A Review of Underground Hydrogen Storage in Depleted Oil and Gas Reservoirs

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
As hydrogen assumes an increasingly strategic role in the global energy transition, the development of efficient, safe, and cost‐effective large‐scale hydrogen storage systems has become a critical enabler for the hydrogen economy. Underground hydrogen storage (UHS), particularly in depleted oil and gas reservoirs, is gaining traction as a promising ...

A comprehensive histomolecular characterization of meningioangiomatosis: Further evidence for a precursor neoplastic lesion

Brain Pathology, Volume 34, Issue 6, November 2024.
Clinical and molecular history of meningioangiomatosis. Abstract Meningioangiomatosis (MAM) remains a poorly understood lesion responsible for epileptic disease. In the past, MAM was primarily described in the context of neurofibromatosis type 2 before being mainly reported sporadically.

Preliminary Evaluation of the Influence of Hydrogen on the Fracture Toughness of an X65 Gas‐Transmission Pipeline Steel

Advanced Engineering Materials, Volume 26, Issue 16, August 2024.
We measured two values of fracture toughness for X65 steel in air (KQ of 369 and 487 MPa√m$\sqrt{} \text{m}$) and two essentially American Society for Testing of Materials–valid values of fracture toughness of KJ1C of 150 and 189 MPa√m$\sqrt{} \text{m}$ for X65 subjected to in situ hydrogen charging thought to be equivalent to a hydrogen gas pressure ...

Full‐scale testing of near‐neutral pH stress corrosion cracking growth behavior of a vintage X52 oil pipe

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 5, Page 1638-1655, May 2024.
Abstract This study presents an experimental investigation conducted on a 40‐year‐old vintage X52 oil pipe segment to assess the growth behavior of near‐neutral pH stress corrosion cracking (SCC). Six cracks were introduced on the pipe specimen, each of which was associated with a unique combination of metallurgical and environmental condition.

Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Effect of hydrostatic pressure on the anodic dissolution process of X80 steel

Journal of Materials Research and Technology
Based on the fact that hydrostatic pressure affects chemical potentials of reaction species and the structure evolution of electric double layer (EDL), the authors propose a generalized-BV equation to analyze the anodic dissolution process of X80 steel in deep-sea environment.

Carbon Dioxide Corrosion Mechanisms: Historical Development and Key Parameters of CO2‐H2O Systems

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
The recent failures in flexible pipes have motivated the exhaustive research of corrosion mechanisms on high‐strength carbon steel armor wires that are the main structural compounds of those structures that mostly operate in seawater environments in the presence of carbon dioxide (CO2) and confined spaces.
