| Summary: |
The purpose of this paper is based on a review of technical literature on the topic of alternative fuel
for vehicles (AFVs) which describes the advantages and disadvantages compared to conventional
vehicles running on conventional fuels (diesel and gasoline).
In addition, the study included the emissions of a fuel cell vehicle (FCV) and internal combustion engine
vehicle (ICEV).Global warming; climate change, greenhouse gas (GHG) emissions, and the quality of
the air have all been a major concern in the next decades. It is important to identify the major
contributors to greenhouse gas emissions in order to develop effective methods and strategies for their
reduction. The transportation sector is responsible for a great percentage of the greenhouse gas emissions
as well as the energy consumption in the world [18].Ultimately; we will need to replace gasoline with a
zero – carbon fuel. All AFVs that have so far been promoted with limited success (electric vehicles,
natural gas vehicles, methanol vehicles, and ethanol vehicles) have been each suffered from several of
these barriers. Any one from these barriers can be a showstopper from an AFV, even where other clear
benefits are delivered.Increasingly alternative economies are being suggested, whereby the growing
energy demand of the future is met with greater efficiency and with more renewable energy sources such
as ethanol, methanol, biodiesel, hydrogen, wind, solar and biomass.
Hydrogen is being promoted as an alternative energy carrier for sustainable future. Many scientists argue
that its use as a transportation fuel offers a number of attractive advantages over existing energy sources.
It is a high quality carbon-free energy carrier, which can achieve improved efficiencies at the point of use
with reduced or zero GHG emissions over the entire “well-to-wheel” (WTW) life cycle. These benefits
are even future underpinned by the fact that hydrogen can be manufactured from primary energy sources,
such as natural gas, coal, biodiesel, ethanol, methanol, wind, solar and biomass, contributing towards
greater energy security and flexibility.
