Researchers at Tokyo Metropolitan University have developed a groundbreaking industrial process to convert bicarbonate solution, derived from captured carbon, into formate solution, a sustainable green fuel. Published in the journal EES Catalysis, the study introduces a novel electrochemical cell with a polymer electrolyte membrane and a porous layer that facilitates the in-situ generation of carbon dioxide from reactive carbon capture. The cell overcomes challenges with traditional gas-fed processes and achieves results comparable to energy-intensive methods. The global focus on carbon capture technology to combat climate change has raised questions about the utilization of captured carbon dioxide. The new electrochemical cell aims to transform captured carbon into formate ions efficiently, which can be utilized in formate fuel cells to produce electricity. By allowing the production of formate ions directly from carbon dioxide dissolved in solutions like bicarbonate, the cell eliminates the need for pure gas, enhancing efficiency and sustainability. The Tokyo Metropolitan University researchers, led by Professor Fumiaki Amano, developed a cell that demonstrates exceptional selectivity in converting bicarbonate ions into formate ions. The innovative design with a porous membrane enables effective conversion of bicarbonate ions to formate ions, achieving high faradaic efficiency and operational longevity. The study's findings offer a promising solution for enhancing carbon capture and utilization processes, contributing to environmental sustainability. The team's achievement in improving the efficiency and selectivity of electrochemical cells signifies a significant advancement in green fuel technology. With the potential to address climate change challenges, the novel bicarbonate electrolyzer presents a practical and impactful solution for sustainable energy production. Funded by the Tokyo Metropolitan Government, this research paves the way for innovative developments in the field of electrochemistry and environmental conservation.
