Hydrogen is an ideal energy resource for vehicular applications because (i) it exhibits an inordinately high efficiency for energy conversion when employed in fuel cells, (ii) the end-product (water) in its utilization is not an environmental pollutant, (iii) it is remarkably light, and (iv) it is readily renewable. The storage of hydrogen, however,  remains a major obstacle to the universal acceptance of this gas as a technologically viable energy source. The primary  thrust in current research is not only towards the maximization  of the storage density but also on the optimization of the  storage (adsorption or hydriding) and delivery (desorption or dehydriding) processes. Recent developments in the search for  novel materials with enhanced hydrogen-storage capacities are described in this article.
