3.1.2.7 hydrogen powertrain systems

Hydrogen powertrain systems convert clean hydrogen into propulsive force using either direct combustion in gas turbines or fuel cells connected to electric motors. This technology offers a true zero-carbon flight potential, producing only water vapor during operation. Challenges in developing these systems lie in maintaining liquid cryogenic storage at -253 degrees celsius, managing inevitable fuel boil-off, and fitting bulky hydrogen tanks within aerodynamic fuselage constraints.
