Abstract

The production of green hydrogen (bio-H2), biomethane (bio-CH4), and biogenic carbon dioxide (CO2) relies on an efficient process of biogas capture, purification, and storage, with the gas separation stage being a key factor in its viability. In this context, the development of advanced polymeric membranes emerges as a promising technological solution, capable of optimizing biogas purification in a selective and sustainable manner.The synthesis and characterization of these membranes are fundamental steps to ensure their performance in separating biogas components, enabling the efficient removal of impurities and enhancing the quality of the obtained products. Furthermore, optimizing the composition and structure of the membranes directly influences their durability, operational efficiency, and cost-effectiveness-essential factors for enabling large-scale application.Purified gases have high added value and various strategic applications. Biogenic CO2 can be used in industrial processes such as beverage carbonation and atmospheric control in food packaging. Biomethane stands out as a renewable alternative to natural gas, with potential applications in electricity and thermal energy generation or as a biofuel for transportation. Meanwhile, green hydrogen is emerging as a crucial energy vector for transitioning to a sustainable energy matrix.Thus, this study will focus on the production and characterization of polymeric membranes for biogas purification, evaluating their efficiency, stability, and optimal operating conditions. The application of this technology will significantly contribute to the valorization of biogas, promoting sustainability and strengthening the circular economy.
