“…6 There are currently several conversion reactions that can directly use flue gas as a reactant instead of pure CO 2 stream such as algae cultivation using light photosynthesis, 124 mineral carbonation using silicate minerals 125 or alkaline solution, 126 and CO 2 hydrogenation including CO 2 -to-methane and methanol production. [127][128][129] As for the CO 2 hydrogenation reactions, Iaquaniello et al, 130 explored the methanation reaction based on the direct application of natural gas-fired power plant flue gas assuming the absence of SO x and NO x , which can serve as both CCSU technology and renewable H 2 storage. The authors reported that some of the flue gas impurities such as N 2 and H 2 O play an important role in better temperature control and additional steam replacement, respectively, whereas the O 2 content needs to be removed as it leads to H 2 overconsumption through forming H 2 O exothermically.…”

Carbon dioxide (CO2) utilization technologies have emerged as a promising approach to address the direct and indirect consequences of climate change and the need for sustainable resource management. Those innovative technologies aim to capture and utilize CO2 by converting it into valuable products or directly using it as a chemical feedstock in various industries, thus, avoiding their release into the atmosphere. In this study, different CO2 utilization pathways including CO2 to chemicals and fuels, CO2 to building materials, CO2 to enhanced oil recovery (EOR), and CO2 to bio‐products are discussed in terms of their status ‐ economical, environmental, and technology readiness level performances. Moreover, various CO2 utilization pathways are comparatively analyzed considering their advantages and drawbacks, CO2 uptake potentials, and overall climate benefits. According to the comparison results, photocatalytic and electrochemical reduction of CO2 along with the bio‐fixation of CO2 are gaining more attention in the recent research and investigations from the energy intensity and environmental point of view, while EOR still dominant in terms of the scalability, maturity, and economical benefits. However, limitations of EOR related to the capacity, life cycle, and different geolocations, as well as the complexities of other mature approaches make room for emerging technologies to be more energy‐effective and environmentally friendly. Overall, most of the promising CO2 utilization techniques are either technologically immature or limited in scale to deploy globally. One of the main barriers to reusing CO2 is associated with the high cost of CO2‐based production and the low value of the CO2 market.This article is protected by copyright. All rights reserved.
