A Life-Cycle Analysis of the Greenhouse Gas Emissions from Corn-Based Ethanol
9/5/2018
This analysis, conducted by ICF for the U.S. Department of Agriculture. This report has analyzed the current GHG profile of U.S. corn ethanol and two projected emissions profiles for 2022. The starting point is the GHG life-cycle analysis (LCA) done by the U.S. Environmental Protection Agency (EPA) in 2010 for U.S. corn ethanol as part of its Regulatory Impact Analysis (RIA) for the Revised Renewable Fuel Standard (RFS2). In the RIA, EPA projected that in 2022, the life cycle emissions associated with ethanol would be 21 percent lower than those of an energy equivalent quantity of gasoline.

The Role of Demand-Side Incentives and Charging Infrastructure on Plug-in Electric Vehicle Adoption: Analysis of US States. Paper No. 074032
7/13/2018
In the U.S., over 400 state and local incentives have been issued to increase the adoption of plug-in electric vehicles (PEVs) since 2008. This article quantifies the influence of key incentives and enabling factors like charging infrastructure and receptive demographics on PEV adoption. The study focuses on three central questions. First, do consumers respond to certain types of state level vehicle purchase incentives? Second, does the density of public charging infrastructure increase PEV purchases? Finally, does the impact of various factors differ for plug-in hybrid electric vehicles (PHEV), battery electric vehicles (BEV) and vehicle attributes within each category? Based on a regression of vehicle purchase data from 2008 to 2016, we found that tax incentives and charging infrastructure significantly influence per capita PEV purchases. Within tax incentives, rebates are generally more effective than tax credits. BEV purchases are more affected by tax incentives than PHEVs. The correlation of public charging and vehicle purchases increases with the battery-only driving range of a PHEV, while decreasing with increasing driving range of BEVs. Results indicate that early investments in charging infrastructure, particularly along highways; tax incentives targeting BEVs at the lower end of the price premium and PHEVs with higher battery only driving range, and better reflection of the environmental cost of owning gasoline vehicles are likely to increase PEV adoption in the U.S.

California Plug-In Electric Vehicle Infrastructure Projections: 2017-2025 - Future Infrastructure Needs for Reaching the State's Zero Emission-Vehicle Deployment Goals
3/27/2018
This report analyzes plug-in electric vehicle (PEV) infrastructure needs in California from 2017 to 2025 in a scenario where the State's zero-emission vehicle (ZEV) deployment goals are achieved by household vehicles. The statewide infrastructure needs are evaluated by using the Electric Vehicle Infrastructure Projection tool, which incorporates representative statewide travel data from the 2012 California Household Travel Survey. The infrastructure solution presented in this assessment addresses two primary objectives: (1) enabling travel for battery electric vehicles and (2) maximizing the electric vehicle-miles traveled for plug-in hybrid electric vehicles. The analysis is performed at the county-level for each year between 2017 and 2025 while considering potential technology improvements. The results from this study present an infrastructure solution that can facilitate market growth for PEVs to reach the State's ZEV goals by 2025. The overall results show a need for 99k-130k destination chargers, including workplaces and public locations, and 9k-25k fast chargers. The results also show a need for dedicated or shared residential charging solutions at multi-family dwellings, which are expected to host about 120k PEVs by 2025. An improvement to the scientific literature, this analysis presents the significance of infrastructure reliability and accessibility on the quantification of charger demand.

