With the long-standing efforts of green transition in our society, underground hydrogen storage (UHS) has emerged as a viable solution to buffering seasonal fluctuations renewable energy supplies and demands. Like operations hydrocarbon production geological CO2 storage, successful UHS project requires good understanding subsurface formations, while having different operational objectives practical challenges. Similar situations problems, information formations at field level cannot be obtained through direct measurements due resulting high costs. As such, there is need for characterization monitoring scale, which uses certain history matching algorithm calibrate numerical model based on available data. Whereas have been widely used activities better reservoirs, best knowledge, present it appears relatively less touched area problems. This work aims narrow this noticed gap, investigates use an ensemble-based workflow 3D case study. Numerical results study indicate that works reasonably well, also identifying some particular challenges would relevant real-world

Underground Hydrogen Storage (UHS) has gathered interest over the past decade as an efficient means of storing energy. Although a significant number research and demonstration projects have sought to understand associated technical challenges, it is yet be achieved on commercial scales. We highlight case studies from town gas blended hydrogen storage focusing leakage pathways reactivity. Experience helium serves analogue for containment security two gases share physiochemical similarities, including small molecular size high diffusivity. Natural are also investigated, well integrity safety challenges. Technical parameters identified having adverse effects security, efficiency, reactivity were then used develop high-level site-specific screening criteria. Thirty-two depleted offshore hydrocarbon reservoirs in UK Continental Shelf (UKCS) potential formations based application our The screened fields reflect large energy capacities, low cushion requirements, proximity wind farms, thereby highlighting widespread geographic availability UHS UKCS. Following initial screening, we propose that analysis existing concentrations investigation local tectonic settings key criteria identifying stored hydrogen.

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.

Hydrogen storage is crucial to developing secure renewable energy systems meet the European Union's 2050 carbon neutrality objectives. However, a knowledge gap exists concerning site-specific performance and economic viability of utilizing underground gas (UGS) sites for hydrogen in Europe. We compile information on UGS assess potential capacity evaluate associated current future costs. The total Europe 349 TWh working (WGE), with capital costs ranging from $10 million $1 billion. Porous media salt caverns, boasting minimum 0.5 WGE, exhibit levelized $1.5 $0.8 per kilogram hydrogen, respectively. It estimated that can potentially decrease as low $0.4 after three experience cycles. Leveraging these techno-economic considerations, we identify suitable sites.

Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of in these geological formations is considered valuable option. However, high molecular diffusion from sites major concern. In this paper, idea through caprock during was investigated using series one- three-dimensional numerical models. models, overlying were as semi-infinite system, while interaction between reservoir defined by pressure composition at boundary. Hydrogen based on chemical potential differences influence pre-diffused hydrocarbon considered. Furthermore, analogies related partial differential equations spontaneous imbibition processes, simple yet accurate semi-analytical solution proposed. The presented be used to predict cumulative loss over time. This states that increases proportionally with square root Using solution, criterion indicates fraction lost given results obtained fluxes showed underestimated if existence ignored. analysis also indicated directly proportional interface rock exposed hydrogen, porosity, saturation caprock, coefficient, While presence facilitates diffusion, thermodynamic effects pressures lead comparatively lower molar density than matrix. Thus, final injected expected higher pressures.
