Cryogenic, compressed, and liquid hydrogen fuel storage in vehicles
Hydrogen is the viable energy carrier of future energy and transportation systems due to its clean emissions, light weight, and abundance. Its extremely low volumetric density, however, presents significant challenges to storage onboard vehicles. The study involves a survey of the current state of …

Trade-Space Analysis of Liquid Hydrogen Propulsion Systems for Electrified Aircraft
… ingestion, high-temperature PEM fuel cells, and liquid hydrogen fuel were examined. Aviation turbine fuel (ATF) and liquid hydrogen were compared using the payload-fuel energy intensity (PFEI), defined as the fuel energy required per product of range and payload. For a given mission, it was found …

The Safe Removal of Frozen Air from the Annulus of a Liquid Hydrogen Storage Tank
Large Liquid Hydrogen (LH2) storage tanks are vital infrastructure for NASA. Eventually, air may leak into the evacuated and perlite filled annular region of these tanks. Although the vacuum level is monitored in this region, the extremely cold temperature causes all but the helium and neon …

Permeability and Flammability Study of Composite Sandwich Structures for Cryogenic Applications
… reinforced plastics have been considered for the liquid hydrogen tanks. Materials selection is based upon mechanical properties and containment performance (long and short term) and upon manufacturing considerations. The liquid hydrogen tank carries shear, torque, end load, and bending moment due …
