technology more than a decade ago and who is now testing the new prototype vehicle. The UD V2G team includes Kempton as well as Ajay Prasad, professor of mechanical engineering; Suresh Advani, George W. Laird Professor of Mechanical Engineering; and Meryl Gardner, associate professor of business administration, along with several students.
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. |
