Hydrogen’s combustion properties made it as a capable fuel to combat the current situations of depletion of the fossil fuels and to safeguard the environmental pollution problems. Its energy content per unit mass and higher heating value is almost about three times that of current fossil fuels. Hydrogen ignites across a wide range of concentrations, from about 4 to 74 percent, and only requires a small amount of energy to initiate ignition. Moreover when hydrogen reacts with oxygen to generate energy, the resulting reaction product is water vapor. In view of the above hydrogen can be used as a fuel in internal combustion engines or in fuel cell vehicles. In this paper a thorough review was made to bring awareness among buddy researchers working on hydrogen about combustion fundamentals, its anomalies, fuel induction strategies, performance, emission and safety related aspects for utilizing it in IC Engines as an alternative fuel.
