The Responsible Battery Coalition, in partnership with the University of Michigan Center for Sustainable Systems, launched a comprehensive research project to compare the total cost of ownership of gas and electric vehicles (EVs). Where, when and for whom are EVs most cost-effective? Anticipated driving patterns.
A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). The Postal Service said in February that at least 10% of the new mail trucks would be electric.
The US DRIVE Cradle-to-Grave Working Group has published the “Cradle-to-Grave Lifecycle Analysis of US Light-Duty Vehicle-Fuel Pathways: A Greenhouse Gas Emissions and Economic Assessment of Current (2015) and Future (2025–2030) Technologies” Argonne National Lab Report. C2G GHG emissions of various vehicle-fuel pathways.
The study provides a comprehensive analysis of the cost and greenhouse gas (GHG) emissions of a variety of vehicle-fuel pathways; the levelized cost of driving (LCD); and the cost of avoided GHG emissions. Selected fuel pathways were constrained to those deemed to be nationally scalable in the future.
They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Over an array of possible conditions, the median TCO of electric trucks is 22% less than that of diesel trucks on the NYCC. Battery replacement along with EVSE will also greatly affect the relative TCO of the electric truck.
For the study, they define EVs as including both battery-electric (BEV) and plug-in hybrid electric (PHEV) vehicles. Only in the case of high EV market share and a high renewable electricity standard (RES) do EVs make a material contribution to greenhouse gas (GHG) reductions, they found. —Choi et al.
Do they receive HOV access for their improved fueleconomy and ultra low emissions? In fact in 6 of the states, diesel fuel is penalized with additional state taxes. So diesel fuel gets taxed twice or penalized twice at the federal and state level. This helps us to make better fueleconomy and good emissions.
Though there are some exceptions to these positive results for some of the diesel versions of vehicles from a total-cost-of-ownership perspective, the overall direction of the results supports the idea that diesel vehicles are competitive within the U.S. —Bruce Belzowski.
The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. The electric truck is relatively more cost-effective on the NYCC and when VKT demand is higher. Cost-competitiveness of the electric truck diminishes in drive cycles with higher average speeds. Credit: ACS, Lee et al.
