FATORES DETERMINANTES PARA QUE A UTILIZAÇÃO DO HIDROGÊNIO VERDE NA GERAÇÃO DE ENERGIA ELÉTRICA SEJA ECONOMICAMENTE VIÁVEL

ABSTRACT Hydrogen is an ideal source of energy, because from its production to its final transformation, the environmental impact is low because it is a renewable and clean source. Because its transformation process is a closed chemical cycle that does not generate greenhouse gases. Therefore, this work has the following research question: What are the determining factors for the use of green hydrogen in the generation of electricity to be economically viable? This work will contribute to increasing the understanding of how to integrate green hydrogen into the energy mix in an economically sustainable way by analyzing the driving factors. As the object of the study is to identify in the current literature the factors that determine the economic feasibility of the use of hydrogen for the generation of electricity, this research is a bibliographic analysis of an exploratory character through articles published in scientific journals. To limit the number of publications to be searched and analyzed, search terms are limited to “Green hydrogen production,” “Green hydrogen plant,” “green hydrogen plant,” “cost of green hydrogen,” and “ammonia to transport hydrogen.” Through the study, six determining factors were identified for the use of green hydrogen in the generation of electricity to be economically viable. The factors are cost reduction, increased use of renewable sources, incentives for the adoption of green hydrogen, technological improvement, improvement in hydrogen transportation options, and improvement in hydrogen storage options. Key-words: Green hydrogen. Electrical energy. Environment.
