“…The latter have been used successfully for DMC/MeOH separations as well as two-step distillation–pervaporation separations in DEC synthesis from EtOH . Of course, all of these separation methods will have an associated energy cost for each cycle that will depend on the method chosen, concentration of the components, separation efficiency, and scale applied as previously investigated. − Which of these technologies may prove viable for application will depend on a number of additional factors that are beyond the scope of this work (cost, lifetime, etc. ), and a careful evaluation of compatibility with the reaction conditions and kinetics which are not considered in this thermodynamic analysis.…”

Equilibrium conversions for the direct condensation of MeOH and EtOH with CO 2 to give dimethyl- and diethyl carbonate, respectively, have been calculated over a range of experimentally relevant conditions. The validity of these calculations has been verified in both batch and continuous flow experiments over a heterogeneous CeO 2 catalyst. Operating under optimized conditions of 140 °C and 200 bar CO 2 , record productivities of 235 mmol/L·h DMC and 241 mmol/L·h DEC have been achieved using neat alcohol dissolved in a continuous flow of supercritical CO 2 . Using our thermodynamic model, we show that to achieve maximum product yield, both dialkyl carbonates and water should be continuously removed from the reactor instead of the conventionally used strategy of removing water alone, which is much less efficient. Catalyst stability rather than activity emerges as the prime limiting factor and should thus become the focus of future catalyst development.

“…However, practitioners must make many assumptions, for which they must involve subject matter experts. The R&D community used process simulation already for a large variety of CCU technologies, such as the individual conversions of CO 2 to CO (van Bavel et al, 2020), methanol (Pérez-Fortes et al, 2016bBlumberg et al, 2017), formic acid (Pérez-Fortes et al, 2016a), DME (Michailos et al, 2019;Ostovari et al, 2020) or carbonates (Ostovari et al, 2020) and the combination of individual conversion steps to value chains for chemicals (Kätelhön et al, 2019;Roh et al, 2019;Lee et al, 2021), and plastics (Meys et al, 2021).…”

Life-Cycle and Techno-Economic Assessment of Early-Stage Carbon Capture and Utilization Technologies—A Discussion of Current Challenges and Best Practices

The mitigation of climate change requires research, development, and deployment of new technologies that are not only economically viable but also environmentally benign. Systematic and continuous technology assessment from early technology maturity onwards allows assessment practitioners to identify economic and environmental characteristics. With this information, decision-makers can focus time and resources on the most promising technologies. A broad toolset for technology assessment exists—stretching from the well-established life cycle assessment (LCA) methodology to more loosely defined techno-economic analysis (TEA) methods and the increasingly popular principles of technology maturity assessment such as the concept of technology readiness levels (TRL). However, current technology assessment practice faces various challenges at early stages, resulting in a potential mismatch of study results and stakeholders' needs and an escalation of assessment effort. In this practice review, we outline current challenges in the interplay of LCA, TEA, and TRL and present best practices for assessing early-stage climate change mitigation technologies in the field of carbon capture and utilization (CCU). The findings help practitioners systematically identify the TRL of a technology and adapt technology assessment methodologies accordingly. We highlight the methodological challenges for practitioners when adapting the goal and scope, identifying benchmark technologies, creating a comprehensive inventory, comparing early stage to commercial stage, ensuring clarity of recommendations for decision-making under high uncertainty, and streamlining conventional LCA and TEA assessment approaches and provide actionable recommendations. Overall, this work contributes to identifying promising technologies faster and more systematically, accelerating the development of new technologies for climate change mitigation and beyond.

“…In addition, the concept of power-to-methane integrated with a chemical looping cycle was reported for simultaneous CCU . On the other hand, the techno-economic analysis of CO 2 conversion was conducted in a process scale using the standard parameters for CO 2 capture. − Recently, a techno-economic analysis and life cycle assessment were simultaneously performed for an integrated system using sorption-enhanced methanation …”

Carbon utilization in natural gas combined cycle (NGCC) power plants has attracted great attention due to necessary carbon reduction demands. In this study, NGCC power plants integrated with the carbon capture and utilization process (CCU) were developed: Case 2 (NGCC power plant with CO 2 conversion on precarbon capture) and case 3 (NGCC power plant with CO 2 conversion on postcarbon capture). Integrated process configurations were evaluated and compared with case 1 (NGCC power plant only with postcombustion carbon capture) in terms of technical (net power generation, natural gas consumption rate, syngas production rate, CO 2 quantity released into the environment) and economic (total capital cost, total annual revenue, return on investment, payback period, and cash flow) performance. Here, case 2 represented the most environmentally friendly option with the lowest CO 2 released. Besides, case 3 generated the highest amount of electricity due to a lower compression pressure demand for CO 2 utilization than storage in case 1. The economic analysis indicated that the payback periods of cases 1, 2, and 3 were 9.2, 17.18, and 6.9, respectively. Case 3 was the best option under the least capital expenditure, operating expenditure, and the highest annual revenue. Additionally, case 2 was competitive in terms of low total capital cost as compared to case 1. Therefore, the suggested NGCC power plant processes with CCU are viable options for reducing CO 2 emissions and improving the economics of NGCC power plants. In addition, the process may be used as a model for further CO 2 utilization from flue gas released by gas power plants.
