Williams Department of Chemical Engineering, University of Arizona, Tucson, Arizona Because of diminishing reserves of convenient to use fossil energy sources, as well as environmental considerations, a serious research effort is underway worldwide to develop alternative long-term primary energy sources. Most of these alternative sources have the disadvantages of providing energy in forms which are difficult to store and transport. One possible solution to this problem is to convert the primary energy into chemical potential energy by decomposing water to form hydrogen which can be stored and transported with relative ease. The hydrogen energy system offers many attractive features including minimal environmental impact as well as a steady-state cycle. G. De Beni and C.
