Energy is one of the most important commodities in modern life, but burning fossil fuels is our main source of energy, releases carbon dioxide, causing global warming. Due to rising cost of petroleum products and environmental concerns it has become imperative to make use of local resources as an alternate to petroleum fuels. Therefore, it is a world wide trend to explore and make use of biogas as an alternate fuel in vehicles generating from poultry litter. The present study reveals that enriched biogas potentials generating from poultry litter in Puduchatiram block for production of Bio-CNG to substitute compressed natural gas using in automobile and transport applications. Biogas can be used in automobiles after its purification. Removing CO2, H2S and water vapour and compressing it into cylinders makes it easily usable for transport applications such as three-wheelers, cars, pick up vans and etc. Taking these into account, the present status of the enriched biogas potential is assessed. The study shows that, the great enriched biogas potential (20,355 M³/day) and compressed biogas potential (14,533 Kg/day) available in Puduchatiram block. This technology ensures reducing GHG emissions, sustainable development, energy security and employment generation in the study area.
