The benefits of cloud storage come along with challenges and open issues about availability of services, vendor lock-in and data security, etc. One solution to mitigate the problems is the multi-cloud storage, where the selection of service providers is a key point. In this paper, an algorithm that can select optimal provider subset for data placement among a set of providers in multicloud storage architecture based on IDA is proposed, designed to achieve good tradeoff among storage cost, algorithm cost, vendor lock-in, transmission performance and data availability. Experiments demonstrate that it is efficient and accurate to find optimal solutions in reasonable amount of time, using parameters taken from real cloud providers. 展开更多

Developing efficient catalysts is pivotal for advancing MgH2-based hydrogen storage systems.In this study,a novel catalyst,graphene oxide-supported oxygen vacancy-rich Co3O4and Ni nanoparticles(Ni-OV-C@GO),was synthesized to enhance the hydrogen storage performance of MgH2.The catalyst dramatically improved the kinetics of MgH2,lowering the initial hydrogen desorption temperature of Ni-OV-C@GO-MgH2-7 to 438 K,which is 386 K lower than that of as-milled MgH2.The composite achieved 5.0 wt%hydrogen absorption at 423 K within 600 s and retained 97.3%capacity after 30 cycles.Notably,the activation energy for H2desorption was reduced to 40.78 kJ/mol,an 80%decrease compared to pristine MgH2.The in-situ formation of CoMg2/CoMg2H5and Mg2Ni/Mg2NiH4acted as“hydrogen pumps”,facilitating multiple hydrogen transfer pathways.Additionally,oxygen vacancies elongated Mg-H bonds,enhancing dehydrogenation kinetics through catalytic effects.These findings provide valuable insights into improving hydrogen adsorption and desorption kinetics in MgH2-based systems. 展开更多

The construction of underground gas storage(UGS)in a large-scale low-permeability lithologic gas reservoir presents an immense engineering challenge.Under the context of UGS,research on structural characteristics and storage capacity at the microscopic scale is insufficient,making it difficult to provide effective support for the engineering scheme.In this study,the microscopic storage spaces of a typical lithologic gas reservoir(i.e.,YL block in the Ordos Basin)are comprehensively analyzed through experimental techniques(represented by computed tomography scanning),digital core analysis,and fractal analysis.Furthermore,the feasibility of UGS construction is examined.The results demonstrate that the large-scale low-permeability lithologic gas reservoir exhibits significant zonal heterogeneity in its microscopic structural characteristics at both morphological and statistical levels.Specifically,the microscopic storage spaces of the core zone within the YL block are notably higher than those in the transition and periphery zones,characterized by larger aperture,less tortuous,higher aggregation and connectivity.Consequently,the core zone provides adequate storage capacity and injection-extraction capability for large-scale underground storage of natural gas.In contrast,the transition and periphery zones exhibit inferior microstructural,storage,and flow properties,which are not suitable for rapid injection and production.However,these zones show a fairly strong lateral sealing capability,which can be utilized as a monitoring area to evaluate UGS integrity.These findings indicate that the reservoir's microstructural features meet the essential requirements of storage capacity,injection-extraction capability,and lateral sealing property for UGS construction.Based on this understanding,a series of zone-differentiated UGS engineering suggestions are proposed,including zonal function specification,well type selection,well deployment scheme,and management of old wells.These findings can provide valuable insights for the assessment and implementation of UGS projects from such gas reservoirs. 展开更多

