TL;DR: In this article, the authors addressed the change in capacity and efficiency of underground gas storage facilities associated with the blending of hydrogen in the stored natural gas, the geological integrity of the reservoir and caprocks, the technical integrity of gas storage wells, durability of the materials used for well completions, corrosion and environmental risks associated with hydrogen products of microbial metabolism.

TL;DR: In this article, a numerical case study of a depleted gas reservoir was performed to predict injection and production rates, pressure response and composition of the produced gas stream, and the storage was charged with hydrogen for 5 years.

TL;DR: In this article, a mathematical model is presented which is capable to reflect the coupled hydrodynamic and bio-chemical processes in UHS and is numerically implemented by using the open source code DuMuX developed by the University of Stuttgart.

TL;DR: In this paper, the authors studied the geochemical, geochemical and petrophysical properties of the Rotliegend reservoir sandstones of the Altensalzwedel block in the Altmark area (Saxony-Anhalt, central Germany).

TL;DR: In this article, the authors show that the hydrodynamic behavior of underground hydrogen storage is very unique and different from that of a natural gas storage, which may cause significant losses of hydrogen.
