Researchers at Tokyo Metropolitan University have developed a groundbreaking electrochemical cell that converts bicarbonate, derived from captured carbon dioxide, into formate, a potent green fuel. This innovation could be a major breakthrough in carbon capture and utilization technology.
The new electrochemical cell uses reactive carbon capture to directly produce formate ions from dissolved CO2 in solutions like bicarbonate. This approach eliminates the need for pure CO2 and simplifies the conversion process. The cell achieves an 85% faradaic efficiency at high currents, making it a promising alternative solution.
According to the researchers, carbon capture and utilization is essential for achieving a carbon-neutral or negative emission future. However, the challenge of what to do with captured carbon dioxide remains an open question. This innovative technology provides a potential answer by converting CO2 into useful chemicals and fuels.
The team’s achievement has significant implications for reducing carbon emissions and combating climate change. As the researchers highlighted, “Carbon capture and utilization to convert atmospheric CO2 into useful chemicals and fuels is essential for achieving a carbon-neutral or negative emission future.”
