Hydrogen for transport and the B&E report. Oil provides most of the energy for transportation and oil will soon be in short supply. That is the reason why advocates of the hydrogen economy want to replace oil with hydrogen. Practical hydrogen powered trucks and automobiles must be the initial objective. Molecular hydrogen is currently receiving the most attention and financial support as the starting point for fuel cell energy supply. The literature and the many presentations that the committee heard indicate that the manufacture of molecular hydrogen is the consensus approach favored by the majority of leadership within the government, at universities, and in industry. stage "cascade filling" of the vehicles. A two stage cascade filling system combined with a booster compressor, or a multiple stage cascade filling system with more than three pressure banks are other options. This is to ensure that the on-board vehicle storage tank reaches the optimum fill pressure within the required Size: KB.

The space shuttle docks with the International Space Station in orbit. Credit: NASA For decades, NASA has relied upon hydrogen gas as rocket fuel to deliver crew and cargo to space. With the Centaur, Apollo and space shuttle vehicles, NASA has developed extensive experience in the safe and effective handling of hydrogen. For example, the rocket engines of each shuttle flight burn about , Safety issues surrounding conventional storage and transportation of hydrogen focus on the flammability and explosive qualities of gaseous hydrogen, as any accident involving the exposure of liquid hydrogen to the environment means evaporation into a gaseous state. The possibility also exists of a leak in piping or industrial equipment, presenting problems of detection and fire suppression. Once the vehicle reaches space, it must be protected from the radiant heat of the Sun. When liquid hydrogen absorbs heat, it expands rapidly; thus, venting is necessary to prevent the tank from exploding. Metals exposed to the extreme cold of liquid hydrogen become brittle. Moreover, liquid hydrogen can leak through minute pores in welded seams. Technological Air Transportation System Ground Requirements of Liquid-Hydrogen-Fueled Subsonic, Long-Haul Civil Air 6.

To get around this problem, turn the hydrogen gas into a liquid, which is denser than a gas. This means cooling the hydrogen to a temperature of ‑ degrees Fahrenheit (‑ degrees Celsius). Seriously cold. Although it’s denser than hydrogen, oxygen also needs to . strength requirements for a hydrogen fuel tank. This design served as a baseline for the development of a full-scale hydrogen conformable storage tank that would have a service pressure of 5, psig and a service life of 20 years. Conformable hydrogen storage tank design activities completed in . The results suggest that most MHDVs have sufficient space for hydrogen storage tanks under the side rails, behind the cab, and/or under the chassis to accommodate 90 percent of each vehicle.
