Abstract

The use of hydrogen, the most abundant element in nature, is being actively pursued as a potential energy vector that could replace fossil fuels. Its combustion produces only heat and water, and it can be efficiently combined with oxygen in a fuel cell to produce electricity, a clean and convenient carrier of energy that has many possible applications including consumer devices, lighting, refrigeration and transportation. Its use as a power source for commercial transport vehicles has been considered for many decades [1], and prototype vehicles with satisfactory performance have already been built. However, realizing the promise of hydrogen as a widely used fuel requires substantial development of the means for its production, storage, and subsequent use. This chapter addresses the problem of hydrogen storage with particular application to transportation and portable power applications, which require a medium combining high hydrogen density with fast kinetics for charging and discharging at moderate temperatures and pressures, i.e., close to ambient.
