Estimation of Liquid Hydrogen Fuels in Aviation

As the demand for alternative fuels to solve environmental problems increases worldwide due greenhouse gas problem, this study predicted liquid hydrogen fuel in aviation achieve ‘zero-emission flight’. The models of an aircraft and all sectors were produced based on prediction fleet growth through classification currently operated aircraft. Using these models, required amount total cost also calculated when various regulations satisfied. a result, it was found be necessary convert approximately 66% 100% from existing 2050, according regulations. annual 4.7–5.2 times higher beginning high production cost, but after 2030, will maintained at almost same price, that rather low compared jet fuel.