To address the challenge of balancing thermal management and thermal runaway mitigation,it is crucial to explore effective methods for enhancing the safety of lithium-ion battery systems.Herein,an innovative hydrated salt composite phase change material(HSCPCM)with dual phase transition temperature zones has been proposed.This HSCPCM,denoted as SDMA10,combines hydrophilic modified expanded graphite,an acrylic emulsion coating,and eutectic hydrated salts to achieve leakage prevention,enhanced thermal stability,cycling stability,and superior phase change behavior.Battery modules incorporating SDMA10 demonstrate significant thermal control capabilities.Specifically,the cylindrical battery modules with SDMA10 can maintain maximum operating temperatures below 55°C at 4 C discharge rate,while prismatic battery modules can keep maximum operating temperatures below 65°C at 2 C discharge rate.In extreme battery overheating conditions simulated using heating plates,SDMA10 effectively suppresses thermal propagation.Even when the central heating plate reaches 300°C,the maximum temperature at the module edge heating plates remains below 85°C.Further,compared to organic composite phase change materials(CPCMs),the battery module with SDMA10 can further reduce the peak thermal runaway temperature by 93°C and delay the thermal runaway trigger time by 689 s,thereby significantly decreasing heat diffusion.Therefore,the designed HSCPCM integrates excellent latent heat storage and thermochemical storage capabilities,providing high thermal energy storage density within the thermal management and thermal runaway threshold temperature range.This research will offer a promising pathway for improving the thermal safety performance of battery packs in electric vehicles and other energy storage systems. 展开更多

LiAlH4is hindered for practical hydrogen storage by its high decomposition temperatures,slow kinetics,and poor reversibility.To address the kinetic issues,this study introduces a tubular g-C3N4-supported NiFe-layered double hydroxide(g-C3N4@Ni Fe-LDH)nanocomposite as a catalytic dopant for LiAlH4.The composite,synthesized via solvothermal and pyrolysis methods,features a welldefined tubular morphology(~3μm in length,~200 nm in diameter),which facilitates its homogeneous dispersion and intimate interfacial contact with LiAlH4during ball milling.Doping with 7wt%of this catalyst dramatically enhances the dehydrogenation kinetics of LiAlH4.The onset dehydrogenation temperature is lowered to 79.2℃,and 6.8wt% of hydrogen is released in two steps.Kissinger analysis reveals that the apparent activation energies for these steps are reduced by 43.0% and 54.8%,respectively,demonstrating significantly improved dehydrogenation kinetics.Mechanistic studies suggest that the synergistic effect between the g-C3N4support and NiFe-LDH,along with the potential in-situ formation of active interfacial species during dehydrogenation,contributes to this improvement. 展开更多

We employed a one-step hydrothermal method to in situ grow spherical NiS2nanoparticles on the surface of MXene,successfully constructing a NiS2-MXene hybrid composite.This study demonstrates that the integration of a NiS2-MXene hybrid composite into MgH2substantially improves its hydrogen storage performance.Specifically,the composite reduces the initial dehydrogenation temperature of MgH2by 118℃,lowering it from 310℃(pure MgH2)to 192℃.At 300℃,it can release 5.87wt% of hydrogen within 12 min.Furthermore,it demonstrates the ability to absorb hydrogen under ambient temperature conditions,with approximately 2.96wt% of hydrogen being absorbed as the temperature increases from room temperature to 50℃.The activation energies for hydrogenation and dehydrogenation of the NiS2-MXene-MgH2composite reduced by 33.7 and 40.6 kJ·mol-1,respectively,in comparison to those of pure MgH2.Mechanistic studies demonstrate that NiS2-MXene enhances hydrogen storage performance through multiple synergistic effects.Specifically,the multivalent titanium in MXene establishes efficient electron transport pathways,promoting hydrogen binding and dissociation.Moreover,the in situ formation of Mg2Ni/Mg2NiH4and MgS creates numerous phase interfaces,offering abundant active sites that facilitate both the dissociation and recombination of hydrogen molecules.Furthermore,the high specific surface area of MXene effectively inhibits agglomeration between the catalyst and Mg/MgH2,thereby maintaining structural stability and reactivity. 展开更多

