Abstract

Electrochemically mediated CO₂ capture (EMCC) is a novel carbon capture technology. Despite its great potential, EMCC encounters technical and economic challenges. The Process Systems Engineering (PSE) methods and tools have potential to bridge the gap and overcome some obstacles in EMCC. This mini review offers an overview of innovations, opportunities, and challenges in EMCC from a multiscale PSE perspective. First, a brief introduction of different types of EMCC implementations is provided. Next, a thermodynamic model is proposed to analyze the impact of functional molecules (electrolyte), microstructure of electrode surface and cell structures on the system’s performance. Then, a multi-scale analysis is performed to examine the system across molecular-, meso-, unit-, and process-scales, with the potential applications of PSE methods explored. This study also shows that the EMCC technology can be further promoted by learning the experience from applying PSE methods to the flow battery and electrochemical reduction processes.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
