Why is hydrogen used as fuel in a scramjet engine? - question from name withheld ... The LHV for hydrogen is 119,600 kJ/kg. JP-8, another fuel commonly used in military aircraft, has a LHV of only 43,190 kJ/kg, less than half that of hydrogen. Simply put, hydrogen provides more "bang" per kilogram than JP-8,