The use of industrial-grade FeV80 master alloy in the synthesis of solid hydrogen storage alloys,rather than pure V,offers substantial economic advantages.However,FeV80 master alloy contains about 5 wt%of Al,Si,O and other impurities,which adversely affect the hydrogen storage performance.In this work,the effective dehydrogenation capacity of Ti31Cr35(FeV80-Ce)34 alloy prepared by Ce pre-refining FeV80master alloy process reaches 2.42 wt%.By comparing the phase distribution and composition before and after pre-refining,Ce pre-refining significantly reduces the presence of Al and O,inhibits the formation of Ti-rich phase and the generation of SiO2 in Ti31Cr35(FeV80-Ce)34 alloys.By X-ray photoelectron spectroscopy(XPS)analysis,the metal content of the matrix element increases and the binding energy decreases after Ce pre-refining.The slope factor of pressure-composition-temperature(PCT)curve decreases from 0.60 to 0.48 after Ce pre-refining,which improves the dehydrogenation perfo rmance.The dehydrogenation activation energy and enthalpy change of the Ti31Cr35(FeV80-Ce)34 alloy before and after pre-refining are also calculated using kinetics and PCT curves.Furthermore,the Ti31Cr35(FeV80-Ce)34 alloy exhibits a capacity retention of 81%after 200 cycles,surpassing reported values for FeV80-based hydrogen storage alloys.It provides a new idea for developing low-cost and high-capacity FeV80-base hydrogen storage alloys. 展开更多

AB2-type Ti-based hydrogen storage alloys(HSAs)are promising for industrial hydrogen feeding systems due to their moderate operating conditions and high hydrogen storage capacity.However,their practical application is hindered by unavoidable impurity gases in hydrogen feedstocks,which significantly impair the performance of HSAs.Furthermore,the absence of clear evaluation criteria for poisoning behaviors and mechanisms hinders efforts to develop effective mitigation strategies.To address this gap,we used calculated surface interaction energy changes(ΔE)and experimental investigations to classify and rank the poisoning potential of impurity gases on a C14 Laves-phase Ti0.86Zr0.15Mn1.5Cr0.07(VFe)0.43 alloy.Impurity gases were classified into two types of weak-adsorption and strong-adsorption impurity gases by comparing theirΔE with that of H2(ΔE_(H2)=-1.6001 eV).AsΔE>ΔE_(H2) ,weak-adsorption impurity gases(Ar,He,CH4,and N2)induce poisoning by forming enriched blocking layers that impede H2 diffusion.This blocking effect can be alleviated under gas flow conditions.AsΔE<ΔE_(H2),strong adsorption gases are further divided into two types based on their reactivity with the alloy.Non-reactive strong-adsorption impurity gases(CO and CO2 )preferentially occupy surface active sites,blocking H2 adsorption and dissociation.In contrast,reactive strong-adsorption impurity gases(such as O2)form dense passivation layers that completely prevent hydrogen ingress.Accordingly,surface modification offers an effective approach to mitigate gas-induced poisoning by altering the interaction mechanism.This study establishes the parameter-based criteria for classifying impurity gas poisoning mechanisms in AB2-type Ti-based HSAs.It provides fundamental insights for guiding the design of poisoning-resistant materials and the development of mitigation strategies. 展开更多

The sealing capacity of caprock is critical for preventing CO2migration and ensuring the safety of geological storage.However,existing research lacks a comprehensive overview of its sealing mechanisms and failure risks.Here,recent findings on caprock sealing mechanisms,its influencing factors,failure risks,and evaluation methods are summarized.The main results include the following:(i)Caprock sealing mechanisms include capillary,hydraulic,hydrocarbon concentration,and hydrate sealing.(ii)Capillary and hydrate sealing block fluid-phase CO2,hydrocarbon concentration sealing prevents diffusive CO2,and hydraulic sealing prevents fluid and water-soluble phases.(iii)The sealing capacity is influenced by the storage site,stratigraphic environment,and caprock properties,with breakthrough pressure ranked as follows:gypsum rock>salt rock>mudstone/shale>limestone>silty mudstone.(iv)Diffusion leakage occurs when the diffusion coefficients is less than 10-12m2/s,the seepage leakage ranges between 10-8m2/s and 10-12m2/s,and the fracture leakage is greater than 10-8m2/s.(v)Hydro-mechanical(HM)coupling mechanisms,including CO2diffusion,breakthrough migration,uplift deformation,and fracture flow,are essential for leakage risk simulations.Future research should address sealing mechanisms under complex conditions,define leakage risk thresholds,optimize multiphysical coupling computations,and implement effective engineering solutions to mitigate leakage risk. 展开更多

