With growing population and the associated increase in the demand for transportation of people and goods, energy requirement is rapidly increasing. In developing countries like India, it is difficult to replace the existing automotive fleet with advanced technologies like electric and hybrid vehicles because of the energy density of internal combustion engines and poor infrastructure for sustainable operation of electric vehicles. To meet this gap of growing energy demand and to decrease the consumption of fossil fuels, it is necessary to find alternate fuels. Biofuels are one of the alternate fuels that can effectively replace fossil fuels. Among them alcohol fuels are gaining popularity as they can be synthesized from available biomass and other organic feedstock. By blending these alcohols with gasoline, sustainable drop-in-fuels can be formulated. But on the basis of production level, the price of ethanol/methanol may vary from place to place and as a result, the final price of blended fuel may become slightly expensive. Therefore, the concept of ternary blends is developed with the fuel properties same as that of any binary gasoline-alcohol blend. This paper is aimed at reviewing the literature available on multi-component gasoline-alcohol blends and discusses their merits compared to other blending options.Alcohol fuels, Biofuels ,Multi-component gasoline-alcohol blends, Ternary blends
