Hidrogênio verde: revolucionando o future da energia limpa .

Abstract

Due to changes in international geopolitics, several countries have sought alter-natives for their energy matrices, often resorting to cleaner and renewable options. One promising alternative is the use of green hydrogen (H2V) to replace fossil fuels and petroleum derivatives, as it enables the reduction of greenhouse gas emissions. Furthermore, green hydrogen is highly versatile in its applications and can be used in several sectors, such as commerce, industry and mobility, and is called the “fuel of the future”. Hydrogen consumption has intensified in countries such as China and the United States, which are the two countries with the highest energy demand in the world. Countries with a wide range of natural resources and easy access to clean al-ternative energy sources have considered increasing their hydrogen production, such as Brazil, whose vast territorial extension and climatic conditions contribute to the country's consolidation as a major producer of H2V. Industrial, logistical, technical and management challenges are still the main problems to be overcome in order to con-solidate this resource as one of the main sources of energy in the world, since the energy transition to less polluting and renewable resources requires a high level of investment that can discourage potential interested parties. In this context, the study consisted of carrying out a bibliographic review on green hydrogen, considered a prom-ising alternative in the global energy transition, emphasizing the need for investments in technologies and infrastructure, as well as its importance in reducing climate change and strengthening relations in modern geopolitics.