In order to address environmental pollution and resource depletion caused by traditional power generation,this paper proposes an adaptive iterative dynamic-balance optimization algorithm that integrates the Improved Dung Beetle Optimizer(IDBO)with VariationalMode Decomposition(VMD).The IDBO-VMD method is designed to enhance the accuracy and efficiency of wind-speed time-series decomposition and to effectively smooth photovoltaic power fluctuations.This study innovatively improves the traditional variational mode decomposition(VMD)algorithm,and significantly improves the accuracy and adaptive ability of signal decomposition by IDBO selfoptimization of key parameters K and a.On this basis,Fourier transform technology is used to define the boundary point between high frequency and low frequency signals,and a targeted energy distribution strategy is proposed:high frequency fluctuations are allocated to supercapacitors to quickly respond to transient power fluctuations;Lowfrequency components are distributed to lead-carbon batteries,optimizing long-term energy storage and scheduling efficiency.This strategy effectively improves the response speed and stability of the energy storage system.The experimental results demonstrate that the IDBO-VMD algorithm markedly outperforms traditional methods in both decomposition accuracy and computational efficiency.Specifically,it effectively reduces the charge–discharge frequency of the battery,prolongs battery life,and optimizes the operating ranges of the state-of-charge(SOC)for both leadcarbon batteries and supercapacitors.In addition,the energy management strategy based on the algorithm not only improves the overall energy utilization efficiency of the system,but also shows excellent performance in the dynamic management and intelligent scheduling of renewable energy generation. 展开更多

Shared energy storage helps lower user investment costs and enhances energy efficiency,which is considered a pivotal driver in accelerating the green transition of energy sectors.In view of the increasing demand for hydrogen,this paper proposes a bi-level optimization of configurations and scheduling for combined cooling,heating,and power(CCHP)microgrid systems considering shared hybrid electric-hydrogen energy storage service.The upper-level model addresses the capacity allocation problem of energy storage stations,while the lower-level model optimizes the operational strategies for the multi-microgrid system(MMS).To resolve the complexity of the coupled bi-level problem,Karush-Kuhn-Tucker(KKT)conditions and the Big-M method are applied to reformulate it into a solvable mixed-integer linear programming(MILP)model,compatible with CPLEX.The economic viability and rationality of the proposed approach are verified through comparisons of three cases.Numerical results show that the proposed approach reduces user annual costs by 20.15%compared to MMS without additional energy storage equipment and achieves 100%renewable absorption.For operators,it yields 5.71 M CNY annual profit with 3.02-year payback.Compared to MMS with electricity sharing,it further cuts user costs by 3.84%,boosts operator profit by 60.71%,and shortens payback by 15.88%. 展开更多

The strain energy storage index(WET)is a crucial index for evaluating rockburst proneness.Interestingly,when conducting tests to obtain WET,variations exist in the shape of coal or rock specimens.However,whether shape factors affect WET has not been theoretically and experimentally verified.In this study,to investigate the independence of WET from specimen shape effects,its rationality was first theoretically derived based on the linear energy storage(LES)laws of rock,indicating that WET is influenced by the energy storage coefficient(ESC)of the rock.Two typical rock materials(granite and red sandstone)with different rockburst proneness were selected to verify the migration effect of cubic and cylindrical specimens on WET via uniaxial compression tests.The experimental results revealed that the mechanical behavior characteristics of rocks were affected by the shape of cylindrical and cubic specimens,whereas the WET and ESC were opposite.Furthermore,the practical WET values closely approximate the theoretical values of energy storage-dissipated ratio predicted by the LES law,converging to the peak-strength strain energy storage index(WPET).Based on the LES law,the influence of specimen shape on WET and WPET was further discussed,concluding that WET and WPET are independent of specimen shape effects.Furthermore,the WPET is more stable than WET and reflects the relative magnitude of energy storage and dissipation during the entire pre-peak of rock.Thus,the peak-strength strain energy storage index can be used as a substitute for WET in evaluating the rockburst proneness of rock. 展开更多

