\n\nIn our series on the state of alternative propulsion projects, we are looking at different hydrogen-fueled propulsion systems.\n\nHydrogen can either be processed chemically in a fuel cell to produce electrical power, which is then coupled to an electrical motor system, like for hybrids or battery electric aircraft. The advantage is that the system gets rid of the inefficient batteries that kill these systems.\n\nThe other alternative is to burn the hydrogen in the combustor of a gas turbine. The advantage is we keep the high power to mass ratio of a gas turbine with a heavier and more complicated fuel system, but a lighter fuel than Jet Fuel\/SAF.\n\n<\/div>\n<\/div><\/blockquote>\nPour en savoir plus :\u00a0The state of alternative propulsion aircraft?
