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 technology identifies special conditions needed its successful application, including site selection guidelines, technical factors, significance characteristics. The integrity wells caprock, which is important safe efficient storage, can affected operating dynamics cycle, notably fluctuations pressure stress within formations. To evaluate potential broader adoption, we also examined economic elements cost-effectiveness practicality storage. We reviewed current efforts identified key knowledge gaps, primarily areas hydrogen–rock interactions, geochemistry, gas migration control, microbial activities, geomechanical stability. Resolving these technological challenges, regulatory frameworks, environmental sustainability are UHS’s long-term extensive integration industry. article provides roadmap research development, emphasizing need further fully realize technology’s promise pillar economy.

Apparent kinetics is often used to describe a variety of reactions in the field chemical looping and solar thermochemical processes, yet rigorous analytical methodology for utilizing such has been lacking. The implementation novel approach was exemplified ceria cycle producing hydrogen, specifically H2O-driven oxidation step. H2 production rate equation derived, rearranging apparent from experimental data literature into more suitable form. 1D model integrates heat transfer, fluid dynamics, redox chemistry, providing description directly irradiated receiver–reactor. Model robustness ensured through oxygen mass balance across cycle, comparison against shows high agreement. can be useful simulating cycles using any nonstoichiometric oxide, as ceria-based oxides and, most importantly, oxidation-limited perovskites, which optimizing step terms flow, kinetics, reaction times crucial. proposed applied arbitrarily complex reactor geometries. inherently local nature also allows spatial distributions material’s conversion utilization obtained, paving way optimization strategies reactor’s design operation.

The Bohai Rim Region plays a crucial role in the economy of northern China. Historically, area’s development has been driven by resource-intensive industries, necessitating urgent structural transformation. In response, government actively promoted green economic model. This study evaluates efficiency performance and total factor productivity (TFP) across five provinces region, incorporating regional innovation capabilities outputs into input–output system. results show that (GEE) improved regions, with higher technological advancement leading to greater improvements TFP. Additionally, disparity between municipalities decreasing. indicates that, while inter-provincial differences are widening, intra-regional disparities narrowing. Meanwhile, this provides foundation for integration policymaking Rim, offering insights balancing growth environmental sustainability.