Groundwater overexploitation in northern Henan Province has led to significant land subsidence and aquifer degradation.This methodologically driven study proposes a physically consistent framework that integrates Sentinel-1 A-based Multi-Temporal Interferometric Synthetic Apertu re Radar(MT-InSAR)data(2017-2022)with long-term groundwater head observations to invert elastic and inelastic skeletal storage coefficients and assess total groundwater storage(TGWS)changes.The framework is applied to the Anyang-Puyang Plain as a representative case study.MT-InSAR deformation time series were combined with Multi-channel Singular Spectru m Analysis(MSSA)decomposition and polynomial fitting to extract seasonal and long-term trends,enabling spatially distributed inversion of aquifer parameters.Results show strong spatial coupling between land subsidence and hydraulic head decline(maximum Pearson r is 0.993),with deformation dominated by inelastic compaction.The elastic storativity ranges from 0.00093 to 0.01596,whereas the inelastic storativity,ranging from 0.0362 to 0.0457 indicates irreversible compaction processes associated with a cumulative groundwater loss of approximately3.01×108 m3.Based on the long-term groundwater level observations collected in this study and the inferred assumption of preconsolidation head,the TGWS loss reached-12.27×109 m3,with a mean annual rate of-2.19×109 m3/yr and pronounced depletion in northern areas.Standard deviational ellipse(SDE)analysis revealed a north-westward shift of the depletion centre and enhanced spatial clustering.These findings provide critical hydromechanical insights and quantitative constraints for future groundwater regulation and aquifer recovery strategies in overdrawn regions. 展开更多

The irrigation districts of northern China face issues such as water scarcity,inability to effectively utilize flood resources,and groundwater overexploitation.In view of these challenges,this study proposes a new concept of deep storage irrigation through flood resources utilization.However,whether deep storage irrigation can recharge deep soil moisture and sustain crop production still requires further study.A two-year field experiment was conducted on summer maize in the Guanzhong Plain with five soil wetting layer depths(T1:60 cm;T2:90 cm;T3:120 cm;T4:150 cm;T5:180 cm)and soil saturation moisture content as the irrigation upper limit.The results presented that the ranges of deep soil moisture recharge in the100–200 cm soil profile(SMS100–200)was 73.34–267.42 and 0–150.03 mm in 2021(wet season)and 2022(normal season).When the effective precipitation and irrigation exceeded 390 mm,the SMS100–200began to linearly increase.The highest grain yield(GY)were observed at T2 and T3 treatments in 2021(11.44 t ha-1)and 2022(11.25 t ha-1),respectively.The maize GY of T4 in 2021 and T5 in 2022 were only 3.9 and 5.7%lower than the maximize GY,respectively.However,the SMS100–200for T4 and T5 were 2.4 and 5.0 times that of T2 and T3 treatments in 2021 and 2022,respectively.Overall,the further increase in irrigation amounts induced only a slight decrease in grain yield,but it significantly increased deep soil moisture recharge.Therefore,the deep storage irrigation breaks through the traditional idea of water-saving irrigation with limited water resources,which can be utilized as an effective alternative to address the issues of water scarcity,low flood resources utilization,and groundwater level declines in the irrigation districts of northern China. 展开更多

