carbon capture and utilization (CCU) involves the capture and use of CO2 as a resource to create valuable products. The competitiveness of various CCU technologies has been investigated frequently resulting in a variety of economic feasibility studies and economic indicators. This study performs a tutorial review, in which practical guidance is given on the implementation of Techno-Economic Assessments (TEAs) for chemical CCU technologies. The tutorial review maps the differences in the methods and assumptions of economic feasibility studies for CCU technologies and advises how these studies can be improved in the future. A TEA framework, drafted by the CCU research community, is used as a benchmark in this review, to allow for objective comparisons between various economic feasibility studies. The four phases of an exhaustive TEA are (I) goal and scope, (II) data inventory, (III) calculation of indicators and (IV) interpretation. The tutorial review reveals that economic feasibility studies for chemical CCU technologies can and should be improved in various manners. Phases I and II are often skipped or incomplete. In Phase III, a very diverse indicator set is observed, which hampers comparability across CCU technologies. Phase IV, the interpretation of results, is often missing in the literature set or lacks thorough uncertainty and sensitivity analyses. The comparison with the TEA framework revealed the diversity in assumptions and methodological choices in the literature set. These findings suggest that future economic feasibility studies should be made in a more standardized way to improve both the quality and comparability of economic feasibility studies. Four improvements to the TEA framework are suggested: (i) focussing more on the impact of technical parameters in sensitivity analyses, (ii) adapting the assessment to the TRL of the technology, (iii) implementing ROA in the TEA and (iv) integrating an environmental assessment or LCA with the TEA.

Plasma-sorbent systems are a novel technology for single-stage carbon capture and utilization (CCU), where the plasma enables the desorption of CO2 from a sorbent and the simultaneous conversion to CO. In this study, we test the flexibility of a plasma-sorbent system in a single unit, specifically for sorption-enhanced dry reforming of methane (DRM). The experimental results indicate the selective adsorption of CO2 by the sorbent zeolite 5A in the first step, and CH4 addition during the plasma-based desorption of CO2 enables DRM to various value-added products in the second step, such as H-2, CO, hydrocarbons, and the byproduct H2O. Furthermore, our work also demonstrates that zeolite has the potential to increase the conversion of CO2 and CH4, attributed to its capability to capture H2O. Aside from the notable carbon deposition, material analysis shows that the zeolite remains relatively stable under plasma exposure.

carbon capture and utilization (CCU) is an emerging field proposed for emissions mitigation and even negative emissions. These potential benefits need to be assessed by the holistic method of Life Cycle Assessment (LCA) that accounts for multiple environmental impact categories over the entire life cycle of products or services. However, even though LCA is a standardized method, current LCA practice differs widely in methodological choices. The resulting LCA studies show large variability which limits their value for decision support. Applying LCA to CCU technologies leads to further specific methodological issues, e.g., due to the double role of CO2 as emission and feedstock. In this work, we therefore present a comprehensive guideline for LCA of CCU technologies. The guideline has been development in a collaborative process involving over 40 experts and builds upon existing LCA standards and guidelines. The presented guidelines should improve comparability of LCA studies through clear methodological guidance and predefined assumptions on feedstock and utilities. Transparency is increased through interpretation and reporting guidance. Improved comparability should help to strengthen knowledge-based decision-making. Consequently, research funds and time can be allocated more efficiently for the development of technologies for climate change mitigation and negative emissions.

carbon capture and utilization (CCU) has been proposed as a sustainable alternative to produce valuable chemicals by reducing the global warming impact and depletion of fossil resources. To guarantee that CCU processes have environmental advantages over conventional production processes, thorough and systematic environmental impact analyses must be performed. Life-Cycle Assessment (LCA) is a robust methodology that can be used to fulfil this aim. In this context, this article aims to review the life-cycle environmental impacts of several CCU processes, focusing on the production of methanol, methane, dimethyl ether, dimethyl carbonate, propane and propene. A systematic literature review is used to collect relevant published evidence of the environmental impacts and potential benefits. An analysis of such information shows that CCU generally provides a reduction of environmental impacts, notably global warming/climate change, compared to conventional manufacturing processes of the same product. To achieve such environmental improvements, renewable energy must be used, particularly to produce hydrogen from water electrolysis. Importantly, different methodological choices are identified that are being used in the LCA studies, making results not comparable. There is a clear need to harmonize LCA methods for the analyses of CCU systems, and more importantly, to document and justify such methodological choices in the LCA report.

CLIMATIC CHANGE 2021年第1-2期166卷 1-20页

作者： Lutzke, Lauren Arvai, Joseph Univ Southern Calif Dept Psychol 3620 S McClintock Ave Los Angeles CA 90089 USA Univ Southern Calif Wrigley Inst Environm Studies Los Angeles CA 90007 USA Decis Res Eugene OR USA

carbon capture and utilization (CCU) has been highlighted as one element of a climate mitigation strategy that aims to limit global warming. Yet, without broad consumer acceptance, there may not be a reliable end-market for CCU-based products, hindering the economic viability and potential mitigative benefits of CCU. Therefore, through an online survey of US adults, this study measured the influence of product type (carbonated beverages, plastic food storage containers, furniture made with foam or plastic, and shatterproof glass) and carbon capture method (Direct Air capture or point source capture) on a consumer's willingness to consume or use a CCU-based product. Compared to other products, participants were less accepting of carbonated beverages, particularly those containing carbon captured from point sources. At the same time, the majority of participants (approximately 69%) reported at least some openness to consuming or using a CCU-based product. Several other variables which also influenced consumer acceptance (and could inform future communication strategies surrounding CCU-based products) were identified.

