This is possible due to the interaction with carbonation and the formation of other iron containing phases. Here, the proposed calcium and chemical looping combustion using C₂F was examined using process modelling in ASPEN Plus and MTDATA. The low chemical potential of oxygen in C₂F allows CO/H₂ combustion to be endothermic in the lower temperature carbonator (particularly when reducing to Fe_xO), leading to a more exothermic reaction during oxidation in the higher temperature calciner. In this scheme, the heat of BFG combustion is chemically pumped from the lower temperature carbonator to the higher temperature calciner using the looping material, reducing the energy use in the calciner by around 40 kW/mol-BFG compared to the calcium looping alone or to the calcium copper looping. The reincorporation of CaO and Fe/Fe_xO into C₂F would allow the calcination temperature to be lowered to 770 °C (compared with calcium looping, which requires ∼ 900 °C), and the system can be entirely autothermal.</p></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"138 ","pages":"Article 104240"},"PeriodicalIF":4.6,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S175058362400183X/pdfft?md5=47b429d31805171a916ba07ee15cd6d7&pid=1-s2.0-S175058362400183X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142167855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the temperature of the injected fluid can also significantly impact the near-wellbore region through cooling-induced strain, stress changes, and fracturing, necessitating tailored monitoring strategies. This study evaluates the potential for near-well monitoring by examining the magnitude of strain and associated failure scenarios in reservoir formations down to approximately 2.6 km, where injected CO₂ may cause temperature decreases of around 80 °C. The combined effects of pore pressure and cooling on stress path and elastic-inelastic strain are assessed using laboratory triaxial test data and selected well logs. The impact of cooling was simulated directly via uniaxial strain tests or indirectly through multistage tests with Acoustic Emission (AE) monitoring. An analytical approach based on the Mohr-Coulomb failure criterion is employed to evaluate the stress path relative to the failure criteria. Results indicate that shallow, uncemented sands and weakly cemented sandstones predominantly exhibit elastic expansion in response to injection. In contrast, deep, stiff sandstones can experience cooling-induced contraction, inelastic damage, and even fracturing. The findings are further discussed in relation to well-based monitoring techniques, including fibre optics and other methods.</p></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"138 ","pages":"Article 104228"},"PeriodicalIF":4.6,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142157892","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}

Here, we consider the bowtie risk management framework to organize pre-screening efforts around a prospective CO₂ injection operation near Trüllikon, Switzerland. First, potential barriers/threats are appraised via a literature review of the regional seismotectonics, hydrogeology, and nearby induced seismicity cases – which suggests a natural propensity for earthquakes because of the proximity to the Neuhausen Fault and a lack of effective underlying hydrogeological barriers. Next, we engineer barriers to fault reactivation by quantifying the fault slip potential. The closest (∼700 m) and most susceptible (∼3.0 km) portions of the Neuhausen Fault would require ∼1.7 MPa and ∼0.47 MPa for reactivation, respectively. The most susceptible (unknown) faults are normal slip (168° strike) that require ∼0.23 MPa for reactivation. Injection simulations indicate pressure changes on Neuhausen Fault segments of 0.01–0.05 MPa – values that are 1–2 orders-of-magnitude smaller than those needed for fault reactivation. These engineered barriers limit the potential for fault reactivation. However, if these barriers prove totally ineffective, we have also designed a traffic light protocol as a reactive mitigation measure. Forecast estimates of nuisance, damage, and fatalities are used to infer the last-possible stopping-point based on a comparison with operation-ending risks encountered at Basel and St. Gallen. This indicates a red- and yellow-lights of M_W ∼2.0 and M_W ∼0.0, respectively. We synthesize these disparate pre-screening analyses to recommend performance targets for real-time seismic monitoring.

Therefore, this study aims to investigate the mechanisms and potential of anhydrite-CO₂-brine interactions for carbon storage. The experimental approach involved exposing anhydrite-rich rock to supercritical CO₂-brine environments under varying conditions of fluid composition. Mineral transformation of an outcrop anhydrite-rich rock sample in static reactor under subsurface conditions of elevated temperature (60 °C) and pressure (104 bar), in the absence and the presence of SrCl₂ was conduct for a one-month period. Mineralogical and geochemical analyses, including, solution analyses, X-ray fluorescence, X-ray diffraction, micro-computed tomography, and mechanical properties were conducted to examine the changes in the composition and rock structure resulting from the interactions. The experimental reactions revealed that anhydrite undergoes mineral transformation upon exposure to supercritical CO₂-saturated brine to form stable minerals including calcite, dolomite, magnesite, and strontianite, which contributes to the potential for long-term storage of CO₂ in the subsurface geologic media. The efficiency and extent of carbon mineralization were found to be influenced by brine composition.

Calcite was sourced from benthic microfossils, locally recrystallised to create a pore-filling cement. The mean pore throat and pore body diameter are about 17 nm putting the Rodby in the mesopore range and suggesting a predominance of slit-like pores.
