ABSTRACTNanoporous metal-organic framework (MOF) materials are strong candidates for energy efficient carbon capture and storage (CCS) technologies. A total of ∼20,000 hypothetical MOFs were ab initio screened for CO2 adsorption using grand canonical Monte-Carlo (GCMC) simulations. Novel radial distribution function (RDF) scores were modified for periodic systems to predict the CO2 adsorption of MOFs using chemoinformatic models. The test set predictions yielded accuracies of 0.76 and 0.85 at 0.1 bar and 1 bar, respectively. The models were used to screen a large database for high performing MOFs and the top 100 structures were successfully validated by GCMC simulations. The chemoinformatic predictors of the CO2 adsorption of MOFs are available online at http://titan.chem.uottawa.ca/woolab/MOFIA/#carbondioxide.

Metal-Organic Frameworks (MOF) have been identified as highly efficient nanoporous adsorbents for CO2 storage. In particular, Mg-MOF-74 has been shown to promise exceptionally high CO2 sorption. Although several studies have reported adsorption isotherms of CO2 in Mg-MOF-74, the effect of inter-crystalline spacing in Mg-MOF-74 on the sorption of CO2 has not been addressed. These effects have been shown to be profound for a quadrupolar molecule like CO2 in the case of silicalite (Phys. Chem. Chem. Phys. 22 (2020) 13951). Here, we report the effects of inter-crystalline spacing on the adsorption of CO2 in Mg-MOF-74, studied using grand canonical Monte Carlo (GCMC) simulations. The inter-crystalline spacing is found to enhance adsorption at the crystallite surfaces. Larger inter-crystalline spacing up to twice the kinetic diameter of CO2 results in higher adsorption and larger crystallite sizes suppress adsorption. Magnitudes of the inter-crystalline space relative to the kinetic diameter of the adsorbed fluid and the surface to volume ratio of the adsorbent crystallites are found to be important factors determining the adsorption amounts. The results of this study suggest that the ideal Mg-MOF-74 sample for CO2 storage applications should have smaller crystallites separated from each other with an inter-crystalline space of approximately twice the kinetic diameter of CO2.

This article deals with review of technical and economic aspects of Carbon Capture and Storage. Since the late 1980s a new concept is being developed which enables to make use of fossil fuels with a considerably reduced emission of carbon dioxide to the atmosphere. The concept is often called ‘Carbon Capture and Storage’ (CCS). CCS technologies are receiving increasing attention, mainly for their potential contribution to the optimal mitigation of carbon dioxide emissions that is intended to avoid future, dangerous climate change. CCS technologies attract a lot of attention because they could allow “to reduce our carbon dioxide emissions to the atmosphere whilst continuing to use fossil fuels”. CCS is not a completely new technology, e.g., the United States alone is sequestering about 8.5 MtC for enhanced oil recovery each year. Today, CCS technologies are widely recognised as an important means of progress in industrialized countries.

This paper studies the effect of policy incentives on investment strategies of carbon capture and storage (CCS) technologies. We establish CCS investment models based on real options theory for investment value evaluation of CCS, which consider CO2price, policy incentives and different CCS technologies that include the old existing CCS technology and the new one. We evaluate CCS investment option values and calculate the change of CCS investment values and thresholds due to the variation of CO2price and policy incentives. We conclude that the optimal strategy is investing in the new CCS technology when there are enough policy incentives, otherwise, it is optimal to firstly invest in the old existing CCS technology and then upgrade to the new one.

Abstract Carbon Capture and Storage (CCS) technologies are a perspective solution to reduce the amount of CO2 emissions. One of promising methods is Ca-looping, which is based on carbonation and calcination reactions. During both of these processes, especially calcination, high temperatures (650-950°C) are required. This means high demands on the corrosion resistance of equipment materials. Therefore, we carried out a study to suggest materials with suitable properties for calciner construction, which have to be particularly heat resistant: stainless steels (AISI 304, AISI 316L and AISI 316Ti) and nickel alloys (Inconel 713, Inconel 738, Incoloy 800H). A special device simulating calciner environment was built for this purpose. Chosen materials were tested in temperature 900°C, atmospheric pressure and gaseous environment with composition that can be possible in a calciner. The surfaces of materials were evaluated to determine composition and properties of formed oxide layers. High temperature oxidation was observed on all tested materials and oxide exfoliation occurred on some of tested materials (304, 316L).

Global concern about climate change caused by anthropogenic activities, such as the large scale use of fossil fuels as major energy sources for domestic and industrial application, which on combustion give off carbon dioxide (CO2) into the atmosphere. Deforestation is also reducing one of the natural sinks for CO2. These anthropogenic activities have led to an increase in the concentration of CO2 in the atmosphere and have thus resulted in the warming of the earth’s surface (Global Warming), droughts, melting of ice caps, and loss of coral reefs. Carbon capture and storage (CCS) and other variety of emerging technologies and methods have been developed. These technologies and methods are reviewed in this article. Keywords: Global warming, carbon capture and storage, amine-based absorbents, Metal-Organic Frameworks
