Abstract(s)
O abastecimento energético mundial baseia-se em combustíveis fósseis. Contudo, dadas as suas desvantagens, há um esforço global de transição energética para limitar o aumento da temperatura global a 2ºC. O setor dos transportes é dos mais poluentes, emitindo cerca de 20% das emissões de dióxido de carbono. O hidrogénio é uma alternativa atrativa aos combustíveis fósseis que pode ser usado tanto para a mobilidade, produção de eletricidade, entre outras. A tecnologia de célula de combustível surge como alternativa líder face aos motores de combustão interna. No entanto, e apesar do grande potencial de utilização do hidrogénio na mobilidade em Portugal, é possível verificar uma quase inexistência desse mercado que coloca Portugal numa posição de atraso comparativamente com outros países. Tendo em conta os seus benefícios e potencial, quais são os fatores que explicam a baixa presença dos veículos a célula de combustível no mercado português? Qual é a forma mais adequada de potenciar este mercado e assim retirar os benefícios que daí poderão advir? O objetivo desta investigação é estudar quais são os fatores explicativos da baixa adesão ao hidrogénio na mobilidade, em Portugal. A análise do problema foi desenvolvida através da realização de entrevistas a profissionais da área do hidrogénio e, posteriormente, analisando o seu conteúdo à luz de uma metodologia qualitativa. Foram obtidos, assim, uma série de fatores explicativos para a baixa adesão ao hidrogénio na mobilidade, em Portugal e, ainda, um conjunto de medidas propostas para a sua potenciação.
The world's energy supply is based on fossil fuels. However, given its drawbacks, there is a global energy transition effort to limit global temperature rise to 2°C. The transport sector is among the most polluting, emitting about 20% of carbon dioxide emissions. Hydrogen is an attractive alternative to fossil fuels that can be used for both mobility, electricity production, among others. Fuel cell technology emerges as a leading alternative to internal combustion engines. However, and despite the great potential for the use of hydrogen in mobility in Portugal, it is possible to verify a near absence of this market that puts Portugal in a position of backwardness compared to other countries. Given their benefits and potential, what are the factors that explain the low presence of fuel cell vehicles in the Portuguese market? What is the most appropriate way to boost this market and thus derive the benefits that can come from it? Therefore, the objective of this research is to study what are the explanatory factors of low hydrogen adherence in mobility in Portugal. The analysis of the problem was developed by conducting interviews with professionals in the field of hydrogen and, subsequently, analyzing the content of the interviews in the light of a qualitative methodology. Thus, a series of explanatory factors were obtained for the low adherence to hydrogen in mobility in Portugal and also a set of measures proposed for its potentiation.
