Abstract
A hydrogen release material includes a complex metal hydride and an ionic liquid wherein the hydrogen release material has a lower hydrogen release temperature in comparison to the complex metal hydride alone. Also disclosed is a process of releasing hydrogen from a storage material including the steps of: providing a complex metal hydride; combining the metal hydride with an ionic liquid in a desired amount forming a mixture; and heating the mixture to a temperature releasing hydrogen wherein the temperature is lower in comparison to the complex metal hydride alone.
