Honda Supplies Accord Plug-In Hybrid for Vehicle-to-Grid Demo
Honda has joined in the development of vehicle-to-grid technology with partners including NRG Energy and the University of Delaware. V2G advocates would like to see electric vehicles and their capacious batteries placed at the disposal of utilities when the EVs are idle and electricity demand is high.
The general idea is for EVs in quantity to serve as a collective back-up power reservoir for utilities, with the possibility of EV owners receiving payment for their participation.
V2G, Honda notes, could provide “for more cost-effective ownership of plug-in electric vehicles.”
Research conducted by the University of Delaware is supported by NRG Energy, Inc. “NRG and the University of Delaware, through their eV2g joint venture,” Honda notes, “came online early in 2013 with the world’s first revenue-generating vehicle-to-grid project, demonstrating the controls, regulatory requirements, and market participation rules for selling energy storage from vehicles into the PJM Interconnection Regulation Market” (F&F, April 25).
Offsetting the Disadvantages of Renewables
Honda is supplying an Accord Plug-In Hybrid with added V2G capabilities to the UDel’s Science, Technology and Advanced Research (STAR) Campus “to jointly investigate the potential of this technology to benefit the electrical grid, vehicle owners and society.” The consumer Accord Plug-In Hybrid has a 6.7-kilowatt-hour lithium ion battery.
“Using smart grid technology,” Honda further explains, “the V2G system is able to monitor the status of the grid to determine whether the grid requires additional power sources that can respond rapidly, or the grid requires power demands that can absorb transitional power supply.
“Such a system has the potential to reduce or eliminate the fluctuation of the grid,” Honda says, “which can occur more frequently when renewable energy sources are introduced to the grid. Electric vehicle owners potentially benefit from supporting a more stable power grid, which can lead to reduced utility costs for the vehicle owner.”
OEM Participation ‘Will Help Demonstrate and Refine the Technology’
“This technology has the potential to support both a cleaner and more efficient power grid and a more positive ownership experience for EV customers,” American Honda environmental business development VP Steven Center says in the company’s V2G release. “With V2G technology, a network of PEVs becomes essentially a distributed energy storage system. It makes for an even stronger value equation for plug-in vehicles, with benefits for both the community and the vehicle user.”
“The participation of global automakers like Honda will help demonstrate and refine the technology,” said Willett Kempton, professor in the College of Earth, Ocean, and Environment and Research Director at UDel’s Center for Carbon-Free Power Integration. “The University of Delaware has been developing the technology so that vehicle batteries can be used not only for mobility but also for grid services.
‘A Big Step’
“It is a big step toward a future with widespread availability of the technology to have Honda join our demonstration with their V2G-capable car.”
“As the U.S. adds more intermittent resources to the grid, finding a lower cost energy storage technology that also benefits electric vehicle drivers is a great opportunity,” said NRG executive VP and new businesses president Denise Wilson. “We see this demonstration by Honda as an important step in the development of vehicle to grid technology.”
The demonstration is being conducted in the area served by PJM Interconnection, which controls electricity supply in 13 states and the District of Columbia.
