In this context, we present an advanced solar-driven photocatalyst, Pt-doped graphitic carbon nitride (Pt/g-C₃N₄), specifically engineered for enhanced photoreduction of CO₂. Our findings highlight the dual advantage of Pt/g-C₃N₄: enhanced visible light absorption and electron-hole pair dynamics, ensuring efficient carrier separation. Notably, the CO and CH₄ yields, when employing Pt/g-C₃N₄, surpassed those with the pristine g-C₃N₄ catalyst by factors of 3.1 and 4.3, respectively. Moreover, the Pt/g-C₃N₄ catalyst exhibited consistent high-efficiency of CO₂ conversion over successive cycles, emphasizing the catalyst's robustness.

The smaller size and lower cost of the PASS enables its permanent deployment in many locations to continuously monitor CO₂ storage reservoirs. To achieve continuous monitoring, distributed acoustic sensing (DAS) is also a vital technology. Based on DAS, we can continuously record the signal from the PASS in an extensive area, including within boreholes and offshore fields. Here we report application of the PASS for the borehole DAS system. We confirmed the PASS signal propagation to a depth of ∼1 km when we used a PASS with 630N at 50 Hz close to the wellhead and recorded the signal by the borehole fiber optic cable. The ability of the system to propagate the PASS signal to a depth of ∼1 km enables continuous monitoring of most CO₂ storage reservoirs with high temporal resolution.

To address the issue of the heterogeneity of rock formations in numerical simulations, it is common practice to homogenize rock layers with similar lithologies. However, the acceptability of the errors generated during homogenized computations is a major concern and should be investigated. Therefore, to study the influence of heterogeneity at the storage site on the CO₂ migration behavior, the Monte Carlo simulation–random finite element method (MCS-RFEM) was combined with a CO₂ two-phase flow model to compare the effects of the coefficient of variation (<i>C_v</i>) and correlation length (<i>λ_x</i>) of random reservoir permeability fields on the migration distance and extent of CO₂ storage under the same mean conditions. The results showed that higher <i>C_v</i> and <i>λ_x</i> values significantly reduced the CO₂ migration distance while increasing the spread extent. Compared to the homogeneous model, at a <i>λ_x</i> value of 100 m, the CO₂ migration distance decreased by 5.05%, while the profile sweep area increased by 6.20%. Concurrently, with increasing <i>C_v</i>, the area with a CO₂ volume fraction higher than 0.75 decreased by 20.22%, while an increase in <i>λ_x</i> resulted in a 42.35% increase in the area with a CO₂ volume fraction higher than 0.75. Therefore, reservoirs with high <i>C_v</i> and low <i>λ_x</i> values are more suitable for safely storing CO₂. © 2023 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"14 1","pages":"11-25"},"PeriodicalIF":2.2,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138515161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted supercritical CO₂ core flooding experiments using sandstone cores extracted from potential CO₂ reservoirs in the Ordos Basin, China. During the experiments, we reduced the water content of saturated cores by flushing with dry CO₂ and subsequently vacuumizing them at a temperature of 35°C to simulate sandstones with low water content. The experimental results demonstrate that the CO₂ permeability was initially high during the low differential pressure stage and remained constant as the differential pressure increased. In the carbonic acid solution injection experiment, we observed an increase in the flow rate of the solution with the continuous interaction in the cores from the Shanxi and Shihezi groups, while the Yanchang group exhibited the opposite effect. This increase in permeability can be attributed to mineral dissolution and the loss of fine particles. Conversely, the blockage of fine particles or the precipitation of dissolved minerals may lead to a decrease in permeability. After the CO₂–water–rock interaction, the CO₂ permeability decreased compared to before the interaction, indicating that adsorbed water, the precipitation of dissolved mineral, or pore throat blockage by fine particles could induce this permeability decrease. The impact of adsorbed water on the decrease in CO₂ permeability is significant. Additionally, the CO₂–water–rock interaction caused corrosion on the anorthite surface. Furthermore, calcite dispersed in connected pores displayed a more pronounced dissolution compared to cemented calcite. © 2023 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"14 1","pages":"197-208"},"PeriodicalIF":2.2,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138519854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In CCS, captured CO₂ is sequestered in saline aquifers within sedimentary basins. The CO₂ storage capacity and the rate of injection are functions of the geology of the saline aquifer, which is uncertain. To minimize impacts of this uncertainty, CCS projects could include backup plans, such as co-locating geologic CO₂ storage (GCS) sites with or near existing CO₂-enhanced oil recovery (CO₂-EOR) operations. These “stacked storage” projects could hedge against uncertainty in the saline formation performance because captured CO₂ could be injected into either location in the event of unexpected events (e.g., the injectivity decreases). Here, we investigate the possibility and ramifications of developing CCS networks in Oklahoma that are amendable to stacked storage. We find that stacked storage is possible in Oklahoma but the counties with the lowest-cost saline storage resources do not have existing CO₂-EOR operations. At the systems level, we find it is slightly more expensive (e.g., $1/tCO₂ to $5/tCO₂) to site GCS in counties with CO₂-EOR projects. This increased expense is largely due to increased CO₂ transportation costs because hundreds of km of additional pipeline is required to capture CO₂ from the lowest-cost sources. Overall, our results suggest that it is optimal to build more pipelines and avoid injecting CO₂ in some of the lowest-cost saline storage resources, to enable capturing CO₂ from the least-cost sources. © 2023 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":"13 6","pages":"763-779"},"PeriodicalIF":2.2,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ghg.2244","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135240758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As it is difficult to secure combustion stability in a low-temperature atmosphere, the experiment was conducted in a sufficiently-warmed atmosphere (90 ± 2.5 °C), and the combustion, emission, and efficiency results under each operating condition were experimentally compared. At 1500 rpm, the addition of 10% hydrogen resulted in a notable 20.26% surge in the maximum torque, reaching 263.5 Nm, in contrast with the case where only ammonia fuel was used.

Shale are source rocks, and thus, there is a continuous induced diagenetic process that can alter their properties as they reaches maturity at greater in situ temperature. However, there are significant knowledge gaps in the possibility of CO&lt;sub&gt;2&lt;/sub&gt; utilization during this diagenetic process (thermal maturation) to achieve long-term CO&lt;sub&gt;2&lt;/sub&gt; storage.

This is followed by inducing the unexposed and CO&lt;sub&gt;2&lt;/sub&gt;-exposed shales to thermal maturity. Subsequently, we evaluated the total organic carbon (TOC), liberated hydrocarbons (&lt;i&gt;S&lt;/i&gt;&lt;sub&gt;2&lt;/sub&gt;), and the mineralogical and mechanical properties of the mature and CO&lt;sub&gt;2&lt;/sub&gt;-exposed mature shales.

The results indicate that if CO&lt;sub&gt;2&lt;/sub&gt; is injected into shales before attaining maturity, higher hydrocarbon production and more significant mechanical weakness can be expected when they attain maturity in Bakken shales (+30% liberated hydrocarbons; −31% Young's modulus; −34% hardness) and Green Rivers shales (+8% liberated hydrocarbons; −40% Young's modulus; −30% hardness), and this is relative to Bakken and Green River shales without CO&lt;sub&gt;2&lt;/sub&gt; injection before attaining thermal maturity.
