Anthropogenic carbon dioxide (CO2) emissions are the main driver of climate change, motivating the implementation of CO2 capture and utilization approaches. CO2 electrolysis offers a means to utilize CO2 and simultaneously store excess intermittent renewable energy. Despite tremendous promise, there are limited demonstrations of CO2 electrolysis beyond lab-scale. This thesis seeks to address barriers to scaling CO2 electrolysis systems and to their integration within larger systems. The first work couples CO2 electrolysis with alkaline electrolytes to better match the optimal anodic conditions wherein, with moderate pressurization, a record cathodic energy efficiency is obtained (Chapter 3). Focusing on the total electrolyzer electricity inputs, a low-resistance electrolyzer, capable of operating at industrially relevant pressures, demonstrates a record-high full cell energy efficiency for CO2 electrolysis (Chapter 4). To reduce the energy and capital costs of upstream CO2 purification, a simulated flue gas containing dilute CO2 and oxygen impurities is efficiently converted to multi-carbon products using moderate pressurization and a hydrophilic catalyst coating strategy (Chapter 5). Process simulations of the downstream purification processes are performed, demonstrating that CO2 removal from the electrolyzer tail gas, especially the anodic one, constitute the biggest energy penalty (Chapter 6). To integrate with large-scale process modelling, simultaneously integrating CO2 electrolyzers with upstream and downstream processes, a semi-empirical CO2 electrolyzer model is developed and validated against lab and pilot-scale experiments (Chapter 7). CO2 electrolysis is scaled by several orders of magnitude in the largest CO2 electrolysis pilot plant to date, in contention for the NRG COSIA Carbon XPRIZE (Chapter 8).
