Hydrogen, a popular fuel with huge heat of combustion, shows an increasing concern due to its clean light-weighted and clean features, which may have the potential to ease the climate change caused by the greenhouse effect. Metal organic frameworks (MOFs) have been considered as a high-potential material in H2 storage due to their low cost and the ability to adsorb gases at high speed. In this article, different techniques of hydrogen storage will be discussed. It is founded that MOFs have a latent of H2 storage, which would replace the traditional methods. Several well-performed MOFs will also be examined: MOF-5 for its high deliverable hydrogen volumetric capacity and reasonable cost, NU-100/PCN-610 for its high excess gravimetric adsorption and the high-pressure swing at 77K, and MOF-210 and HKUST-1 for their high hydrogen capacities with high surface area. The possible factors influencing the performance are BET surface area, pore volume, temperature and pressure and metal-centres. Nevertheless, several limitations caused by the high-standard reaction environment, especially for pressure and temperature, may exist. This paper concludes the general situation of current MOF techniques used in H2 storage and provides reference significance for future research.