The energy transition increasingly requires holistic approaches that integrate electricity,heating and cooling,water management,industrial processes,transport,and environmental considerations within coherent system frameworks.Such integration is essential for achieving deep decarbonisation while maintaining reliability,affordability,and resource efficiency across diverse regional and sectoral contexts.This Special Issue of Energy Engineering presents selected contributions from the 2024 Conferences on Sustainable Development of Energy,Water and Environment Systems(SDEWES),reflecting recent advances in modelling,system integration,and technology deployment.The included papers address a broad spectrum of challenges relevant to integrated energy–water–environment systems.These include building-sector decarbonisation through hybrid heat pump configurations,geothermal revitalisation of existing oil and gas wells via deep borehole heat exchangers,and techno-economic comparisons of electrochemical batteries and supercapacitors for island energy systems.Further contributions investigate decentralised micro-hydropower solutions tailored to Amazonian conditions,advanced modelling of seepage characteristics in deep tight reservoirs accounting for creep effects,and multi-physical thermal modelling of lithium iron phosphate batteries for residential applications.In addition,hydrogen storage-supported energy system planning using detailed regional housing datasets and retrofit solutions for load balancing in legacy drilling-rig mud pump drives are explored.Collectively,the papers demonstrate how component-level innovation,data-driven planning,and system-level integration can jointly support flexible,resilient,and sustainable energy transitions.By covering diverse applications and geographical contexts,this Special Issue highlights the breadth of the SDEWES research community and provides insights that are relevant for researchers,system planners,and decision-makers working toward integrated energy–water–environment systems. 展开更多

Compressed carbon dioxide(CO2)energy storage(CCES)has emerged as a promising large-scale energy storage technology,characterized by high energy density,moderate critical temperature,and operational flexibility.Concurrently,carbon capture,utilization and storage(CCUS)technology represents a critical pathway toward carbon neutrality for energy systems.The integration of CCES with CCUS is attracting growing research interests due to its unique potential to synergize energy and carbon flows within a closed-loop framework.This paper provides a comprehensive literature review of technological advancements in CCES and offers a perspective on its integration with CCUS.First,the fundamental working principle,system configurations,key performance indicators,and emerging demonstration projects of CCES are introduced.Subsequently,cutting-edge research and key challenges of CCES system are reviewed,focusing on optimization of CO2-based mixed working media,efficient liquefaction of low-pressure CO2,development of low-cost and safe CO2 storage facilities,enhancement of system performance through integration,and evaluation of dynamic behaviors.A central focus is placed on the integration of CCES with CCUS,highlighting how this synergy transforms CCES from a pure storage technology into a multi-functional tool for carbon management.This integration enables infrastructure sharing,dual-function storage(for energy and CO2),and improved economics.Finally,this review identifies key directions for future research,including advancing efficient system integration,developing high-precision transient simulation models and dynamic control algorithms,ensuring long-term safety of geological reservoirs under cyclic injectionextraction operations,and establishing multi-objective optimization and multicriteria assessment frameworks to support the commercial deployment of integrated CCES-CCUS systems. 展开更多

The excellent electrical conductivity and superior cycling stability render Ti3C2 MXene a promising Li ion battery anode.Nevertheless,the practical implementation of Ti3C2 MXene in commercial applications faces significant challenges,predominantly due to the low specific capacity.MgH2,a typical hydrogen storage material,exhibits extraordinary lithium storage capacity,but it faces severe cycling stability issues.Aiming at combining the merits of both MXene and MgH2 while circumventing their drawbacks,we investigate the electrochemical performance of Ti3C2/MgH2 composites as anodes for lithium-ion batteries.The composites were synthesized by ball milling with varying mass ratios of Ti3C2 MXene and MgH2,followed by dehydrogenation-hydrogenation treatment for the optimized ratio.Structural and morphological analyses confirm the uniform distribution of MgH2 within the Ti3C2 matrix,with enhanced crystallinity and interfacial interactions after dehydrogenation-hydrogenation.The hydrogenated composite with the optimum ratio,named as MX/MH-5/2-res,exhibits superior electrochemical properties,including high initial discharge capacity (1416.3 mAh g-1),excellent cycling stability(434.4 m Ah g-1 after 140 cycles at 0.1 A g-1),and outstanding rate capability (217.1 mAh g-1at 5 A g-1).Cyclic voltammetry and electrochemical impedance spectroscopy reveal improved reaction kinetics and reduced charge transfer resistance (114.3Ω)due to enhanced interfacial binding between Ti3C2 and MgH2.Theoretical study unveils the underlying cause for enhanced Li interfacial binding through a combination of work function,charge density,and crystal orbital Hamilton population analyses.Our study paves the way for dehydrogenation-hydrogen initiation of the MXene/MgH2 composites to achieve high-performance lithium-ion battery anodes. 展开更多

