Utility emissions associated with electric and hybrid vehicle (EHV) charging
Abstract
This project is a joint effort between the U.S. Department of Energy (DOE) and the Electric Power Research Institute (EPRI) to conduct a comprehensive, in-depth assessment of the emission impacts of electric and hybrid vehicles (EHV's). The study determines local and regional emission impacts under a variety of scenarios, covering both conservative and optimistic assumptions about vehicle efficiency, power plant efficiency, and other factors. In all scenarios, EHV use significantly reduces urban emissions of CO, VOC, and TSP. Changes in NO(x) and CO2 emissions are very sensitive to average or marginal power plant emissions and vehicle efficiency assumptions. NOx and CO2 emissions changes vary dramatically by region. Certain combinations of EHV and CV scenarios and regions result in significant reductions, while other combinations result in significant increases. Careful use of these results is advised. In all scenarios, SO2 increases with EHV use although the amount is small--less than 1% of total utility emissions even with the deployment of 12 million EHVS. But because of emission cap provisions of the Clean Air Act Amendments of 1990, national SO2 totals will not be allowed to increase. Thus, utilities will have to apply more stringent measures to combat increased SO2 emissions due to the increased use of electric vehicles.
