Characterization and assessment of hydrogen leakage mechanisms in salt caverns. [PDF]
Sci RepAbstractSalt caverns are widely regarded as a suitable option for the underground storage of hydrogen. However, an accurate assessment of the hydrogen leakage through the walls of salt caverns into the surrounding formations remains crucial. In this work, the flow of hydrogen into the surrounding formation is evaluated by assuming that salt rock ...

Numerical simulation study on hydrogen leakage and explosion of hydrogen fuel cell buses. [PDF]
Sci RepThis study explores the safety problems of hydrogen leakage and explosion in hydrogen fuel cell buses through Computational Fluid Dynamics simulations. The research investigates the diffusion behavior of hydrogen in the passenger cabin depending on the leakage position and flow rates, identifying a stratified, constant-concentration layer formed at the

Electrochemical Sensor for Hydrogen Leakage Detection at Room Temperature. [PDF]
Sensors (Basel)The use of hydrogen as fuel presents many safety challenges due to its flammability and explosive nature, combined with its lack of color, taste, and odor. The purpose of this paper is to present an electrochemical sensor that can achieve rapid and accurate detection of hydrogen leakage.

Climate consequences of hydrogen leakage [PDF]
, 2022 Abstract. Hydrogen is quickly gaining attention as a “clean” fuel that can support a transition to a decarbonized energy system. Given the urgency to decarbonize global energy systems, governments and industry are moving ahead with efforts to increase hydrogen technologies, infrastructure, and applications at an unprecedented pace, including billions ...
