Summary: Hydrogen storage in underground structures is a vital way to maintain the balance between energy production and consumption, with the potential to convert excess electrical energy into chemical energy for temporary storage. The study found that using methane as cushion gas could achieve a maximum hydrogen recovery rate of 89.7%, while absence of cushion gas led to a higher hydrogen loss.

Summary: The study shows that acidity has a significant impact on the composition of ambient particles. A new thermodynamic analysis method has been developed to estimate aerosol acidity. Analysis of historical fog water composition data in the Po valley in Italy suggests that the aerosol is mildly acidic, with a decreasing trend in pH over the last few decades.

Summary: Depleted shale reservoirs have the potential to serve as long-term geological storage sites for CO2. However, the complex heterogeneity of shale matrix poses challenges in understanding CO2 transport behavior. In this study, a flow-coupled-geomechanical model is developed to analyze CO2 transport at the microscale, considering the deformation and interactions of both organic matter (OM) and inorganic matter (iOM). The results show that heterogeneity in the shale matrix leads to regional differences in CO2 transport and shale matrix deformation behavior, emphasizing the importance of considering matrix heterogeneity.

Summary: An accurate estimate of CO2 storage capacity is crucial for designing a CCS project. This study presents a simple volumetric equation for estimating CO2 storage capacity in depleted gas reservoirs and investigates its validity and limitations through numerical reservoir simulation. The study found that the volumetric equation provides a consistent estimate of CO2 storage capacity compared to numerical simulations, especially in reservoirs with weak or moderate aquifer support.

A biogeochemical model considering reservoir environment factors has been developed and validated. The study reveals the effects of reservoir parameters and injection parameters on biomethanation efficiency, and suggests utilizing geothermal energy and pre-injecting highly active methanogens to improve efficiency.

Summary: The study focuses on developing algebraic block preconditioners for efficient solution of linear systems arising from a three-field mixed finite element approximation of Biot's poroelasticity equations. The proposed methods utilize approximate inverse-based techniques to decouple the original system of equations and obtain explicit sparse approximations of the Schur complements related to the physics-based partitioning. These methods have been tested in various numerical experiments, including applications in petroleum and geotechnical engineering.

Summary: Global recognition of groundwater aquifer depletion and attention to land subsidence effects related to aquifer exploitation. Study developed LSIE index based on 10 land subsidence attributes and applied it to 113 sites globally. Findings show impact of LSIE varies with changes in natural processes, regulatory policy interventions, and groundwater usage, with effectiveness of interventions depending on aquifer lithology. Developing countries are more vulnerable to land subsidence due to lower water governance and institutional performance.

Summary: Many studies have shown the sensitivity of our environment to manmade changes, particularly the impact on atmospheric and hydrological processes. The effect on Solid Earth processes like subsidence is not as straightforward, but in the Dead Sea region, the climatic forcing is strong and freshwater overuse is massive. Observations over a 3-year period have linked high evaporation and subsequent drop in the Dead Sea lake level with high subsidence rates, revealing a synchronous behavior with atmospheric and hydrological changes with a two-month time lag.

Summary: This paper presents a preconditioning framework for the coupled problem of frictional contact mechanics and fluid flow in the fracture network. A blended finite element/finite volume method is used to discretize the porous medium, and cell-centered Lagrange multipliers are employed to represent the contact constraints. The fluid flow in the fractures is described by a classical two-point flux approximation scheme. The authors aim to design scalable preconditioning strategies based on block partitioning of the unknowns and multigrid techniques.

Summary: The study proposes a method that integrates fuzzy set theory and weighted Bayesian model to evaluate the hazard probability of land subsidence in Beijing. Results show that groundwater overpumping leads to high land subsidence hazard probabilities in the Chaobai River alluvial fan area, but the overall hazard probability decreased due to lower rates of groundwater level decrease. This study provides useful insights for decision makers in selecting different approaches for land subsidence prevention.