carbon capture and utilization (CCU) is an emerging climate change mitigation technology. At this early stage of development, there are still major uncertainties about the extent to which CCU can help mitigate climate change due economic and technological challenges. This study focuses on an additional complication in the development and deployment of CCU: how the public perceives its benefits, risks, and acceptability. In a nationally representative study of U.S. adults (N =1200), we examined (1) overall support for CCU;(2) public expectations about CCU's effects on health, the economy, and climate change;and (3) whether perceptions vary depending on which aspects of CCU are discussed (general overview of CCU, proposed local facility, or using CCU-derived products). Using an oversample of Black, Hispanic/Latino, and Asian American participants (n = 471, total N = 1671), we also explored how beliefs differed across race/ethnicity and gender as well as the influence of psychological traits of environmentalist identity and aversion to tampering with nature. We found that the U.S. public had moderately positive views of CCU overall, with important nuances. First, people were less positive about CCU facilities in their home communities than they were about the idea of CCU in general or about products made with CCU. Second, people believed CCU would benefit the economy more than health or climate change. Third, individual differences in demographics and psychological traits matter for perceptions: (1) women were more wary of CCU than men, and (2) while White participants had more positive views about CCU the more they identified as environmentalists, the same was not always true for Hispanic or Black respondents. The study, thus, reveals the nuanced ways in which different American audiences may respond to CCU proposals.

As the rate of carbon dioxide emissions directly contributes to global warming, there have been various attempts in the research community to develop novel pathways that mitigate and control this impact. These outcomes of their research are primarily documented in articles, and finding effective solutions necessitates the ability to scan the scientific literature and extract relevant information. In this study, we propose a large language model (LLM), CCU-Llama, for extracting knowledge about carbon capture and utilization (CCU). To create CCU-Llama, employ Llama-2 LLM and apply pretraining and transfer-learning techniques using CCU research articles sourced from the Elsevier database via API. Thorough preprocessing eliminates irrelevant content from the extracted article text. This proposed LLM model performs two major tasks: (i) the CCU-technology potential knowledge extraction task, which provides information about technology and its impact using sentence pair extraction and sentence pairing classification with accuracy of 0.835 and 0.779, respectively, and (ii) creating an interface like a chatbot with a visualization task that can respond to any query related to CCU. CCU-Llama outperforms ChatGPT in F1-score and IFnumeric with scores of 0.7366 and 0.301, respectively, compared to ChatGPT's scores of 0.6822 and 0.003. This work would help to rapidly analyze the number of carbon source capture and utilization applications. Ultimately, extracted knowledge about CCU technologies can be used to guide the transition toward the goal of net-zero greenhouse gas emissions.

Cyanobacteria are photosynthetic bacteria that can directly convert CO2 into several bio-products for industrial use, such as alcohols and diols, terpenes, acids, and sugars. However, some of these compounds are either produced in low amounts or are absent in cyanobacteria, and thus strain development is required to achieve optimal production of these bio-products for industrial applications. Metabolic engineering has been applied to modify cyanobacteria for enhanced production of value-added compounds. In this review, we have elucidated metabolic engineering of various pathways with the yield and productivity of the desired products. We have also described recent overall strategies in advanced metabolic engineering.

The EU low-carbon economy aims to reduce the level of CO2 emission in the EU to 80% by 2050. High efforts are required to achieve this goal, where successful CCU (carbon capture and utilization) technologies will have a high impact. Biocatalysts offer a greener alternative to chemical catalysts for the development of CCU strategies since biocatalysis conforms 10 of the 12 principles of green chemistry. In this study, a multienzymatic system, based on alcohol dehydrogenase (ADH), pyruvate decarboxylase (PDC), and lactate dehydrogenase (LDH), that converts CO2 and ethanol into lactic acid leading to a 100% atom economy was studied. The system allows cofactor regeneration, thus reducing the process cost. Through reaction media engineering and enzyme ratio study, the performance of the system was able to produce up to 250 mu M of lactic acid under the best conditions using 100% CO2, corresponding to the highest concentration of lactic acid obtained up to date using this multienzymatic approach. For the first time, the feasibility of the system to be applied under a real industrial environment has been tested using synthetic gas mimicking real blast furnace off-gases composition from the iron and steel industry. Under these conditions, the system was also capable of producing lactic acid, reaching 62 mu M.

Modeling and simulation of a reactive separation system for carbon capture and utilization in biogas streams

CHEMICAL ENGINEERING AND PROCESSING-PROCESS INTENSIFICATION 2020年 156卷

An effective energy storage approach, such as Power-to-Gas, is essential to provide the grid with a steady supply of power generated by renewable sources. In a Power-to-Gas concept, excess renewable energy is stored in the form of H-2 which, in turn, can react with CO2 from sources such as biogas to be converted into CH4 and generate Renewable Natural Gas (RNG). Methanation however, is an exothermic and equilibrium-limited reaction which suffers from poor heat management when carried-out in conventional packed-bed reactors. Additionally, unreacted H-2 mixed with CH4 has to be removed before the RNG is injected into the pipeline. To improve the methanation of biogas, two commercial high temperature reactive separation systems have been studied numerically in this work: (i) an extractor/distributor membrane reactor employing a carbon molecular sieve membrane;(ii) a distributor membrane reactor using a palladium membrane. Both configurations have been shown to considerably reduce the content of CO2 and H-2 in the resulting RNG and, hence, the post-processing efforts needed as compared to a packed-bed reactor operating under the same conditions.
