Opportunity:
Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its Gas Diffusion Electrodes for CO2 electrolysis in Cation Free Systems.
Background:
During CO2 electrolysis, cations need to arrive at the cathode to catalyze the chemical transformations and allow for highly selective carbon dioxide (CO2) reduction. While salts are required to drive efficient electrolysis, they also lead to failure modes. Salts crossing over from the anode to cathode increase the electro-osmotic drag of water which can induce flooding, or if sufficient cations reach the cathode, the concentration can exceed the solubility limit typically in the flow field due to convective drying leading to precipitation and gas blockage.
To overcome the need for salts at the cathode, existing strategies include fixed charge at the cathode surface using polymer electrolytes. Currently, systems that use deionized (DI) water fed systems require a forward bias bipolar membrane. Forward bias bipolar membranes are at a low technology readiness level (TRL) due to the recombination of liquids and gases at the membrane interface leading to mechanical failure and require further research to develop durable systems.
To date, state-of-the-art systems using DI water anolytes can still only achieve up to 80% selectivity for CO at 200 mA cm-2 which is insufficient for commercialization. There is a need for a more selective design to reduce CO2 to CO, a building block for many chemical compounds.
