In this paper, a program of electrolytic hydrogen energy for the Ceara state in Brazil is proposed. Hydrogen will be produced through the assistance of photovoltaic cell panels and wind turbines. The generated hydrogen will serve as an energy carrier and will be used in every application where fossil fuels are being used today. The scenarios of fast and slow introduction of hydrogen and of no introduction of hydrogen were envisaged. Results indicate that the introduction of renewable energy hydrogen will increase the energy consumption and the gross internal product per capita of the Ceara state. In the same time it will reduce pollution originated from fossil fuels combustion and consequently will increase the quality of life of the population of such federal state of Brazil.
