Although many discussions and practical procedures have been developed, large-scale CO₂ storage in carbonates has not been implemented due to practical risks associated with rapid geochemical interactions. This study attempts to evaluate the feasibility of CO₂ storage in carbonate chalk formations by focusing on changes in storage capacity (porosity) and injectivity (permeability) over time. A series of laboratory tests were carried out on Stevns Klint chalk from Denmark after exposure to CO₂ for 37 days at a fluid pressure of 15 MPa and a temperature of 50 °C. The results obtained indicated a large removal of Ca⁺² ions from CO₂ saturated water solution and strong precipitation of secondary calcite in the pore structure, which reduced the porosity and permeability of the samples. It seems that CO₂ injection into chalk should be done very carefully, as the progressive dissolution of calcite and saturation of the formation water will initiate large secondary calcite precipitation in the long term, leading to a reduction in injectivity and storage capacity over time.</p></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"123 ","pages":"Article 103832"},"PeriodicalIF":3.9,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1618201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An initial dataset was generated by changing eight design variables, and machine-learning models were built using random forest classifier and Gaussian process regression. Pareto solutions were predicted using a genetic algorithm (NSGA-II) with the constraints of purity, recovery, and temperature, and were verified via process simulation. Verified data were added to the dataset, and model building, prediction, and verification were repeated. Eventually, 56 Pareto solutions were obtained after 11 iterations. In the final Pareto solutions, CO₂ emissions increased from 0.56 to 0.6 t-CO₂/t-CO₂ with a decrease in cost from 74 to 66 USD/t-CO₂. The trends and composition of each objective variable were examined, and the optimal structure of the equipment and operation conditions was clarified.

A solution to increase both power production and utilization efficiency of these systems is hybridization with a biomass fuel source. In this work, we introduce and verify the concept of biomass hybridization combined with in-line dissolution and reinjection of biomass flue CO₂. This subclass of bioenergy and carbon capture and storage (BECCS), termed geothermal-BECCS, has improved power production and negative CO₂ emissions.

Our analysis shows that by adopting advanced coal technologies and carbon dioxide capture and sequestration (CCS) options, up to 45% CO₂ emission reduction can be achieved over business-as-usual scenario (BAU) by 2050. This is possible even when coal use would increase to nearly 2200 Mt in 2050 as against 870 Mt in 2017-18. Without CCS, coal use could peak at 1200 Mt with 22% CO₂ reduction over BAU in 2050 but in that case nuclear and renewable energy would become pivotal in meeting energy demand. The paper concludes that a win-win integration of energy security and deep GHG emission mitigation is possible through a large-scale integration of advanced coal technologies and CCS in Indian energy systems.

Both approaches have worked, but they may struggle in places like the Gulf of Mexico where complex geologic structure can invalidate simple assumptions of radial plume spread and buoyant traps are commonly unattractive due to numerous legacy well penetrations. We propose identifying prospective storage sites by fetch area (drainage cell) rather than by buoyant closure alone. Doing so offers 1) greater freedom in siting injectors to avoid surface and subsurface constraints, including legacy wells that tend to cluster on structural high; and 2) a coherent flow regime in which buoyancy drives all injected CO₂ toward a common high. This strategy gives space to dissipate injection pressure and minimize the number of legacy wells needing review. It may also offer 1) better injectivity by bringing synclines and associated channel axes into play; and 2) potentially improved capacity by tapping a larger rock volume and taking advantage of migration losses.</p></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"122 ","pages":"Article 103817"},"PeriodicalIF":3.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1627019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
