Benchmarking Performance Indices of Electrochemical CO₂ Reduction to Ethylene Based on Prospective Life Cycle Assessment for Negative Emissions.

ABSTRACT: To mitigate global warming to the most ambitious targets, it is necessary to remove CO₂ from the atmosphere and reduce fossil fuels use. The electrochemical conversion of CO₂ to ethylene (C₂H₄) as a basic chemical is a promising technology that meets both requirements; however, its life cycle CO₂ emissions remain inconclusive because of varying assumptions in the performance indices. This study aimed to set benchmarks for the four most sensitive indices to achieve -0.5 t-CO₂/t-C₂H₄ by calculating net greenhouse gas (GHG) emissions through a prospective life cycle assessment of a model system including CO₂ capture, CO₂ enrichment, electrochemical conversion, CO₂ recycling
