“…In theory, the pre-combustion route could offer a cheaper cost than that of post-combustion and oxyfuel combustion routes by 38-45 and 21-24%, respectively (Portillo et al 2019). However, due to the retrofitting of current facilities, this added costing and complexity to the set-up process have limited its commercialisation.…”

“…Thus, investigating new novel routes of air separation is quite important herein, such as ion-transport and oxygen-transport membranes along with chemical looping methods (Shin and Kang 2018;Martinez and Hesse 2016;Chen et al 2018a;Shi et al 2018). To resolve the problem associated with the energy needed for cryogenic air separation, oxygen-transport membranes were introduced, known as the mixed ionic-electronic conducting membrane (MIEC) (Portillo et al 2019;Kotowicz and Balicki 2014). Carbo et al reported that the inclusion of oxygen-transport membranes in oxyfuel combustion could reach an economic saving in the range of 19-50%, compared to that of post-combustion technology (Carbo et al 2009).…”

“…Currently, post-combustion technology is the most mature and widely used route among the three main routes of carbon capture and storage (Wienchol et al 2020;Wang et al 2011a). However, due to the dilution of CO 2 comes from the flue gas by N 2 from the air, this reduces the partial pressure of CO 2 and increases the additional cost in the electricity generation by approximately 60-70% for the new infrastructure or 220-250% for the retrofitting (Portillo et al 2019).…”

Human activities have led to a massive increase in $$\hbox {CO}_{2}$$ CO 2 emissions as a primary greenhouse gas that is contributing to climate change with higher than $$1\,^{\circ }\hbox {C}$$ 1 ∘ C global warming than that of the pre-industrial level. We evaluate the three major technologies that are utilised for carbon capture: pre-combustion, post-combustion and oxyfuel combustion. We review the advances in carbon capture, storage and utilisation. We compare carbon uptake technologies with techniques of carbon dioxide separation. Monoethanolamine is the most common carbon sorbent; yet it requires a high regeneration energy of 3.5 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Alternatively, recent advances in sorbent technology reveal novel solvents such as a modulated amine blend with lower regeneration energy of 2.17 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Graphene-type materials show $$\hbox {CO}_{2}$$ CO 2 adsorption capacity of 0.07 mol/g, which is 10 times higher than that of specific types of activated carbon, zeolites and metal–organic frameworks. $$\hbox {CO}_{2}$$ CO 2 geosequestration provides an efficient and long-term strategy for storing the captured $$\hbox {CO}_{2}$$ CO 2 in geological formations with a global storage capacity factor at a Gt-scale within operational timescales. Regarding the utilisation route, currently, the gross global utilisation of $$\hbox {CO}_{2}$$ CO 2 is lower than 200 million tonnes per year, which is roughly negligible compared with the extent of global anthropogenic $$\hbox {CO}_{2}$$ CO 2 emissions, which is higher than 32,000 million tonnes per year. Herein, we review different $$\hbox {CO}_{2}$$ CO 2 utilisation methods such as direct routes, i.e. beverage carbonation, food packaging and oil recovery, chemical industries and fuels. Moreover, we investigated additional $$\hbox {CO}_{2}$$ CO 2 utilisation for base-load power generation, seasonal energy storage, and district cooling and cryogenic direct air $$\hbox {CO}_{2}$$ CO 2 capture using geothermal energy. Through bibliometric mapping, we identified the research gap in the literature within this field which requires future investigations, for instance, designing new and stable ionic liquids, pore size and selectivity of metal–organic frameworks and enhancing the adsorption capacity of novel solvents. Moreover, areas such as techno-economic evaluation of novel solvents, process design and dynamic simulation require further effort as well as research and development before pilot- and commercial-scale trials.

“…Although oxy‐combustion can be performed in retrofitted facilities with minimal changes, it is necessary to incorporate an O 2 supplier unit to provide the oxidant stream. The cryogenic air separation unit (C‐ASU) is an alternative commercially feasible option for O 2 supply, but it incurs a high energy penalty (6–12% of efficiency drop compared to the conventional air‐fired combustion) and elevated costs . Oxygen transport membranes (OTMs) are envisaged as a promising alternative to the C‐ASU .…”

BACKGROUND Control of greenhouse gas emissions has become one of the most important challenges faced by humanity. Among the various approaches to mitigating CO2 emissions, carbon capture and storage (CCS) is considered one of the most promising clean coal options for the future because it can be implemented in the short and medium terms at the industrial scale. Among CCS techniques, oxy‐combustion offers advantages in using pure oxygen (O2) as a comburent, where in a flue gas composed mainly of CO2 and water vapor is generated. Cryogenic air separation is the only available technology that can provide the required amount of O2, but this process requires large amounts of energy and is costly, which make its large‐scales implementation difficult. RESULTS In this framework, oxygen transport membranes are being researched as an O2 supplier unit because they offer advantages from a techno‐economic view point. In the present work, the thermochemical stabilities of La0.6Sr0.4Co0.2Fe0.8O3 and Cobalt‐doped Ce0.9Gd0.1O were evaluated to obtain information on their behavior in oxy‐combustion atmospheres. Experiments were performed in a circulating fluidized bed boiler of a pilot plant using an experimental sampling train. Samples of the two materials were characterized by X‐ray diffraction, X‐ray fluorescence, infrared spectroscopy, Raman spectroscopy, scanning electron microscopy with energy‐dispersive X‐ray spectroscopy, and Brunauer–Emmett–Teller analysis. CONCLUSIONS The results revealed that both materials were susceptible to the presence of species that originated from flue gas, materials comprising the boiler and ducts, and coal ash, and that the CGO_Co material showed better performance than the other studied material. © 2020 Society of Chemical Industry

The combustion, exhaust-gas concentrations, and stability characteristics of premixed CO 2 -diluted oxy-propane (C 3 H 8 /O 2 /CO 2 ) flames were investigated computationally using large eddy simulations (LES) in a swirl-stabilized model gas-turbine combustor. The simulations were carried out for ranges of equivalence ratio (Φ: 0.26-0.80) and oxygen fraction (OF: 35%-60%) at a fixed bulk inlet velocity of 5.2 m/s. The results indicate that the reaction rates increase with the increase of Φ and OF. Flames of the same adiabatic flame temperature (T ad ) show similar macro-and flowfield-structures, in terms of flame shape, flow circulation, and temperature, and species distributions, irrespective of the values of Φ and OF. At higher T ad , the flames were observed to be more compact with reduced flame thickness and higher Damkohler number (Da). In all cases, Da > 1 were observed, indicating the dominance of reaction rate in oxy-propane flames than the diffusion rate. A secondary IRZ was also observed near the outlet of the combustor. Mixture composition and combustion temperature influence the CO concentration at the combustor exit. The highest CO emission was observed at 0.17 ppm for the flame with highest Φ and T ad , meanwhile no CO emission was seen for flames with high OF and low Φ among the studied cases. Highlights 1. Adiabatic flame temperature is a quantifying parameter for flame
