As the global economy moves toward net-zero carbon emissions, large-scale energy storage becomes essential to tackle seasonal nature of renewable sources. Underground hydrogen (UHS) offers a feasible solution by allowing surplus be transformed into and stored in deep geological formations such as aquifers, salt caverns, or depleted reservoirs, making it available for use on demand. This study thoroughly evaluates UHS concepts, procedures, challenges. paper analyzes most recent breakthroughs...
The transition from fossil fuels to carbon-neutral energy sources is necessary reduce greenhouse gas (GHG) emissions and combat climate change. Hydrogen (H2) provides a promising path harness in sectors such as transportation. However, regional economic analyses of various H2 production techniques are still lacking. We selected well-known fuel-exporting region, the USA's Intermountain-West (I-WEST), analyze carbon intensity demonstrate tradeoffs. Currently, 78% global comes natural coal....
Subsurface formations are promising for large-scale H2 storage, balancing the energy demand and supply. Wettability is vital in ensuring storage safety, efficiency, capacity, whereas noticeable discrepancies exist literature. This work reconciles these by revealing mechanisms of quartz wettability alteration with surface chemistry pressure using classical molecular dynamics simulation. We find that fully rigid substrate results much lower hydrophilicity than flexible hydroxyl group...
Hydrogen (H2) energy is a promising transition pathway from conventional fossil fuels to sustainable clean energy. However, H2 requires large storage capacity because of its low volumetric energy–density nature. Underground sites provide ample space for storage. In this work, we proposed general workflow select saline aquifers' optimal sites, considering the and operational efficiency. We developed comprehensive data set high-fidelity numerical simulations quantify effects geologic operating...

Recently, coalbed methane (CBM) has become one of the major unconventional gas resources in world. In 2017, US CBM proved reserves were estimated at 336 Billion Cubic Meter (BCM) while production was about 27 BCM. Coal formations possess unique characteristics that necessitate accurate characterization and fundamental understanding prevailing mechanisms. For instance, sorption processes require a comprehensive integrating factors such as pressure, temperature, moisture content, ash...
To reduce carbon emissions, hydrogen (H2) has been considered an important energy carrier, since its combustion only generates water. With the development of shale gas, depleted gas reservoirs might be good candidates for H2 storage. However, mechanism storage in is not clearly understood. Therefore, this work, we apply Monte Carlo simulation to analyze compositional distribution and phase behavior H2–shale (H2–SG) system under multiscale (bulk + nanoscale) conditions. Our molecular results...
Abstract Geologic storage of CO 2 and H are climate‐positive techniques for meeting the energy transition. While similar formations could be considered both gases, flow dynamics differ due to differences in their thermophysical properties. We conduct a rigorous pore‐scale study water/CO water/H systems at relevant reservoir conditions Bentheimer rock sample using lattice Boltzmann method quantify effects capillary, viscous, inertial, wetting forces during gas invasion. At conditions,...
Accurate rock elastic property determination is vital for effective hydraulic fracturing, particularly Young's modulus due to its link brittleness. This study integrates interdisciplinary data better predictions of modulus, combining mining, experiments, and calibrated synthetics. We used the microstructural insights extracted from images geomechanical facies analysis. Additionally, petrophysical well logs were correlated with shear wave velocity (Vs) modulus. developed a machine-learning...
Abstract By 2050, shale gas production is expected to exceed three-quarters of total US natural production. However, current unconventional hydrocarbon recovery rates are only around 20%. Maximizing this resource thus necessitates improved understanding the fundamental mechanisms underlying retention within nanoporous matrix. In study, we integrated molecular simulation with high-pressure small-angle neutron scattering (SANS), an experimental technique uniquely capable characterizing methane...
In the United States, hundreds of thousands undocumented orphan wells have been abandoned, leaving burden managing environmental hazards to governmental agencies or public. These wells, a result over century fossil fuel extraction without adequate regulation, lack basic information like location and depth, emit greenhouse gases, leak toxic substances into groundwater. For most these such as well depth is unknown unverified. Addressing this issue necessitates innovative interdisciplinary...
