A method of storing a gas comprises absorbing a gas into or onto an absorbent medium, in one example by cryosorbing the gas. The cryosorbed gas is then encapsulated. Encapsulating the cryosorbed gas increases the temperature at which the absorbent medium can be kept before the cryosorbed gas is released, The encapsulation layer can be provided by freezing a material that has a lower vapour pressure than the gas. One suitable material for forming the encapsulation layer in this way is water. This method can be used to store gases having a very low boiling point, such as hydrogen or oxygen.
