In TIAM-FR, a bottom-up optimization model of the global energy system, we developed an explicit model of the global cement industry to analyze the potential contribution of BECCS to producing cleaner cement. We investigated the technical and policy conditions favorable to BECCS deployment and sustainability, considering different future biomass potentials, yields, rotation periods, and management costs. Our findings demonstrate that BECCS can significantly contribute to cement decarbonization, making it easier, quicker, and more cost-effective to achieve. However, the current bioenergy use and policy landscape falls short of meeting the 2050 target. Scaling bioenergy use from 3% of the global energy mix to more than 40%, along with strengthening global climate policies, is essential. By leveraging the potential of bioenergy substitution up to 80% and extensively invest in CCS processes, carbon neutrality in cement production could be advanced by 10 to 18 years, enabling the production of net-negative cement.

In this study, we introduced and validated a batch dissolution experimental protocol for efficient quantification of labile Mg, an indicator of carbon mineralization reactivity derived from ultramafic rocks, minerals, and tailings. This method is used to characterize labile Mg content in various ultramafic minerals, including serpentine and hydrotalcite group minerals, as well as rocks like serpentinite, dunite, harzburgite, and tailings. Antigorite exhibits the lowest labile Mg content within the serpentine mineral group, whereas chrysotile releases the most. Differences in labile Mg content within the hydrotalcite group depend on the trivalent cation species, with Fe³⁺-rich pyroaurite and iowaite demonstrating higher labile Mg content than Cr³⁺, Al³⁺-rich stichtite and hydrotalcite. We found that grain size impacts the reactive surface area of ultramafic rocks and tailings, while protolith composition and rock alteration stages affect mineralogy. Consequently, under consistent geochemical conditions, we identified mineral type, abundance and reactive surface area as primary controls of labile Mg content. Principal Component Analysis (PCA) further validated our findings, showing that mineralogy and reactive surface area could account for over 90 % of the variability in labile Mg measurements.

However, the storage resources of a reservoir are heavily linked to the associated wells injectivity, mainly in the near wellbore region. The formation of CO&lt;sub&gt;2&lt;/sub&gt; hydrates due to CO&lt;sub&gt;2&lt;/sub&gt; injection, and the associated thermodynamic phenomena, may greatly alter the petrophysical properties of these injection zones. The adiabatic depletion leads to a large temperature decrease which, associated with local “cold” conditions, can bring the system into the CO&lt;sub&gt;2&lt;/sub&gt; hydrates stability zone in the near wellbore area. If those conditions are encountered, a severe reduction, or even loss, of injectivity can be anticipated. CO&lt;sub&gt;2&lt;/sub&gt; hydrate can plug partially, or totally, the pore bodies and/or pore throats.

In static conditions, after setting the system to a targeted water saturation (ranging between 10 and 50 %), experiments were conducted in an in-house high-pressure NMR set-up. Taking advantage of the huge relaxation contrast between protons, part of water molecules and hydrates, the average water content can be measured continuously during hydrate formation and dissociation as well as water profiles along the sample. The capability of the Peltier cooled NMR system to accurately control the temperature, allows a good determination of the thermodynamic stability limits. The influence of the water saturation is presented and discussed.&lt;/div&gt;&lt;div&gt;The effect of hydrate formation on the permeability of porous rock is also studied.

One challenge in assessing the feasibility of CCS in chalk is the contradictory experimental results reported in literature and indicating both a softening and strengthening of rocks in contact with supercritical CO₂. To account for this uncertainty, coupled hydro-mechanical-chemical simulations are conducted and the storage capacity and deformation behavior of the depleted Harald East field are assessed under three different scenarios. The supercritical CO₂ is assumed to have no effect on chalk's mechanical properties (scenario 1) as well as a strengthening (scenario 2) and softening effect (scenario 3). The results indicate that the ultimate storage capacity is primarily controlled by chalk compaction occurring during hydrocarbon production with a negligible impact of porosity reduction caused by CO₂ injection. Besides, assuming a strengthening or softening effect of CO₂ on rock strength has a minor impact on overall reservoir and overburden deformation. Only 4 % discrepancy is predicted in reservoir and seafloor subsidence between scenarios 2 and 3. Finally, irreversible deformation during CO₂ injection is spatially restricted around the injectors due to the difference in propagation velocities between the CO₂ and pressure fronts.

Shale rocks play a role in both trapping CO₂ and preventing its escape, thus ensuring containment security. However, shale integrity can be compromised upon interaction with CO₂, which should be carefully evaluated. This study explores the dynamic behaviour of CO₂-shale interaction at the pore scale, focusing on the physiochemical interactions between CO₂ and shale, including the impact of shale swelling, where CO₂ adsorption causes matrix deformation and alters fracture sizes. Here, we utilise image-based analyses to develop a triple-porosity pore network model (PNM), reflecting the complex nano- to micro-scale structure of shale, to examine CO₂ injection into methane-saturated environments. The study particularly focuses on the impact of matrix deformation caused by gas sorption (swelling), competing with mechanical stress effects. Findings indicate that CO₂ injection leads to a reduction in fracture permeability by up to 17 % and 10 % in low- and high-density fractured shales, respectively, under high confining pressure (50 MPa), and by 15.5 % and 8 % under lower confining pressure (25 MPa). Although fracture permeability versus CO₂ injection pressure reduces monotonically at the lower confining pressure, that of the higher confining pressure is non-monotonic, where the fracture permeability shows an increase due to effective stress change. Additionally, the average fracture aperture size decreases by 50 nm in low-density and 25 nm in high-density fractured shales, highlighting the critical balance between swelling effects and mechanical stresses in the geological sequestration of CO₂.</div></div>","PeriodicalId":334,"journal":{"name":"International Journal of Greenhouse Gas Control","volume":"141 ","pages":"Article 104294"},"PeriodicalIF":4.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143095682","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}
