“…In the design of the CO 2 capture process, the absorption method is usually used as the benchmark for comparison. According to the simulation results of Lee et al [ 54 ] for a 500 MW power plant, the capture cost of the traditional Selexol process for CO 2 treatment is 21 $/t CO 2 , which is close to the goal of 20 $/t CO 2 of DOE [ 55 ]. It can be seen from Figure 17 that under the condition of keeping the capture rate 90%, even if the CO 2 purity rises to 99%, the cost is about 13.57$/t CO 2 , which shows that the cost of membrane technology is better than that of absorption technology.…”

Membrane separation technology for CO2 capture in pre-combustion has the advantages of easy operation, minimal land use and no pollution and is considered a reliable alternative to traditional technology. However, previous studies only focused on the H2-selective membrane (HM) or CO2-selective membrane (CM), paying little attention to the combination of different membranes. Therefore, it is hopeful to find the optimal process by considering the potential combination of H2-selective and CO2-selective membranes. For the CO2 capture process in pre-combustion, this paper presents an optimization model based on the superstructure method to determine the best membrane process. In the superstructure model, both CO2-selective and H2-selective commercial membranes are considered. In addition, the changes in optimal membrane performance and capture cost are studied when the selectivity and permeability of membrane change synchronously based on the Robeson upper bound. The results show that when the CO2 purity is 96% and the CO2 recovery rate is 90%, the combination of different membrane types achieves better results. The optimal process is the two-stage membrane process with recycling, using the combination of CM and HM in all situations, which has obvious economic advantages compared with the Selexol process. Under the condition of 96% CO2 purity and 90% CO2 recovery, the CO2 capture cost can be reduced to 11.75$/t CO2 by optimizing the process structure, operating parameters, and performance of membranes.

“…H 2 can also be used as a promising solution for a multi-sectorial decarbonization as it allows to link between the green and blue H 2 production systems and the other energy sectors (industry, transport, and natural gas system) (Burandt et al, 2019;Helgeson and Peter, 2020;Tlili et al, 2020). The production of large-scale green and blue H 2 will more energy efficient and economical viable if integrated processes are applied (Gençer and Agrawal, 2017;Lee et al, 2019;Spallina et al, 2019;Mosca et al, 2020).…”

Low carbon hydrogen can be an excellent source of clean energy, which can combat global climate change and poor air quality. Hydrogen based economy can be a great opportunity for a country like Qatar to decarbonize its multiple sectors including transportation, shipping, global energy markets, and industrial sectors. However, there are still some barriers to the realization of a hydrogen-based economy, which includes large scale hydrogen production cost, infrastructure investments, bulk storage, transport & distribution, safety consideration, and matching supply-demand uncertainties. This paper highlights how the aforementioned challenges can be handled strategically through a multi-sector industrial-urban symbiosis for the hydrogen supply chain implementation. Such symbiosis can enhance the mutual relationship between diverse industries and urban planning by exploring varied scopes of multi-purpose hydrogen usage (i.e., clean energy source as a safer carrier, industrial feedstock and intermittent products, vehicle and shipping fuel, and international energy trading, etc.) both in local and international markets. It enables individual entities and businesses to participate in the physical exchange of materials, by-products, energy, and water, with strategic advantages for all participants. Besides, waste/by-product exchanges, several different kinds of synergies are also possible, such as the sharing of resources and shared facilities. The diversified economic base, regional proximity and the facilitation of rules, strategies and policies may be the key drivers that support the creation of a multi-sector hydrogen supply chain in Qatar.

“…CO 2 dominates the landscape of greenhouse gas emissions, comprising a substantial 85%, with fossil fuel consumption singularly responsible for nearly 58.8%. The confluence of an expanding global populace and the currents of globalization have precipitated a noteworthy surge in the utilization of fossil fuels across many nations. − In response to the formidable challenge posed by uncontrollable emissions, the proposition of carbon neutrality has emerged as a strategic approach. Carbon neutrality constitutes attaining a net zero CO 2 emission state, meticulously achieved by maintaining a harmonious equilibrium between carbon emissions and carbon absorption.…”

Carbon capture, utilization, and storage (CCUS) technology plays a pivotal role in China's "Carbon Peak" and "Carbon Neutrality" goals. This approach offers low-carbon, zero-carbon, and even negative-carbon solutions. This paper employs bibliometric analysis using the Web of Science to comprehensively review global CCUS progress and discuss future development prospects in China. The findings underscore it as a prominent research focus, attracting scholars from both domestic and international arenas. China notably leads the global landscape in terms of research paper output, with the Chinese Academy of Sciences holding a prominent position in total published papers. The research predominantly centers on refining geological storage techniques and optimizing oil and gas recovery rates. Among the CCUS pathways, enhanced oil recovery technology stands out due to its relative maturity and commercial applicability, particularly within the conventional oil and gas reservoirs. The application potential of enhanced gas recovery technology, especially in the Sichuan and Ordos Basins in China, necessitates robust research and demonstration efforts. Within China's current energy landscape, "Blue Hydrogen" emerges as the primary solution for hydrogen production in conjunction with CCUS technology. The underground coal gasification approach holds significant promise as a hydrogen production avenue, albeit with inherent ecological and environmental challenges tied to geological storage that require meticulous consideration. The establishment of effective risk identification and evaluation methodologies for geological storage is imperative. The trajectory ahead involves a strategic convergence of policy, technology, and market dynamics to enhance China's CCUS policy framework, legislative framework, standardization initiatives, and pioneering technological advancements. These collective efforts converge to outline an exclusive development pathway in China. This study assumes a pivotal role in accelerating CCUS technology research and deployment, enhancing oil and gas recovery efficiency, and ultimately realizing the overarching goals of a "Dual Carbon" future.
