The potential of clathrate hydrates for hydrogen storage has already been demonstrated in various publications. Today, a major scientific and technological challenge would be the finding of a storage material that allows for storage of larger quantities of hydrogen, as required for new energy applications such as, for instance, in the transport sector and fulfilling the goals set by some energy agencies which require the achievement of storage capacities up to a mass fraction of 6% of hydrogen and with an environmentally clean and safe method by the end of 2010. If it would be possible to store hydrogen in structure sH clathrate hydrate (sH), this goal possibly could be achieved. Our previous work demonstrated for the first time the possibility to crystallize hydrogen clathrate hydrate in structure sH with 1, 1-dimethylcyclohexane, methyl tert-butyl ether (MTBE), and methylcyclohexane as promoters. In this work, phase equilibrium data (p, T data) are reported for hydrogen clathrate hydrate systems with liquid hydrocarbon promoters, all of them forming the structure sH. Experiments were carried out at pressures up to 100.0 MPa.
