The Polytechnic University project "Methodology for Assessing Hydrogen Embrittlement of Pipe Steels" won the All-Russian scientific and technical competition "Hydrogen Technoleaders" in the "Hydrogen Energy" category.
Hydrogen is being called the fuel of the future. Hydrogen energy projects have already been launched in Russia, focusing on the development of electrolysis technologies, solar energy, and the construction of production stations and transportation infrastructure, including for pressurized gaseous hydrogen.
One of the risks of hydrogen energy infrastructure projects is materials. The use of widely used steels requires confirmation of their resistance to hydrogen embrittlement, while the use of non-metallic materials and coatings requires studies of hydrogen density and permeability.
For the fifth year, the team from the New Technologies and Materials Scientific and Technological Complex at SPbPU (A. S. Tsvetkov, S. E. Dagaev, A. I. Kolotiy, A. D. Evdokimov, O. V. Molina), together with industrial partners from the metallurgical and oil and gas sectors, has been developing test methods and conducting research on steels and coating materials directly in a high-pressure hydrogen-containing gas environment, as well as with their preliminary saturation with hydrogen.
Pipeline transport is being considered for transporting hydrogen and/or methane-hydrogen mixtures. Given the range of pipes used, steel grades, and operating conditions, continued research is essential for the future of hydrogen energy. A prototype of a new research facility for assessing crack resistance was presented at the competition, along with the results of previous work conducted using unique methods on developed test rigs. "Winning the competition is recognition of our work and confirmation that the chosen approach is in demand and truly important for the future of hydrogen energy," said Anton Tsvetkov, project manager for the New Technologies and Materials Scientific and Technical Complex at Polytechnic University.
