“…The heat consumption of FGCC is assumed to be between 2.4 and 2.8 GJ/t CO 2 (106–123 kJ/mol) which is a common range for commercial liquid amine‐based systems 11,12 . We further assume specific carbon content of 0.16 Mt C for each TWh th of energy in woody biomass, following previous analyses, 60,61 97% of which may be captured in a BECCS plant.…”

Direct Air Capture (DAC) is a negative emission technology that can remove up to 10–20 Gt of CO2 per year. However, to achieve this potential, DAC systems must be coupled to suitable locally available energy sources and sited near geological storage. This study explores the potential of low‐carbon energy sources to supply power and heat to the DAC process in a dedicated, self‐sufficient system tailored for each energy source. Solar, geothermal, woody biomass, wind, and nuclear energy sources are assessed for their global energy supply potential and possible land use requirements. While the options differ in area requirement and regional efficacy, we estimate that all the regionally specific technologies considered can supply energy to achieve significant removal of carbon dioxide from the atmosphere globally. The amount of energy physically available from solar, offshore wind, and woody biomass converts to a removal potential of 160–971, 45–150, and 2–5 Gt CO2/year, respectively. Thus, negative emission targets can be reached by utilizing a moderate fraction of the overall potential of several different low‐carbon energy sources for DAC while the magnitude of the potential changes significantly according to the source of energy. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…There are four main CO 2 capture technologies, that is, chemical absorption, adsorption, membrane separation and cryogenic distillation. Chemical absorption is the most researched, implemented and commercialized option among the named separation technologies, especially in post‐combustion capture due to its distinct advantages 11,14,29–35 . These advantages include excellent CO 2 absorption efficiency of 80–100%, adaptability to low‐pressure conditions and capability to produce high purity CO 2 (up to 99%) 2,12–14,31,32,34,36–41 .…”

Review of carbon capture absorbents for CO₂utilization

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. Carbon capture and storage (CCS) is preferred over carbon conversion and utilization (CCU) due to its lower operating costs and higher CO2 reduction capability. Nevertheless, CO2 utilization has the potential to be more economical if value‐added products are produced. This highlights the importance of assessing CO2 utilization routes and alternatives in carbon management. This review paper aims to evaluate the carbon utilization potential of major CO2‐capturing absorbents including amine, hydroxide, ionic liquid, amino acids and carbonate absorbents. All absorbents show potential application for CO2 utilization except for ionic liquids (ILs) due to their unclear CO2 capture mechanisms. Absorbents that require a desorption process for CO2 utilization include MEA, MDEA, K2CO3 and Na2CO3 due to their high absorption capacity. Industries have utilized the desorbed CO2 as chemical feedstocks, enhanced oil recovery (EOR) and mineral carbonation. For hydroxide absorbents and CaCO3, desorption of CO2 is unnecessary as the absorbed CO2 can be directly utilized to produce construction materials. Apart from that, the incorporation of advanced technologies and business models introduced by the fourth industrial revolution are plausible considerations to accelerate the development of carbon capture technologies. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

As a new type of solvent, ionic liquids (ILs) are considered to be promising in the field of CO 2 capture. Due to the lack of typical industrial process cases, it is necessary to conduct a life cycle assessment (LCA) to determine the environmental performance of IL-based chemical processes and explore possible improvements. In this work, the LCA method is used to evaluate the carbon capture and storage (CCS) process from the solvent production stage to the use stage with [bmim][Tf 2 N] IL as the CO 2 absorption solvent. The effects of different processes and CO 2 capture ratios on the environmental performance of CCS-IL are also explored, and some suggestions for improvement are provided. The LCA results show that the main environmental impact stage of the CCS-IL process is the solvent production stage, which has effects that are far beyond the environmental impact of the solvent use stage, and anion production is the main factor. The LCA results of the solvent use process show that optimization of the CCS-IL process can reduce the environmental burden of the solvent use stage. From the perspective of the global environment, the introduction of waste heat resources into the CCS process will have a positive impact on the environment. The sensitivity analysis shows that reducing the CO 2 capture ratio can reduce the environmental burden of the CCS-IL process, but it requires factories to bear a higher carbon tax and environmental responsibility. LCA analysis will help decision makers to further understand the IL-based chemical process and conduct accurate evaluations.
