Abstract:

As manufacturing processes using helium have increased worldwide, so has the demand for helium. Since helium is a non-renewable resource, this increased use in manufacturing has led to dwindling supplies of helium worldwide and a corresponding increase in cost. At the same time the use of lighter than air LTA vehicles, such as aerostats for military and commercial applications, has increased. Traditionally these vehicles have been inflated using helium. However, with the rising cost and scarcity of helium, the use of hydrogen gas to inflate LTA vehicles has been gaining greater acceptance. This report focuses on the generation of hydrogen gas as an alternative to helium as a lighter than air gas source.
