If you can organize graphene in three dimensions, you can greatly expand the amount of hydrogen you can store in graphene. This could greatly reduce the cost of hydrogen storage, and even allow for bulk room-temperature storage. Researchers out of the Istituto Nanoscienze, a research consortium, published results from an experiment that demonstrates organizing graphene in three dimensions is possible.

A research consortium has discovered how to organize graphene in three dimensions. This novel process could be used to store larger quantities of hydrogen and develop more sensitive gas sensors….
He found the relevant expertise at the Institute for Sensor and Actuator Systems at the Technical University of Vienna, Austria. Here, Professor Ulrich Schmid‘s group has been researching processes for years that make it possible to integrate extremely fine, porous structures into dense materials in a controlled manner….
Dr. Stefano Veronesi, a member of Dr. Heun’s research group at the Istituto Nanoscienze, explains what the application of this process means in terms of hydrogen storage: “Graphene can bind (store) molecular as well as elemental hydrogen on the surface. At room temperature, however, only elemental hydrogen binds well to graphene. Molecular hydrogen, on the other hand, forms only a very weak bond with the graphene surface. By selective functionalization (“grafting”) of the graphene surface, the ‘storage’ capability of the graphene surface can be significantly increased even at room temperature. How much hydrogen can be stored is determined by the graphene surface area present – the more graphene, the more hydrogen can be stored.”
