Proposta de um sistema power-to-power como solução a intermitência das fontes solares de geração de energia

Abstract

The increasing dependence on energy, particularly electricity, has brought about the need for diversification of the energy matrix in order to enhance the security of the energy system. This diversification, coupled with a quest for sustainability, has led to an increased utilization of renewable energy sources such as solar and wind, which, however, face the challenge of intermittency. The objective of this study is to analyze the efficiency of a Power-to-Power system as a potential solution to address the intermittency issue in energy sources. Extensive literature references were examined, encompassing each component of the Power-to-Power system and presenting the key technical and functional concepts of the technologies involved in such a system. This work also provides a comprehensive overview of various technical aspects of current technologies for green hydrogen utilization, including types of electrolyzers, hydrogen storage technologies, and fuel cells. Based on the data obtained from the literature, the efficiency of a Power-to-Power system was calculated, and the obtained value was compared with established storage systems such as lead-acid batteries.
