Hidrogênio verde, uma alternaƟva promissora em solos brasileiros:Uma revisão bibliográfica

Abstract

The mitigation of greenhouse gas (GGE) emissions has become a highlight since 2020 due to the meetings held by the UN and other organizations. Thus, data on global warming of the 1.5 °C increase /year that has been worrying scientists around the world came as a decisive factor for the energy migration of nations to renewable sources, thus reducing the emission of greenhouse gases, emitted mainly by large industries and energy sectors. Hence, this study carried out a literature review on green hydrogen's major energy source cited as promising in reducing greenhouse gas emissions. In addition, this study presents sources of this production, costs, and the place of Brazil in this production. The bibliographic review had the following descriptors chosen for the search: green hydrogen, hydrogen, fuel, energy, electrolysis, and Brazil. Applying the descriptors synchronously with the Boolean operators, we have the formations, green hydrogen AND fuel, green hydrogen AND Brazil, hydrogen AND fuel, hydrogen AND energy, hydrogen AND Brazil, and hydrogen AND electrolysis. The database chosen for the investigation was Periódicos Capes since the Federal University of Paraíba has an agreement for the availability of articles. As exclusion criteria adopted articles: before 2020 that did not contain renewable sources for energy production, hydrogen as an energy source or that was not a final product, that did not present hydrogen production processes, and research that did not use hydrogen as fuel. Also, the article titles were analyzed to verify the similarity or importance of the study. In total, 29 articles were found, and after applying the exclusion criteria, 18 were found. As a result, 10 authors of great relevance for this research were chosen.
