Abstract
With the growing global energy need, the search for a viable, promising and sustainable energy matrix emerges as one of the main focuses of scientific research. In recent years, the role of renewable energies has gained increasing prominence, driving the discussion and approval of various public policies on a global scale. The United Nations (UN) launched the 2030 Agenda, an initiative that encompasses 17 Sustainable Development Goals (SDGs) to be achieved by the year 2030. In support of the 2030 Agenda, a large amount of research is being carried out around the world to develop fuels from clean and sustainable sources. However, developing a green energy matrix poses significant challenges for science and the political-economic sector. Fossil fuels are finite and are also relevant sources of environmental pollution, thus highlighting the preference for renewable sources. Hydrogen appears as a great potential, as it is a fuel with high calorific power and is the simplest and most abundant gaseous element in its chemical structure available in the universe. It can be obtained in several ways, including through processes with metals, such as oxidizing aluminum in an alkaline solution. The use of recyclable metals, such as aluminum, is a promising option for sustainable hydrogen generation processes. However, it is important to identify how the waste from sustainable hydrogen generation behaves, considering factors such as the origin of the reagent (aluminum) and the material of the reactor, so that the impact of the waste can be evaluated and, thus, provide an adequate destination for them. In this context, it is crucial to carry out an in-depth investigation of the industrial and technological applications of the products generated by the hydrogen generation reaction from aluminum, so that there is a guarantee of the proper disposal of waste, being an essential step to complete the energy supply chain in a sustainable way, successfully achieving a green circular economy.
