Institute of Materials and Mechanics of Machines SAS, v. v. i., is part of the hydrogen embrittlement research within the H2INSOL project.

The Institute of Materials and Mechanics of Machines SAS, v. v. i., (ÚMMS SAS, v. v. i.) is the principal investigator of the project entitled "Decarbonizing with Hydrogen: Innovative Alloys for Storage Solution and Sustainable Future" (acronym " H2INSOL) from the project call Decarbonization of Economics, which focuses on the investigation of hydrogen embrittlement in modern complex concentrated alloys (CCAs). The research aims to investigate the influence of hydrogen and its diffusion mechanism on the microstructure of these materials and their resistance to hydrogen embrittlement to optimize these properties and select alloys suitable for hydrogen applications.
 
The project was launched in January 2025 and aims to investigate the influence of various precipitates and grain boundaries in CCA alloys on hydrogen diffusion and its impact on deformation and fracture mechanisms. In addition, the research team at the Institute of Microstructures of the Slovak Academy of Sciences, v. v. i., will also focus on comparing the behaviour of different types of microstructures, namely single-crystal and columnar. The main goal is to analyze the behaviour of hydrogen in these CCA alloys in detail.
 
The project's principal investigator is Dr. K. Kamyshnykova from the Institute of Microstructures of the Slovak Academy of Sciences, v. v. i. The Renewal Plan for Slovakia funds the project.
 
"Our goal is to better understand the mechanisms of hydrogen embrittlement at the macro, micro and nano levels, and at the same time, provide the industry with reliable information for the development of new materials for hydrogen storage," said Dr. K. Kamyshykova
 
In January, an introductory meeting of the project partners was held at the Institute of Microstructures of the Slovak Academy of Sciences, v. v. i. The researchers' presentations were followed by a discussion of the research goals and the project schedule for the next period.
 
The H2INSOL project is an important step towards sustainable and safe energy solutions. The research results will benefit industrial applications, such as high-pressure hydrogen storage.
