Gas hydrates have been viewed as a potential energy source and a possible energy carrier. They are essentially crystalline between water molecules and certain gas molecules under suitable pressure and temperature. Theoretically, they can store a number of gases like carbon dioxide, hydrogen, and methane. Methane storage in the hydrate form has been investigated due to its large storage quantity. However, storing methane in the hydrate form has been challenging due to its slow formation between water and methane. That is, partly, because of low diffusion rate of gas in water, long hydrate formation time, and stability of the hydrates. To decrease the methane hydrate formation time and increase the storage capacity, porous media particularly activated carbon was chosen to increase the interface area between gas and water. Therefore, the induction time or the first methane hydrate formation, the storage capacity, and the effect of activated carbon size in the system will be discussed. Moreover, the hydrate promoters such as tetrahydrofuran (THF) and sodium dodecyl sulfate (SDS) are also included in this work.
