Nesta dissertação é apresentada uma revisão bibliográfica sobre o hidrogênio renovável, investigando o atual cenário das pesquisas pertinentes à produção, transporte, armazenamento, distribuição, logística e infraestrutura, necessárias à manutenção da sua cadeia de valor. Este estudo foi conduzido através de uma revisão de artigos nas bases de dados Scopus e Web of Science, buscando extrair as informações mais relevantes sobre o tema. Desde a década de 90, o número de publicações sobre hidrogênio renovável aumentou 310600%. Encontrou-se 12467 artigos sobre o tema, sendo apenas 284 relacionados à sua
cadeia de valor. Desse total, apenas 52 publicações contribuem com o avanço de algum dos pilares da cadeia. Submeteu-se essas publicações à análises quantitativas e quali- tativas. Apenas 30,77% delas trabalham mais de um dos elementos da cadeia e apenas 5,76% relacionam três ou mais elementos da cadeia de hidrogênio renovável. Os resultados indicam a inexistência de estudos de impacto sobre o tema, que considerem os diversos aspectos da cadeia de valor do hidrogênio renovável. Destaca-se a disparidade entre as aspirações políticas e o cenário atual do hidrogênio renovável. Essa inconsistência reforça a necessidade de investimentos em infraestrutura, além de metas e prazos mais exequíveis para a transição energética. É necessário aceitar que este é um processo lento e que os prazos anunciados nos acordos para descarbonização até 2050 são irrealistas.
In this dissertation, a literature review on renewable hydrogen is presented, investigating the current landscape of research relevant to its production, transportation, storage, distribution, logistics, and infrastructure necessary for maintaining its value chain. This study was conducted through a review of articles in the Scopus and Web of Science databases, aiming to extract the most pertinent information on the topic. Since the 1990s, the number of publications on renewable hydrogen has increased by 310600%. A total of 12467 articles were found on the subject, with only 284 related to its value chain. Among these, only 52 publications contribute to advancing any of the pillars of the chain. These publications were subjected to quantitative and qualitative analyses. Only 30.77% of them address more than one element of the chain, and only 5.76% relate to three or more elements of the renewable hydrogen chain. The results indicate the absence of impact studies on the subject that consider the various aspects of the renewable hydrogen value chain. There is a notable disparity between political aspirations and the current lands- cape of renewable hydrogen. This inconsistency underscores the need for investments in infrastructure, as well as more achievable goals and timelines for energy transition. It is necessary to acknowledge that this is a slow process and that the deadlines announced in decarbonization agreements until 2050 are unrealistic.
