Análise comparativa de tecnologias de extração de hidrogênio para aplicação em sistemas de geração elétrica renovável

Abstract

The growing global demand for sustainable energy sources and the need to reduce greenhouse gas emissions are encouraging the search for clean and efficient energy alternatives. In the current context, hydrogen presents itself as a promising energy potential, capable of complementing renewable electricity generation systems. The objective of this work is to comparatively analyze two hydrogen extraction technologies, focusing on their application in the generation of electricity from renewable sources. The techniques of water electrolysis, with energy from sources such as solar and wind, and water photolysis through photocatalytic systems will be investigated. The methodology used aims to research content that includes technical, economic and environmental aspects of each technology, challenges related to energy efficiency, technological limitations, and efficiencies of the materials used in the extraction, aiming to identify advances in research and development and the most economically viable alternative for hydrogen extraction on a commercial scale for electricity generation.
