RESUMO
In hydroelectric systems, during the rainiest periods of the year, there is surplus hydropower in the reservoir, some ofwhich is commercialized (secondary hydroelectric power) and the rest spills over producing no power. A manner of utilizing such lost power is converting it into an energy carrier, as, for example, electrolytical hydrogen. In this study such power utilization option is deeply analyzed, by the identification of potential secondary hydroelectric power in Brazil and the evaluation ofits utilization in hydrogen production. To achieve such aim, it was made a description of electrolitycal hydrogen production process, an estimation of the Brazilian potential for hydrogen production from secondary energy and the optimal capacity of producing hydrogen by association of secondary and firm power at a minimum cost; an evaluation of the Brazilian hydrogen market is also part of this work. Finally,one Brazilian hydroelectric power plant is taken as a study case, in which the yearly and monthly availabilities of secondary energy are evaluated, in order to evaluate the technical and economical feasibility of hydrogen production from this power and some economic uses of this hydrogen, as an energy carrier and as raw material for the chemical industry.
