“…There are also a number of conclusions that can be drawn based on the empirical analysis conducted in this work, namely a comparative assessment with other Middle Eastern countries. As of the year 2022, the Middle East is in the lowest region in terms of CCS projects [ 56 ]. This should not be confused with the shear amount of carbon captured, as the region has 11 CCS operational projects located in Saudi, Qatar, and the Emirates, which are responsible for 10% of global CO 2 captured annually (capacity extending 3.8 Mt per annum in some cases), i.e., double that of Europe.…”

The rapid growth and urbanization rate, coupled with hot climate and scarce rainfall, makes it essential for a country like Kuwait to have several power and desalination plants with high-generating capacity. These plants are entirely reliant on burning fossil fuels as a source of thermal energy. These plants are also universally accepted to be the largest CO2 emitters; hence, they present a potential for carbon capture and storage (CCS). Having established the suitability of the existing conditions for post-combustion CCS, a techno-economic-based feasibility study, which took into consideration local power generation technologies and economic conditions, was performed. Relying on fifteen case study models and utilizing the concept of levelized cost of electricity (LCOE), the statistical average method (SAM) was used to assess CCS based on realistic and reliable economic indicators. Zour power station, offering the highest potential CO2 stream, was selected as a good candidate for the analysis at hand. Heavy fuel oil (HFO) was assumed to be the only fuel type used at this station with affixed price of USD 20/barrel. The analysis shows that the internal rate of return (IRR) was about 7%, which could be attributed to fuel prices in Kuwait and governmental support, i.e., waived construction tax and subsidized workforce salaries. Furthermore, the net present value (NPV) was also estimated as USD 47,928 million with a 13-year payback period (PBP). Moreover, 1–3% reductions in the annual operational cost were reflected in increasing the IRR and the NPV to 9–11% and USD 104,085–193,945 million, respectively, and decreasing the PBP to 12–11 years. On the contrary, increasing the annual operational cost by 1% made the project economically unfeasible, while an increase of 3% resulted in negative IRR (−1%), NVP (−USD 185,458 million) and increased PBP to 30 years. Similarly, increasing the HFO barrel price by USD 5 resulted in negative IRR (−10%) and NVP (−USD 590,409); hence, a CCS project was deemed economically unfeasible. While the study considered the conditions in Kuwait, it is expected that similar results could be obtained for other countries with an oil-driven economy. Considering that around 62% of the fossil fuel blend in Kuwait is consumed by electricity and water generation, it is inevitable to consider the possibility and practicality of having a carbon network with neighboring countries where other oil-driven economies, such as Kingdom of Saudi Arabia and Iraq, can utilize a CCS-based mega infrastructure in Kuwait. The choice of Kuwait is also logical due to being a mid-point between both countries and can initiate a trading scheme in oil derivatives with both countries.

“…Collectively and in accordance with the Paris Agreement directives, there has been a worldwide effort towards the goal of CO 2 emissions abatement worldwide. Indeed, although not all of the proposed technologies for carbon dioxide mitigation are necessarily Paris-compatible and economically feasible in the long term [58], increased funding has been allocated for the deployment of several projects globally [4,[130][131][132]. In particular, in 2020, the USA government approved the US Energy Act, authorizing the allocation of ca.…”

“…In all, these efforts have led to the development of a total of 134 commercial facilities in operation and/or under construction worldwide, with an estimated total capacity of around 37 Mtonnes of CO 2 per year, the majority of which located in the United States. In any case, even more detailed information as well as further regional breakdown of the various CCS and CCU projects on a global scale can be found in [4,[130][131][132] and references therein.…”

“…At the same time, the most efficient technology is pre-combustion of coal or natural gas, as it is associated with a high CO 2 concentration, which favors the adsorption efficiency. Thus, it is a fully developed technology that is commercially deployed at industrial scale [132,133]. Additionally, although removal efficiency values are in general relatively high (i.e., more than 80%), in the case of CO 2 capture from power plant flue gases, they need to be amped up even further in order to improve the cost-effectiveness of the employed CCS/CCUS technology, since the eventual electricity cost can be increased up to 90% [134].…”

Recent Advances on CO2 Mitigation Technologies: On the Role of Hydrogenation Route via Green H2

et al. 2022

The increasing trend in global energy demand has led to an extensive use of fossil fuels and subsequently in a marked increase in atmospheric CO2 content, which is the main culprit for the greenhouse effect. In order to successfully reverse this trend, many schemes for CO2 mitigation have been proposed, taking into consideration that large-scale decarbonization is still infeasible. At the same time, the projected increase in the share of variable renewables in the future energy mix will necessitate large-scale curtailment of excess energy. Collectively, the above crucial problems can be addressed by the general scheme of CO2 hydrogenation. This refers to the conversion of both captured CO2 and green H2 produced by RES-powered water electrolysis for the production of added-value chemicals and fuels, which are a great alternative to CO2 sequestration and the use of green H2 as a standalone fuel. Indeed, direct utilization of both CO2 and H2 via CO2 hydrogenation offers, on the one hand, the advantage of CO2 valorization instead of its permanent storage, and the direct transformation of otherwise curtailed excess electricity to stable and reliable carriers such as methane and methanol on the other, thereby bypassing the inherent complexities associated with the transformation towards a H2-based economy. In light of the above, herein an overview of the two main CO2 abatement schemes, Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU), is firstly presented, focusing on the route of CO2 hydrogenation by green electrolytic hydrogen. Next, the integration of large-scale RES-based H2 production with CO2 capture units on-site industrial point sources for the production of added-value chemicals and energy carriers is contextualized and highlighted. In this regard, a specific reference is made to the so-called Power-to-X schemes, exemplified by the production of synthetic natural gas via the Power-to-Gas route. Lastly, several outlooks towards the future of CO2 hydrogenation are presented.

A novel defect‐engineered MOF (quasi ZrFum or Q‐ZrFum) was synthesized via a controlled thermal deligandation process and incorporated into a CO2‐philic 6FDA‐durene polyimide (PI) matrix to form Q‐ZrFum loaded MMMs. Defect‐engineered MOFs and fabricated MMMs were investigated in terms of their characteristic properties and separation performance. The incorporation of defects into the MOF structure increases the pore size and provides unsaturated active metal sites that positively affect CO2 molecule transport. After the deligandation process, the interfacial compatibility between the Q‐ZrFum particles and the PI matrix increases, which improves the mechanical strength of Q‐ZrFum loaded membranes. MMM containing 5 wt.% of defect‐engineered Q‐ZrFum exhibits excellent CO2 permeability of 1308 Barrer which increased by 99% compared to the pure PI membrane (656 Barrer) at a feed pressure of 2 bar. Moreover, CO2/CH4 and CO2/N2 selectivity reached 44 and 26.6 which increased by about 70 and 16%, respectively. This study emphasizes that defect‐engineered MOFs can be promising candidates for use as filler in the preparation of MMMs for the future development of membrane‐based gas separation applications.
