ABSTRACT
The shipping industry has come a long way using combustion engines in transporting goods between continents, but in general the transportation sector accounts for a large fraction of air pollutant emissions. Health and environmental effects of air pollutants such as NOx, CO, VOCs, and particulates are leading to stricter tailpipe emissions regulations worldwide. [1, 2]. Virtually all transportation fuels today are derived from oil. Oil production is projected to peak worldwide within a decade and there no guarantee that oil will be enough for worldwide increase in consumption.
