Summary: Underground gas storage (UGS) facilities in the United States can store a large amount of pure hydrogen, making them a promising option for underground hydrogen storage. Transitioning UGS infrastructure to hydrogen could significantly reduce the need for new hydrogen storage facilities. The UGS facilities can buffer a significant percentage of the projected hydrogen demand for 2050, surpassing the current role of storage in buffering natural gas demand.

Summary: Underground hydrogen storage is critical for future hydrogen infrastructure to ensure supply flexibility and security. Storage in porous reservoirs should be used in combination with salt caverns to meet high storage capacity requirements. A case study of hydrogen storage in a depleted gas field in the Netherlands evaluated its techno-economic feasibility. The study assessed different surface facility designs and calculated the levelized cost of hydrogen storage. The study found that using nitrogen as cushion gas resulted in a lower cost of storage.

Summary: In this study, we investigated the phenomenon of water upconing to the hydrogen withdrawal well in underground hydrogen storage (UHS) reservoirs using both analytical solution and numerical simulation. The results showed that horizontal permeability is the main parameter controlling the height of upconing, and injection/withdrawal cycles can mitigate this phenomenon. Reservoirs with high horizontal permeability are preferred for avoiding upconing, and minimizing withdrawal rate and maximizing the distance from well to gas-water interface or the length of the perforated well interval are important engineering controls to minimize upconing.

Summary: Geological hydrogen storage can be used to address supply and demand imbalances in renewable energy sector and support the transition to low carbon emissions. We assessed the suitability of 75 depleted gas fields on the UK continental shelf for hydrogen storage based on microbial risk and suggested 9 no-risk and 35 low-risk gas fields as suitable candidates. Avoidance of high-risk gas fields and consideration of renewable energy production centers and repurposable pipelines led us to identify Southern North Sea as the most suitable region for hydrogen storage. Our study provides site selection guidance for geological hydrogen storage in the UK and offers a methodology applicable globally.

Summary: This study investigates the wetting ability of hydrogen on clay surfaces in the presence of brine. It found that all clay surfaces exhibited water-wetting behavior, which is beneficial for the injection and retrieval of hydrogen. However, the predominant water wettability of clays may lead to biogeochemical reactions and affect porosity and permeability.

Summary: This study investigated the impact of pyrotechnic ignitors on pressure trends and temperature distributions in 20 L and 1 m(3) standard test vessels, showing that igniter explosions in the 20 L vessel lead to a significant increase in pressure and a more rapid and uniform diffusion of temperature compared to the 1 m(3) vessel. The flame propagation generated by the ignitors in the 20 L vessel is relevant, resulting in overdriving phenomenon and higher deflagration index values for many organic dusts measured in the 20 L vessel compared to the 1 m(3) vessel. Additionally, CFD simulations indicate that the hot core dissipates faster in the 20 L vessel due to its higher turbulence level, making dusts controlled by particle heating more prone to combustion in the 1 m(3) vessel.

Summary: In this study, a three-layers theoretical model inspired by Mallard-Le Chatelier is developed to comprehensively describe the steps of flame propagation in combustible dusts/air. The model assumes that the dust flame propagation follows a homogeneous path, where the dust-air mixture is pre-heated until volatiles are produced, and these volatiles enter the combustion zone after being heated to the ignition temperature. The flame burning velocity is determined by the coupling between heating rate, pyrolysis and/or evaporation/sublimation rate, and volatiles combustion rate. The formation rate of volatiles is measured using TG/DSC analysis, and the laminar burning velocity of gases is computed by simulating gas flame propagation in a tube based on measured gas compositions.

Summary: Formates are promising salts for hydrogen storage, capable of catalytically converting to bicarbonate and being regenerated under moderate pressure. However, there are still challenges to be addressed, such as reaction kinetics, stability, cyclability, and increasing energetic density. This work critically reviews the current state and highlights theoretical limitations and applicative shortcomings, providing perspective on future research. Despite the existing bottlenecks, there is promising room for improvement, with state-of-the-art catalytic systems potentially reaching 72% energetic efficiency, which could be improved up to 90%.

Summary: According to international standards, achieving a uniform distribution of dust particles within standard vessels is crucial for accurate evaluation of explosion and flammability parameters. CFD simulations reveal that the particles are mostly concentrated at the edges of the macro-vortices generated by fluid and particle injection, leading to incomplete feeding and sedimentation phenomena. This can result in misleading measurements of flammability/explosion parameters. The aim of this study is to evaluate the key parameters affecting sedimentation and incomplete feeding in a 20 L vessel and propose a correlation for data correction.
