Hydrogen as the possible future generation fuel has been realized for some time now for various reasons including its considerably high heat of combustion and also the feasibility of generating the fuel from renewable sources, water in a variety of ways including the attractive propositions like photo-electrochemical or photo-catalytic pathways. However, various issues with respect to hydrogen economy have to be considered in all the sectors of energy conversion processes namely generation, storage and distribution [1, 2]. The science and technology of both generation and storage of hydrogen have been receiving considerable attention for the past over 4 decades. In spite of concerted attempts [3-5] for achieving the DOE stipulated standard of 6.5 weight percent storage of hydrogen in solid state, the reported values different considerably due to various reasons including possibly some oversights in careful experimentation and measurement. However, among the possible solid state storage media for hydrogen, storage, carbon materials provide innumerable opportunities in terms of type of solid state matrices that can be exploited and also examine various experimental variables in terms of pressure and temperature, which are the parametric demands on the storage capacity for potential applications including transport. The main focus of this presentation is to examine why the necessary and sufficient storage of hydrogen in carbon materials has not yet been achieved.
