PRESSURE-HYDRIDE HYBRID TANK

Manufacturing and storing hydrogen gas

Metal hydride with a wt. ratio of hydrogen to hydride of at least approx. 1:15 is collected in a tank, the hydride heated to decomposition point in order to produce hydrogen gas, the latter is fed to an energy source using hydrogen during the production of energy, and the decomposition products of the hydride left in the tank are subjected at a temp. of approx. 140- approx. 250 degrees C and at a pressure of approx. 5.25- approx. 141 kg/cm2 (75-2000 psi) to the effects of elementary hydrogen for a period of time sufficient to convert the decomposition products back into metal hydride. Storage container can possess any form, cylindrical, spherical or box-shaped for example. It can be manufactured sufficiently small to be transported by one person, or be large enough to supply a vehicle using hydrogen, and even larger in the case of supplying a building. Since these containers do not have to withstand extremely high pressures they can be made of aluminium, magnesium, beryllium and their alloys, the wt. forming part of the total wt. of the hydrogen generator.
