Abstract :Air transportation phenomenon is placed with sharing of world energy consumption between 2.5% and 5% totally and showing an increasing perspective approximately 4.8% per year .   With the increasing world population and the energy consumption, the aviation industry has led the technology and researches to alternative and/or renewable energy sources depending on the risk of depletion on kerosene fuels and its effects on the price increasement and environmental negativeness. Hydrogen energy, which H 2 is the most abundant element in the universe and most of it exists in the form of water and organic compounds, is considered the most promising fuel for all vehicles which need to effective energy. The diversity of availability and the renewability of hydrogen fuel have opened the way for use in different engineering applications with the creation of an environmentally friendly. The aerospace and aviation sectors have been the earlier to recognize the importance of using this fuel. The union of aviation industry and hydrogen energy has been met with NASA’s works and has become remarkable position with the developing technology. This paper aim is touched upon the system of hydrogen usage strategies in aviation as a fuel. For this purpose, the brief history of using H 2 in aviation were presented, then benefits and challenges were given with explanatory, engineering technology of usage H 2 were analyzed, fuel cell applications and liquid forms of H 2 is explained as a focus of fuel and storage necessity were discussed, new technologies approachment were analyzed and given with comparisons. As a result, a mini but detailed review perspective on state of art on usage hydrogen energy in aviation would be emphasized.