Charging Electric Vehicles in Smart Cities: An EVI-Pro Analysis of Columbus, Ohio
2/7/2018
With the support of the U.S. Department of Energy's Vehicle Technologies Office, the National Renewable Energy Laboratory (NREL) worked with the City of Columbus, Ohio, to develop a plan for the expansion of the region's network of charging stations to support increased adoption of plug-in electric vehicles (PEVs) in the local market. NREL's Electric Vehicle Infrastructure Projection (EVI-Pro) model was used to generate scenarios of regional charging infrastructure to support consumer PEV adoption. Results indicate that approximately 400 Level 2 plugs at multi-unit dwellings and 350 Level 2 plugs at non-residential locations are required to support Columbus' primary PEV goal of 5,300 PEVs on the road by the end of 2019. This analysis finds that while consumer demand for fast charging is expected to remain low (due to modest anticipated adoption of short-range battery electric vehicles), a minimum level of fast charging coverage across the city is required to ease consumer range anxiety concerns by providing a safety net for unexpected charging events. Sensitivity analyses around some key assumptions have also been performed; of these, consumer preference for PHEV versus BEV and for their electric driving range, ambient conditions, and availability of residential charging at multi-unit dwellings were identified as key determinants of the non-residential PEV charging infrastructure required to support PEV adoption. The results discussed in this report can be leveraged by similar U.S. cities as part of a strategy to accelerate PEV adoption in the light-duty vehicle market.

Compressed Natural Gas Vehicle Maintenance Facility Modification Handbook
9/28/2017
To ensure the safety of personnel and facilities, vehicle maintenance facilities are required by law and by guidelines of the National Fire Protection Association (NFPA) and the International Fire Code (IFC) to exhibit certain design features. They are also required to be fitted with certain fire protection equipment and devices because of the potential for fire or explosion in the event of fuel leakage or spills. All fuels have an explosion or fire potential if specific conditions are present.
This handbook covers the primary elements that must be considered when developing a CNG vehicle maintenance facility design that will protect against the ignition of natural gas releases. It also discusses specific protocols and training needed to ensure safety.

Designing a Successful Transportation Project: Lessons Learned from the Clean Cities American Recovery and Reinvestment Act Projects
9/27/2017
The largest source of funding for alternative fuel vehicle and infrastructure projects in the U.S. Department of Energy's Clean Cities program's history came from the American Recovery and Reinvestment Act (Recovery Act). In 2009, the 25 cost-share projects totaled nearly $300 million in federal government investment. This effort included the involvement of 50 Clean Cities coalitions and their nearly 700 stakeholder partners who provided an additional $500 million in matching funds to support projects in their local communities. In total, those 25 projects established 1,380 alternative fueling stations and put more than 9,000 alternative fuel and advanced technology vehicles on the road. Together, these projects displaced 154 million gasoline gallon equivalents (GGE) of petroleum and averted 254,000 tons of greenhouse gas (GHG) emissions, while supporting U.S. energy independence and contributing to regional economic development. During post-project interviews, project leaders consistently cited a number of key components - ranging from technical and logistical factors, to administrative capabilities - for accomplishing an effective and impactful project. This report summarizes the high-level project design and administrative considerations for conducting a successful transportation project.

Analysis of the Effect of ZEV Policies: State Level Incentives and the California Zero-Emission Vehicle Regulations
9/7/2017
This report assesses the effect of state-level policies on the sales of zero-emission vehicles (ZEVs) and plug-in hybrid electric vehicles (PHEVs). Two analysis approaches are applied. The first approach assesses the potential effect of state-level incentives through quantification of the monetary value of ZEV and PHEV incentives and comparison of these values to state-level sales of these vehicles. The second approach focuses on the effect of California ZEV regulations on sales in California and in the nine other states that have adopted these regulations. ZEV and PHEV sales in these ten states are projected through 2025 under a variety of scenarios based on the regulations and associated historic trends in sales and credit balances earned under these regulations.

Public Sector Fleet EV Procurement Examples: A Case Study of Three All-Electric Vehicle Procurements Conducted by the U.S. Navy, City of New Bedford, and City of Seattle
6/6/2017
The deployment of EVs helps fleets to reduce air pollution from vehicle emissions and lower operating costs associated with maintenance and fueling. However, EV procurement by fleets has been limited by the higher up-front purchase costs and lack of availability of EVs compared to their gasoline counterparts, as well as the availability of charging infrastructure. Despite the existing barriers, many state and local public fleets have successfully integrated EVs to their fleets, and have used innovative procurement strategies to reduce the acquisition costs of EVs. This case study explores EV procurements conducted by the U.S. Navy, the City of New Bedford in Massachusetts, and the City of Seattle in Washington State—examples of public fleet procurements that captured financial incentives to reduce the vehicles’ upfront cost.
