Caractérisations thermo-physiques des matériaux à -250°C
THEMACS Ingénierie presents a Workshop on the thermophysical properties of materials
The storage of liquid hydrogen represents a major technical challenge, requiring an in-depth understanding of the thermophysical properties of materials at extremely low temperatures, often close to -250°C. Hydrogen, as an energy-dense gas, is seen as a promising energy carrier for a sustainable future, particularly for the transition to cleaner energy sources. However, to fully exploit its potential, efficient and safe storage solutions are essential.
At cryogenic temperatures, the physical characteristics of materials can change radically, influencing their performance and reliability. For example, mechanical properties such as strength and ductility are crucial to ensuring the structural integrity of storage tanks, while thermal properties such as thermal conductivity and heat capacity affect insulation requirements and energy losses in the form of heat. Identifying and characterising materials capable of maintaining their properties under these extreme conditions guarantees not only the safety of storage, but also the economic and technical efficiency of the overall process. In-depth knowledge of the thermophysical behaviour of materials at cryogenic temperatures is therefore essential for the development and optimisation of liquid hydrogen storage systems. In the context of growing demand for sustainable energy solutions, this understanding is a cornerstone for technological progress in the field of hydrogen.
