The social synergetic analysis of the biosphere and humanity shows that in near future two attractors (human paths) will really compete: the first is an irreversible biosphere catastrophe and the second is a motion along the vector 'Hydrogen energy -> Hydrogen economy -> Hydrogen civilization'. In accordance with the basic assumption of the social synergetics about a fundamental possibility of the mankind conscious choice of its own post-bifurcation path to the future, the analysis based on Kondratieffs study about large cycles of the economic development leads to the fundamental conclusion: two historical stages of Hydrogen Civilization will correspond to Kondratieffs sixth (similar to 2030-2090) and seventh (similar to 2090-2150) hydrogen energy technological cycles with a probability up to 100%.
