CaL process has several advantages over conventional systems such as availability of abundant and low cost CaO sorbents, reduced environmental impact, lower greenhouse emissions and energy requirements. CaL offers easy and innovative schemes to integrate renewable energy such as concentrated solar power, oxy-fuel and chemical looping process and steam dilution to further enhance the overall efficiency of the system. The review first focuses on summarizing the characteristics and operational parameters of these process integrated CaL facilities while highlighting key experimental findings. The examination of innovative sorbent materials utilized within integrated CaL processes has been addressed, emphasizing pathways directed towards enhancing reaction efficacy, energy conservation, and holistic sustainability attained via process integration and intensification. Meanwhile, strategies to overcome the limitation of CaL process in terms of rapid sintering of sorbent particles over time have also been discussed. Further, the approaches for integrating CaL into industrial plants such as power, cement and steel plants have been identified and compared to realize significant reduction of energy penalty compared to conventional system. The impact of multivariate latent variable (LV) modeling on the integrated CaL process has been examined. Based on the review, CaL showed equivalent or better performance in reducing CO₂ emissions (global warming potential or climate change impact indicator) in comparison to alternative scenarios.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"14 ","pages":"Article 100371"},"PeriodicalIF":0.0,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143157582","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}

However, there is a lack of understanding of the potential and costs of CCS technology in the WtE industry, particularly from the perspective of facility. Given with this situation, a facility-level integrated assessment model including CCS source-sink matching optimization model and tech-economic assessment model was developed in this study to reveal the application potential and costs of CCS technology in China's WtE industry, and to quantify the impacts of different incentive policies on CCS technology deployment. The results showed that matching WtE facilities with nearby carbon sinks enables significant CO₂ reductions, ranging from 0.3 Gt annually to a cumulative 6.9 Gt over the facilities’ operational lifetimes. The emission reduction costs for all WtE facilities range from -612.9 to 506.5 CNY/t CO₂, with an average profit of 412.5 CNY/t CO₂ when considering enhanced oil recovery (EOR). However, saline aquifer storage demands robust policy incentives due to limited direct economic benefits. Facilities with larger capacities and longer remaining lifespans are most cost-effective for CCS retrofitting. Spatial analysis underscores geographical disparities in CCS potential, with eastern coastal regions displaying greater feasibility due to higher WtE density and proximity to carbon sinks. Among incentive measures, waste disposal fee subsidies and feed-in tariffs exhibit varying efficiency, while carbon market mechanisms show potential for long-term sustainability. To promote the application of CCS technology and exert its emission reduction effect, a collaborative strategy combining market-driven carbon pricing and government subsidies should be adopted in the future, and priority should be given to the retrofitting of high-capacity and long-life facilities.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"14 ","pages":"Article 100364"},"PeriodicalIF":0.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143157442","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}

This study proposes a novel process integrating calcium looping and dry reforming of methane (CaL-DRM) based on an “in-situ carbon capture and conversion” strategy to enhance the energy efficiency and decarbonization in the cement production process. Models for both conventional cement production process model and the CaL-DRM processes were developed using Aspen Plus to compare the mass flow and process energy balances of conventional cement production with the CaL-DRM process. The modelling results were validated by the cement plant operating data and published results. Sensitivity analyses were performed to optimize key production parameters, including CH₄/O₂ = 1.37 and CaCO₃/CH₄ = 0.5, which resulted in the highest conversion efficiencies of CO₂ and CH₄. Subsequently, the optimization of the tertiary air volume and the proportion of hot raw meal entering the carbonator was carried out. The optimal tertiary air volume was found to be less than 28529 Nm³/h, and 13% of the hot raw meal was directed to the carbonator. With these conditions, the process thermal efficiency can be increased from 58 % to 86 %. CO₂ emissions were analyzed at key stages of cement production process, focusing on fuel combustion and carbonate decomposition at the calciner and rotary kiln, with a comparison of the conventional method and the CaL-DRM process to quantify emissions at each stage. The results indicate that 852.3 kg CO₂ per ton of cement clinker can be converted to produce 1680 kg of syngas per ton of cement clinker along with cement clinker. Additionally, up to 62.5 kg CO₂ per ton of cement clinker can be captured by the carbonator, reducing the CO₂ volume fraction in flue gas from 23.29 % to 0.24 %, thus eliminating the need for subsequent CO₂ purification and transport.
