A team of researchers led by Arizona State University are developing a reliable and energy efficient carbon dioxide capture system to mitigate waste carbon dioxide and emissions. This innovative device uses less energy than commercial carbon capture systems and easily retrofits at existing facilities.
This device employs an electrochemical cell to capture CO2 at the cathode, transport it across the cell and release it at the anode.
Key innovations of this technology include:
- Electrochemical assist based on novel chemistry
- The device is not oxygen sensitive
- Runs on electricity
- Able to transport up concentration and pressure gradients
- Continuous operation based on fuel cell gas diffusion electrodes
- Low capital cost