Amidst escalating global energy demands and the depletion of fossil fuel reserves,there is an urgent need to develop energy storage materials derived fromlow-cost and sustainable biomass.Lignin,an abundant aromatic polymer,has gained increasing recognition as a highly promising precursor for electrode materials due to its low cost,high carbon content,and rich functional groups.For electrochemical energy storage applications,lignin-derived carbon materials,including porous carbon,carbon fibers,and carbon aerogels,demonstrate considerable potential as effective electrodes.This review provides a comprehensive summary and analysis of recent advances in the field.It systematically elaborates on the types of lignin-based carbon materials,their preparation methods,as well as their microstructures and porosity.The application performance of these materials as carbon electrodes in batteries and supercapacitors is thoroughly examined.Furthermore,the review analyzes and summarizes the relationships between structure-performance,and highlights the current research progress and challenges associated with their preparation.Finally,it discusses the existing challenges in utilizing lignin-based carbon electrodes for electrochemical energy storage and explores their potential integration with emerging green technologies and novel theoretical approaches.By offering a critical perspective on these aspects,this review aims to provide valuable insights and strategic directions for future breakthroughs in the development of lignin-based energy storage materials. 展开更多

This paper proposes a hybrid energy storage control method that coordinates the minimum output of the wind-storage system and the SOC self-recovery capability,applied to stand-alone energy storage stations.Under the premise of meeting the wind power smoothing requirements,model predictive control(MPC)is employed to rapidly regulate the SOC and output of the energy storage system during the smoothing process,thereby enhancing its sustained and stable operation capability,and decomposing the original wind power into a direct grid-connected component and a hybrid energy storage smoothing component.Subsequently,the Northern Goshawk AlgorithmImproved Complete Ensemble Empirical Mode Decomposition with Adaptive Noise(NGO-ICEEMDAN)method is employed to decompose and reconstruct the hybrid energy storage power obtained from MPC rolling optimization by determining the optimal combination of white noise amplitude weight Nstd and the number of noise additions(NA),and to allocate the reconstructed power between the supercapacitor and the battery.Finally,simulation verification is conducted using actual 10o MW wind power data from a site in Inner Mongolia.The results demonstrate that the proposed strategy can coordinate the relationship among the minimum output of the hybrid energy storage system(HESS),SOC balancing,and grid-connected power fluctuations.The NGO-ICEEMDAN method enables more precise power allocation,thereby improving the rationality and efficiency of energy management in wind power hybrid energy storage systems. 展开更多

Understanding the wettability of carbon dioxide(CO2)and the interfacial properties between reservoir rocks and fluids is crucial for the effective geological carbon sequestration(GCS).The most accurate way to measure these properties is the laboratory experiments under simulated reservoir conditions.However,experimental measurement of CO2wettability in storage/caprock,influenced by thermo-physical conditions,poses significant challenges due to the reactivity and embrittlement risks associated with high levels of CO2.Therefore,data-driven machine learning(ML)models can be used as an alternative to laboratory experiments to predict rock/CO2/brine wettability in a precise and less hazardous manner.In this study,we have used multiple ML models,including stacked generalization regression(SGR),gradient boosting,and tree-based models,to estimate the wettability of Saudi Arabian(SA)basalt within a ternary system involving rocks,CO2,and brine,operating under diverse conditions.To improve the accuracy of the ML models,a comprehensive set of experimental data was collected from the literature that covered a wide range of pressure and temperature,0.1–25 MPa and 298–343 K,respectively.Various data exploration methods,such as heatmaps,and histograms were used to thoroughly examine the laboratory dataset.The ML models were trained to predict the advancing and receding contact angles.The results showed that the proposed ML models could accurately forecast wettability behaviors across diverse operational conditions with an average R2 score of above 0.996.The outcomes of ML models can be highly useful for accurately determining the CO2wettability.This information is crucial for defining the storage capacity and assessing containment security in large-scale CO2sequestration projects. 展开更多
