APPLICATIONS OF TECHNOLOGY:
- Reducing carbon dioxide electrochemically
- Producing renewable commodity chemicals and fuels
- Better gas transport than liquid electrolyte
- Scalable design
- Incorporates polymers with ability to transport multiple types of ions
Researchers at Cyclotron Road, a Department of Energy (DOE) Lab-Embedded Entrepreneurship Program at Lawrence Berkeley National Laboratory (Berkeley Lab), have developed a technology to electrochemically reduce reactants such as carbon dioxide.
The apparatus, a novel membrane electrode assembly, overcomes earlier barriers to electrochemical approaches by transporting reactants, such as carbon dioxide, to the catalyst surface as a gas, rather than in a liquid, for better transport and higher production rates. The conversion process occurs near room temperature and ambient pressure. The technology can be scaled easily, making it applicable to a range of input volumes.
