This paper compares four transportation energy conservation strategies using a comprehensive evaluation framework that takes into account how each strategy affects annual vehicle travel, and therefore mileage-related impacts such as traffic congestion, road and parking facility costs, and crashes. These mileage-related impacts tend to be large in magnitude compared with energy conservation bene...

A breakeven analysis of low carbon vehicle/fuel systems is conducted for the US for the year 2020, taking into consideration both private and external costs. All comparisons are made with respect to the conventional gasoline car as the baseline. Interestingly, the social cost of carbon prevailing in the literature is not high enough to justify the prioritization of low carbon vehicle/fuel techn...

Recently electric vehicles are becoming popular as an alternative of conventional fossil fuel vehicles. Conventional Internal Combustion Engine (ICE) vehicle uses fossil fuel which contributing a major part of overall carbon emission in the environment. Carbon and other green house gas emission are responsible for global warming and resulting climate change. It becomes vital to evaluate perform...

This paper investigates the importance of network effects in the demand for ethanol-compatible vehicles and the supply of ethanol fuel retailers. An indirect network effect, or positive feedback loop, arises in this context due to spatially-dependent complementarities in the availability of ethanol fuel and the installed base of ethanol-compatible vehicles. Marketers and social planners are int...

Based on an analysis of several case studies of alternative fuel introductions [ethanol, biodiesel, liquefied petroleum gas (LPG), compressed natural gas (CNG)], requirements for alternative fuels, vehicles, and the fueling infrastructure are postulated that are necessary for successful market implementation. Affordable vehicle technology and costcompetitive fuel were identified as the most cri...

This chapter focuses on some new definitions and methodologies of electric drives that are facing new challenges raised by alternative fuel vehicles. It starts with the objectives, fundamentals, and current research issues of alternative fuel vehicles based electric drives, before moving on to new definitions of unified modeling of the entire electric drive system and design of the proposed DC ...

the present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. various methods of hydrogen production for automotive applications have been discussed first. as the hydrogen production is one of the major challenges for application of proton exchange membrane (pem) fuel cells, especially in vehicular indus...

Alternative motor fuels have been advocated in the name of energy security, regional air quality, greenhouse gas emission reduction, and even economic savings. The Energy Policy Act of 1992 sets a goal of replacing 30 percent of conventional fuel use with alternative fuels by the year 2010. Earlier analysis using a single-period equilibrium model demonstrated the feasibility of EPACT’s replacem...

The transition to alternative fuels and vehicles presents many challenges that require long-range strategic thought and planning. Fuel producers must make expensive infrastructure decisions about which fuels to support years before they are sold. Vehicle producers must commit to new drivetrains on a similar long-range schedule. Whichever technologies prevail, hydrogen fuel cell, PHEV, BEV or bi...
