RESUMO

In the last decades technological development of energy sector has evolved in connection with environmental worries, in as much as these ones have also influenced options for some specific energetic technologies. Current context is characterized by fossil fuel and intemal-combustion engine, such reality presents steady increase of energy consume and brings debates related to energy security, fossil sources breakdown and necessity of decarbonization. Accordingly, necessary decrease of CO2 emissions justify a switch to environmentalIy less aggressive energetic options that can also supply energy to stationary and vehicular applications. The option analyzed in this thesis is hydrogen as energetic vector and fuel celI as conversion system; supposing effective insertion of such technologies, it would influence alI over society structure as welI as result on Hydrogen Economy establishment. ln this way, intemational actions reveal initiatives originalIy from IPHE (International Partnership for the Hydrogen Economy) and IEA (International Energy Agency). Both them influence Brazilian guidelines produced by research institutions and public policy development. ln Brazil there are two official documents about Hydrogen Economy: PROH2 (Programa de Ciência, Tecnologia e Inovação para a Economia do Hidrogênio) and Roteiro para a Estruturação da Economia do Hidrogênio no Brasil. This thesis intends to analyze terms for incorporate of current Brazilian energetic regime, which supplies stationary and vehicular energy, by Hydrogen, produced from renewable sources, and by fuel celIs. As subsidy to this analysis, we borrowed concepts of technological paradigm and trajectories from evolutionist theory. In order to analyze intemational actions and proposals for Hydrogen Economy we described prospective researches on such possibility of technological rupture, i. e., a current regime breaking. In order to understand the national context we employed under-structured interviews with area coordinators of Guideline for Organization of Hydrogen Economy in Brazil, document that have been considered a major Brazilian advance for a National Policy to Hydrogen Economy and a National Program for Hydrogen Production and Use. These interviews were useful to Brazil perspectives surveying, detailed here as obstacles and opportunities, which had largely correspondence with our bibliographic review. Among the national obstacles, besides the necessity of public policies, it shows up difficult transference of scientific projects to a pre-commercial leveI, as welI as necessity of an infrastructure for production, storage and distribution of Hydrogen, problems widely debated around the world. Among the opportunities to the country it shows up the already developed knowledge in production and use of renewable sources, mainly hydric and biomass. About the conditions for changes in the Brazilian energetic regime, has been the fact that Brazil is a country peripheral that tends to folIow the technological development observed in the intemational environment, and the predominance of distributed generation, of hydrogen derived from renewable sources, and of the fuel celI stationary
