Porous metal electrodes enable efficient electrolysis of carbon capture solutions

Zishuai Zhang et al.

Summary: This study reports a bicarbonate electrolyser with a free-standing porous silver electrode, which is easier to fabricate and more hydrophilic than the commonly used composite carbon electrode. The electrolyser converts aqueous carbon capture solutions enriched with bicarbonate into carbon products and generates hydroxide for further reaction with waste CO2. The performance of this electrolyser is comparable to gas-fed CO2 electrolysers.

Continuum Model to Define the Chemistry and Mass Transfer in a Bicarbonate Electrolyzer

Eric W. Lees et al.

Summary: A validated model for quantifying the reaction chemistry and mass transfer processes in the catalyst layer and cation exchange membrane layer of a bicarbonate electrolyzer is reported in this study. The results show that an acidic membrane layer and a basic catalyst layer play a key role in forming CO at high rates. Modulating the properties of the catalyst and membrane layers can increase the rate of in situ CO2 generation and transport.

Gas diffusion electrodes and membranes for CO2 reduction electrolysers

Eric W. Lees et al.

Summary: This review explores material design strategies for controlling the transport of products and reactants in electrochemical reactors that convert CO2 emissions into chemicals and fuels, focusing on the design and development of gas diffusion electrodes (GDEs) and polymer electrolyte membranes tailored for the CO2 reduction reaction (CO2RR).

Comparative Techno-Economic and Life Cycle Analysis of Water Oxidation and Hydrogen Oxidation at the Anode in a CO2 Electrolysis to Ethylene System

Wenqin Li et al.

Summary: The study found that using anodic hydrogen oxidation instead of water oxidation can significantly reduce the capital cost of electrolyzer, and can reduce electricity demand by at least 50% in the current underdeveloped electrolyzer market. In the future scenario, to compete with the water oxidation system, hydrogen needs to be cheaper.

Cation-Driven Increases of CO2 Utilization in a Bipolar Membrane Electrode Assembly for CO2 Electrolysis

Kailun Yang et al.

Summary: By promoting alkali cation (K+) concentrations on the catalyst's surface, this study achieved a 3-fold increase in CO2 reduction selectivity in BPMEA system, reaching a CO Faradaic efficiency of 68%. Compared to anion exchange membrane, the cation-infused bipolar membrane system showed a 5-fold reduction in CO2 loss at similar current densities and exceeded the 50% CO2 utilization mark.

Downstream of the CO2 Electrolyzer: Assessing the Energy Intensity of Product Separation

Theo Alerte et al.

Summary: The study focuses on the downstream purification of ethylene produced from the electrochemical reduction of carbon dioxide, highlighting the energy-intensive CO2 removal step. Opportunities to reduce separation energy through improvements in ethylene selectivity, CO2 conversion, and CO2 crossover are identified, emphasizing the need for new, efficient separation processes tailored to CO2 electrolyzer outlet streams.

Operando cathode activation with alkali metal cations for high current density operation of water-fed zero-gap carbon dioxide electrolysers

B. Endrodi et al.

Summary: Precipitates that form in the cathode of continuous-flow CO2 electrolysers hinder their long-term operation, but the alkali metals they are formed from actually boost activity. Researchers address this dichotomy by periodically infusing the cathode with alkaline cations, enabling the electrolyser to operate stably and efficiently for extended periods.

Single Pass CO2 Conversion Exceeding 85% in the Electrosynthesis of Multicarbon Products via Local CO2 Regeneration

Colin P. O'Brien et al.

Summary: The CO2 reduction reaction (CO2RR) provides an opportunity to consume CO2 and produce desirable products, but the alkaline conditions required often lead to loss of input CO2 to bicarbonate and carbonate, limiting the conversion of CO2 to multicarbon products. This study found that cation exchange membranes (CEMs) and bipolar membranes (BPMs) were not ideal for providing locally alkaline conditions, but the development of a permeable CO2 regeneration layer (PCRL) allowed for a more efficient CO2 conversion process with limited CO2 crossover.
