Density functional simulations of CO2 adsorption an desorption rates as a function of CO2 pressure and temperature reveal that two-dimensional MXene materials of M2C formula (M = Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W) are able to adsorb, store, and activate CO2 molecules, with promising applications in carbon capture and storage strategies.

For significantly reducing greenhouse gas emissions, those from electricity generation should be negative by the end of the century. In this sense, bio-energy with carbon capture and storage (BECCS) technology in sugarcane mills could be crucial. This paper presents a technical and economic assessment of BECCS systems in a typical Brazilian sugarcane mill, considering the adoption of advanced—although commercial—steam cogeneration systems. The technical results are based on computational simulations, considering CO2 capture both from fermentation (released during ethanol production) and due to biomass combustion. The post combustion capture technology based on amine was considered integrated to the mill and to the cogeneration system. A range of energy requirements and costs were taken from the literature, and different milling capacities and capturing rates were considered. Results show that CO2 capture from both flows is technically feasible. Capturing CO2 from fermentation is the alternative that should be prioritized as energy requirements for capturing from combustion are meaningful, with high impacts on surplus electricity. In the reference case, the cost of avoided CO2 emissions was estimated at 62 €/t CO2, and this can be reduced to 59 €/t CO2 in case of more efficient technologies, or even to 48 €/t CO2 in case of larger plants.

The problem of global warming is a key challenge. One means to prevent climate change is to reduce the concentration of carbon dioxide in the atmosphere. This can be achieved using CO2 capture and storage (CCS) technology. Due to the relative novelty of the technology, low level of experience, and high risk of implementation, in practice society often displays a negative attitude towards CCS projects. Thus, it is necessary to develop a targeted strategy to popularize CO2 capture and storage technology. Based on an extensive literature review and the experience of implementation of CCS projects in different countries, this study demonstrates the necessity of applying the deficit, contextual, lay expertise, and public participation models to promote CCS technology. As a result, the factors influencing the choice of promotion tools are identified, and the measures to popularize CCS technology, depending on the stage of its implementation, are determined. Recommendations for the improvement of CCS public databases are developed. The methodologies used this study include case studies, system-oriented analysis, and stakeholder management tools.

This paper discusses and elicits consumer attitudes towards industrial carbon dioxide (CO2) capture and storage (ICCS) products and technologies. It presents a comprehensive review of the relevant research literature on consumer attitudes towards ICCS represented by the willingness-to-pay (WTP) and willingness-to-accept (WTA) negative externalities and outcomes of the carbon capture and storage (the so-called “not-in-my-backyard” (NIMBY) approach). In addition, it employs a concise empirical model that uses the data from the online questionnaire survey conducted in 7 European Union (EU) countries with and without ICSS sites. Our results demonstrate that having at least one ICCS site significantly reduces the WTA for the ICCS products and technologies. It is shown that further increase of ICCS sites, including those in the neighboring regions and countries, leads to the increase of negative consumer attitudes to the ICCS technologies and renewable energy policies. It becomes apparent that the majority of consumers are willing to support industrial CO2 capture and storage only if it happens far away from their dwellings. The outcomes of this paper might be informative for the EU local industries and policy-makers who are planning the location of ICCS sites and optimizing the public support for their endeavors. Moreover, they might be relevant for the stakeholders dealing with the threat of climate change and the necessity for the decarbonization of the economy.

Economic Comparison

Carbon Capture and Storage can either concern the removal of carbon as CO2 in flue gases (post-combustion option) or before its combustion in a Gas Turbine (pre-combustion option). Among the numerous CO2 capture technologies, amine scrubbing (MEA and MDEA), physical absorption (Selexol™ and Rectisol™) and H2 separator membrane reactors are investigated and compared in this study. In the pre-combustion options, the final fuel combusted in the GT is a rich-H2 fuel. Process simulations in ASPEN Plus™ showed that the case of H2 separation with Pd-based membranes has the greatest performance as far as the net efficiency of the energy system is concerned. The economic assessment reveals that the technology is promising in terms of cost of CO2 avoided, provided that the current high membrane costs are reduced.
