How UD is Making Electric Vehicles Good for Your Pockets and the Earth

On Friday, March 4th, Green Liaisons hosted Dr. Willett Kempton, UD Professor in the School of Marine Science and Policy and Research Director at the Center for Carbon-Free Power Integration, for our first lunch of the semester.

He shared with us the latest news about the vehicle-to-grid (V2G) technology that he helped to spearhead.

V2G technology is an innovation of renewable energy research that enables electric vehicles to communicate with the electric grid in order to recycle stored battery power.

Beginning with local situation of electric vehicles (EVs), Dr. Kempton mapped out the current locations of electric vehicle charging stations in Delaware in order to demonstrate the benefit of how deliberate public planning can benefit the electric-vehicle driver and how that planning is already being instituted in this state.

He also described for us the benefits of transitioning to EVs. The environmental benefits are certainly known, but what Dr. Kempton stressed were the advantages earned by the entire grid system and by the EV driver when V2G technology is implemented, as this enables the grid to rely on a more efficient and quick-responding power source and it enables the driver to earn a profit from the energy they are sending to the grid. According to Kempton, in a theoretical situation in which the vehicle is unplugged for six hours a day, a driver may earn up to $56 a month.

Dr. Kempton also detailed the aggregator system that is responsible for bidding on the amount of energy required by the grid each day and then documenting what energy is inputted by the EVs in order to recognize when the energy limit is reached.

This work has involved collaboration between Dr. Kempton’s team in Newark and international collaborators in Denmark.
