Only being powered by low-cost renewable energy, DAC can maximize its negative emission potential, in return, DAC can help the decarbonization of the power sector. Due to the intermittency of renewable energy, effectively integrating renewable energy with DAC currently remains a significant challenge. To address this research gap, this study focuses on exploring flexible operation strategies of the adsorbent based DAC system, coupling them with an actual photovoltaic (PV) power station, and making DAC systems participate in minute-level dispatch. The adsorbent based DAC system adopts a modular design, allowing each unit to operate as an independent load, not requiring continuous operation and enabling interruption between cycles or processes. Additionally, the adsorption process is curtailable and extendable to dynamically adjust the time of activating desorption. The flexible operational combination allows the DAC to better match the fluctuation of PV. Based on actual data and time-of-use pricing, this paper conducts a comparative techno-economic analysis of DAC and battery energy storage (BES) systems. The results indicate that deploying flexible DAC is the most cost-effective among different given scenarios. Deploying 46,800 DAC units primarily powered by solar curtailment can achieve the lowest cost of $30,000/MW-year for the selected 1000 MW PV power station, along with an 80 % curtailment consumption rate and annual 634,000 tons CO₂ captured. Before 2030, coupling DAC with PV can effectively address the curtailment issues and assist with peak shaving. As carbon prices gradually rise and adsorbent costs decrease, by 2040, DAC will release its negative emission potential, playing a crucial role in achieving net zero or even negative carbon emissions.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"14 ","pages":"Article 100304"},"PeriodicalIF":0.0,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142697771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that SMR plants fitted with high efficiency solvent-based capture technologies consume the same amount of natural gas as a conventional SMR plant without capture, despite capturing most of the CO₂ and producing the same amount of H₂. Overall, improvements in reboiler duty and reductions in capital costs can significantly reduce the cost of H₂ production and cost of capture. Particularly, the reboiler duty of pre-combustion capture and the capital cost of post-combustion capture have the greatest impact. Based on the results, research goals are suggested. Solvent development is recommended—particularly pre-combustion solvents—for reducing the reboiler duties, and process schemes to reduce the capital costs. Costlier but more efficient solvents can be considered. A sensitivity analysis using natural gas price shows that technological improvements can reduce the impacts of high natural gas prices.

This work presents a framework methodology to enhance the comparative analysis of decarbonization alternatives using site-specific techno-economic analysis, incorporating pertinent site-specific factors to obtain an enhanced indication of the optimal decarbonization solution. Site-specific cost factors such as energy supply options, space availability, site-layout constraints, local CO₂ interconnections, forced downtime, and premature decommissioning are considered. Qualitative site-specific factors and technology-specific attributes are assessed via expert elicitation with a retrofitability assessment matrix, generalizable to other process industries considering their site-level conditions. The framework methodology is demonstrated with a steam cracker plant case study, considering post-combustion CO₂ capture and pre-combustion CO₂ capture with hydrogen-firing in the cracker furnaces as decarbonization options. Results complemented with factor-specific sensitivity analysis highlight the extent of cost-escalation due to site-specific factors. The primary cost-contributing factor to retrofitability was the impact on production in existing sites, followed by the opportunity cost of utilizing valuable space on-site.

This study presents a framework for assessing representative CO₂ capture processes from key point sources through rigorous simulation. Eight scenarios were developed and compared, comprising four standalone processes (<em>i.e.</em>, physical absorption (PHYABS), chemical absorption (CHEABS), dual-reflux pressure swing adsorption (DRPSA) and pressure-temperature swing adsorption (PTSA)) and four hybrid processes that integrate different adsorption and absorption processes. To evaluate each scenario, an integrated indicator, the Economics, Equipment footprint, and Environmental Score (EEES), was introduced. Our results indicate that the standalone CHEABS exhibits the lowest EEES of 0.120, highlighting its technological readiness and superiority over other processes. In contrast, the standalone PHYABS (EEES=0.168) and the hybrid PHYABS/PTSA process (EEES=0.242) emerge as viable alternatives, balancing environmental performance with economic and spatial considerations. Standalone PTSA (EEES=0.465) and DRPSA (EEES=0.706) are less favorable because of their higher utility demands and larger equipment footprints. Similarly, hybrid processes, namely, DRPSA/CHEABS (EEES=0.891), CHEABS/PTSA (EEES=0.837), and DRPSA/PHYABS (EEES=0.784), are less advantageous across all three metrics. Furthermore, sensitivity analyses indicated that carbon permit prices exert a negligible effect on the process economics. Additionally, it appears that government subsidies may play a crucial role in facilitating the development of CO₂ capture technologies within the industrial sector.
