CO2 Capture and Utilization for Fuel Synthesis

Abstract

CO<inf>2</inf> capture and utilization are effective techniques to use CO<inf>2</inf> for different purposes to reduce the impact of CO<inf>2</inf> emission on the environment. Two main sectors that dominate the CO<inf>2</inf> emission are electricity and heat production and transport. The concept of carbon capture, utilization, and storage (CCUS) for renewable fuel synthesis contributes to decreasing CO<inf>2</inf> emission; besides, the CCUS provides to produce renewable fuel to be used in the sectors. There have been many recent academic and industrial research efforts to implement CCUS into heat, power, and transport systems. Although this concept shows very good performance in terms of environment, there is still very low knowledge about the thermodynamic performance of the process employed in this concept. The mathematical modeling approaches are an effective tool to understand the performance under variable working conditions. In this chapter, a brief introduction to the concepts of CO<inf>2</inf> capture, separation, and utilization is presented. The basic mathematical modeling approaches to be applied for CO<inf>2</inf> capture and separation techniques are discussed systematically. Moreover, two main components, which are membrane reactor and CO<inf>2</inf> electrolyzer, are considered in this chapter for fuel synthesis through CO<inf>2</inf> utilization. © 2024 Elsevier B.V., All rights reserved.
