Study on sustainable transportation fuels based on green house gas emission potential

© 2018 IEEE. Presently transportation sector heavily depends on fossil fuel sources for meeting energy needs. The major issues with fossil sources at present include their limited reserves, highly polluting nature and geographically concentrated in few regions. This paper compares the GHG emission potential of bio-CNG, bio-diesel and hydrogen with fossil diesel and CNG when used with buses. Bio-CNG, bio-diesel and hydrogen have potential to be produced in decentralized as well as centralized stations with relatively lower emissions as compare to fossil sources. GREET (Green House Gases, Regulated Emissions, and Energy use in Transportation) model is used for GHG emission analysis. Results shows that hydrogen produced from renewable sources emits least GHG emissions and have potential to become future fuel.
