Abstract: The present disclosure provides active venting control systems for use with liquid hydrogen tanks. The active venting control system allows a greater mass of hydrogen to be safely stored for a greater period of time. The systems is configured to actively monitor, control, and vent hydrogen based on a combination of pressure and fill level within the tank. When the tank reaches a predetermined fill level, the active venting control system is configured to vent the tank for a predetermined period of time. The active venting control system is configured to repeat the process during a transit and storage time, allowing the tank to be filled with a higher initial fill level and hold a greater mass of hydrogen compared to passive pressure relief systems.

Abstract: The present disclosure provides adaptive filling systems for use with liquid hydrogen-fuel tank modules. The adaptive filling systems determine, for each tank module, an optimal filling pressure based on passive pressurization due to parasitic heat transfer into the hydrogen-fuel tank during storage and transit. The adaptive filling systems identify a particular hydrogen-fuel tank module, the aircraft it will be loaded onto, the aircraft's estimated time of departure (ETD), the filling time, and the locations of the tank module and the aircraft. The systems fill different hydrogen-fuel tanks at different pressures in order to account for varying periods for storage and transit from the corresponding filling location to the corresponding aircraft or storage location.
