ABSTRACT
This chapter briefly describes the existing and promising alternative concepts of hydrogen storage, especially for automotive applications. While the dominating technology of hydrogen storage nowadays involves compressed and liquefied hydrogen gas, this chapter mainly deals with an H2 storage approach that particularly uses metal hydrides. The latter are potentially safer for the end users and can provide better volume efficiency. Various hydrides, which are currently under investigation for reversible hydrogen adsorption and desorption, are compared. A brief overview of these and some other nonhydride materials is given, and optimal empirical and theoretical criteria for their selection and further optimization are discussed.
