A description is given of work and results of an experimental and analytical study of the storage of hydrogen in motor vehicles using metal hydrides. The central purpose of the work was the identification, synthesis, and evaluation of hydrides having a potential for use in automobiles on a basis comparable to present gasoline fueled vehicles. Efforts of the studies included: (1) a review and rating of known and potential hydrides; (2) the preparation of a reference design; (3) an experimental search for new hydrides; and (4) the determination of engineering properties of candidate hydrides. The experimental search for hydrides was given priority over the reference design work. Several materials were identified by the initial review as having a potential worth investigating experimentally. These were magnesium and magnesium-aluminum alloys. A number of these materials did respond to relatively simple hydriding procedures. Hydrogen uptake was encouraging, but, in the time available for the effort, none of these alloys met the desired criteria. Vehicular use was considered feasible, however. The primary output of the reference design work was a mathematical model of the behavior of two hydride storage bed concepts. Overall consideration of the effect of using hydrides with various property differences provided a guide for the identification of candidate hydrides. The utility of known and available hydrides for automotive application is indicated. (auth)
