Abstract
In the present invention methods for storing gaseous hydrogen employing an ionic liquid are disclosed. The ionic liquid is used to displace the volume in the storage tanks. By displacing the volume in the storage tanks with the ionic liquid, the storage pressure can remain constant and the 'stranded' gas can be eliminated. This constant pressure will also allow for a reduction in the number of storage tanks needed to provide the required inventory at hydrogen fueling stations. In addition, this constant pressure will provide a complete and fast fill to the vehicle.
