Modelagem matemática e otimização de vaso de pressão para armazenamento de hidrogênio verde

Abstract

In recent decades, several lines of research have emerged to enable studies focused on minimizing the environmental impact generated by the use of fossil fuels. Renewable energy sources, mainly solar and wind energy, have gained even more strength and have high growth potential in the next 30 years. Despite all the benefits, there are several questions about how to cheapen the storage of energy generated by these clean sources without relying on more expensive components, such as batteries. With this focus, alternatives arise such as the production of hydrogen, which in recent years has gained great notoriety worldwide, nationally and regionally. In order to use increasingly cleaner sources, it is needed to know about the production, storage and use of the products generated. One of the challenges of hydrogen production is its subsequent storage for use in other lines and this topic has been the object of interest for many studies. Therefore, this essay proposes different possibilities for storing hydrogen gas, taking into account economic and safety aspects through mathematical modeling, objective function definition and restrictions. The optimal results obtained with the model solution show limits for the choice of vessel based on scenarios and aspects related to the project, such as operating pressure and electrolysis capacity of the green generation plant.
