Partnership request description:  It is well known that, fossil fuels resources – headed by petroleum and natural gas – are being depleted rapidly and the environmental problems (climate change, acid rains, ozone layer depletion, pollution, oil spills, etc.) caused by their utilization are increasing. Rising energy prices and the growing environmental damage are hurting the economies of the developing countries mainly, and the income per capital gap between industrial countries and developing countries is widening. This is causing many problems between the developing countries and the industrial countries, including ever-growing illegal immigration to industrial countries such as E.U. and U.S.A. The Hydrogen Energy System is the permanent answer to these interrelated global problems. Under this system, each country will be able to produce the fuel it needs, i.e., hydrogen, to power its economy, using the primary energy sources available. Therefore, they will not be affected by the rising energy prices and will not spend foreign exchange to import petroleum and/or natural gas. This will speed up their economic growth and at the same time eliminate the environmental damage. Consequently, the Hydrogen Economy will help developing countries develop faster, protect the environment, and eliminate the tension between the developing countries and the industrially developed countries. The hydrogen safe storage and transportation are the problems restrained the introduction of hydrogen energetics. Solving this problem can contribute considerably to the fast progress of hydrogen at the power market. The hydrogen storage in solids meets the requirements and supply most of the needs of life. The hydrogen density in the volume unit for the majority of hydrides exceeds the density of liquid hydrogen. The bulk of such materials are not explosive, containers for their storage are compact and cheap and it is less of a problem for these containers transit than that during liquid and gaseous hydrogen transportation. The recently found fourth allotropic modification of carbon, as fullerene, can be one of such materials. As pointed out in [1], the fullerite properties, as volume (8,25?1022 H atoms/cm3), gravimetric (7,7 wt.% H) and electrochemical (2000 mA/h?g) capacities, exceed many similar properties of metal hydrides and hydrocarbons. A series of preliminary experiments have been conducted to evaluate the full hydrogenation of fullerite C60; hydrofullerenes have been produced experimentally with the variable content of hydrogen. The optimum regime of C60 hydrogenation has been determined resulting in the full hydrogenation of fullerene molecule C60. As was apparent after the tests, the sequence of formation of hydrogenated fullerene molecule C60H60 in fullerite has been going in the following order: the molecular hydrogen dissolution in octahedral interstices of fcc lattice of fullerite, the dissociation of hydrogen molecules in going from octa- to tetrahedral interstices, the interaction of hydrogen atoms with fullerene molecule. It has been demonstrated that chemisorption process of hydrogen by molecule C60 is limited by diffusive processes in fullerite after hydrogen concentration conformed to C60H36. The spectral analysis have shown that the second stage process of chemisorption follows the compressive shell model. The suggestion of the model of processes going on at the interaction between H2 and fullerite C60 has been made. The mechanism for the definition of hydrogenation degree of molecule C60 has been proposed in the present paper. The task facing the project researchers is to solve a problem of determination of technological process and catalyst for the performance of hydrogen desorption process from fullerite in the more soft conditions. The solution of the problem of the reversible hydrogenation of each carbon atom in the frame of fullerene molecule will allow to create the hydrogen storage with the capacity up to 7,7 wt.% H.
