Innovative Electrochemical Cell Converts Captured CO2 into Green Fuel

Researchers at Tokyo Metropolitan University have developed a new cell that efficiently transforms carbon dioxide into formate, addressing key challenges in carbon capture technology.

• The new electrochemical cell features a polymer electrolyte membrane and a porous cellulose ester layer, enhancing selectivity and efficiency in converting bicarbonate ions to formate ions.
• This technology offers an energy-efficient alternative to traditional methods that require pure, pressurized carbon dioxide, which are highly energy-intensive.
• The cell demonstrated a faradaic efficiency of 85%, meaning a high proportion of electrons were converted into formate rather than other byproducts.
• The cell operated continuously for over 30 hours, achieving nearly complete conversion of bicarbonate to solid, crystalline formate fuel.
• Formate fuel, which is non-combustible and stable for long periods, presents a practical and durable green energy solution, with potential applications ranging from home power units to industrial scales.
