Abstract

The application of ionic liquids revealed a new dimension in many fields of chemistry. In the particular field of hydrogen storage system ionic liquids find application in several different ways. After a short introduction about the matter of hydrogen storage and its advantages and challenges, the different approaches of ionic liquid application in this field are presented. The different approaches can be classified into the application of ionic liquids as (i) solvent, as (ii) co-catalyst, as (iii) catalyst, as (iv) hydrogen storage material and as (v) stabilizing agent for nano particles. The benefit of ionic liquids for the system is discussed in this review.
