This panel discussion, part of the Brazil Energy Conference, focuses on the technological challenges and opportunities for green hydrogen production in Brazil. The moderator, Eric Fernando Boec, introduces two experts: Magno Fonseca Santos, a researcher at SENAI Cimatec, and Professor Enio Pontes, who coordinates the LAMEF laboratory at the Federal University of Ceará. The discussion begins with an overview of Brazil’s potential as a global player in green hydrogen due to its abundant renewable energy resources and existing industrial base. However, the panelists highlight significant challenges, including the importation of over 90% of the supply chain inputs, lack of local electrolyzer manufacturing, and the need for integration between research institutions, government, and industry. They emphasize the importance of moving beyond exporting raw hydrogen to developing local value-added industries. The conversation then shifts to specific technological bottlenecks, such as the reliance on Nafion membranes in PEM electrolyzers, which are synthetic and polluting. Professor Pontes presents an innovative project at LAMEF developing a membrane from chitosan, derived from shrimp and crab shells, combined with graphene oxide and nanocellulose, aiming to create a sustainable and locally produced alternative. This project, funded by FINEP, seeks to scale up production and compete with global membrane suppliers. Magno Fonseca Santos discusses the economic viability of new materials, noting that PEM electrolysis is expensive due to high capital and operational costs, and emphasizes the need for research that balances efficiency with cost-effectiveness. The panel also touches on the role of artificial intelligence in characterizing and optimizing materials, and the importance of leveraging existing industrial parks and expertise to accelerate learning curves. Overall, the discussion underscores the need for technological innovation, local manufacturing, and strategic policies to position Brazil as a leader in the green hydrogen economy.
