A process of hydrogen storage in the form of hydrate by utilization of liquefied natural gas(LNG) cold energy was proposed. Hydrogen was recovered from exhaust gas by pressure swing adsorption method, and formed gas hydrate with ice powder under a pressure of 35 MPa and a temperature of 140 K. The process analysis was carried out with partially numerical simulation by Aspen Plus and theoretical calculation. The results show that the energy consumption of hydrogen stored in the hydrate form is 12058 kJ/(kg.H2) and of this hydrogen storage process, the ratio of spent energy to stored energy is 0.10 , which is superior to the most of the other method. The research indicated that if there is cold energy with low temperature available, hydrogen stored in the hydrate form is a method of feasible and energy-efficient.

The performance of an adsorbed natural gas (ANG) storage system with natural convection heat transfer between the ANG bed and the ambient air is studied. Results are obtained for the bed without and with external fins on ambient air side. A one dimensional transient conduction model with suitable kinetic equation is formulated to simulate the performance of the bed filled with a homogeneous mixture of activated carbon and graphite. The model duly considers non-ideal behaviour of natural gas, variable specific heat of the adsorbed phase and heat of adsorption. Results are obtained for the case of constant pressure charging and constant flow discharging. The performance of the ANG bed is evaluated in terms of delivery capacity and discharge time. Results are obtained at an ambient temperature of 308 K and 35 bar for a charging time of 3.34 min. It is found that under this condition, the bed temperature increases by 70 and 45K and the storage capacity reduces by 75 and 60% without and with external fins, respectively. During discharge also, due to insufficient heat supply the bed temperature drops to very a low value thereby increasing the amount of adsorbate retained at the end of discharge process. This study clearly shows the need for improving the heat transfer rate from or to the ANG bed for higher delivery capacity.
