Therefore, the development of the hydrogen sector must be accompanied by the update of calculation methods in order to take into account hydrogen specificities (extremely flammable product, specific physico-chemical properties) or the conditions of the new use cases (cryogenic hydrogen storage, high distribution pressure, etc.).
For example, the storage of hydrogen in a liquid form, with a temperature close to absolute zero, leads to the specific consideration of cryogenic impact.
“Unlike the development of the latest aircraft (A350, A320neo), for the hydrogen aircraft, we are starting almost from scratch.”
This work is also accompanied by updates and developments of new tools, the validation needs of which are carried out in parallel by setting up experimental tests and studying scientific publications. The research focuses in particular on several areas such as hydrogen combustion, structural strength, cryogenic aspects, etc. The use of hydrogen can be seen as a challenge because of its use in extreme conditions, from cryogenic storage temperatures to more violent combustion/explosion. This is a real exploration in the field of physics.
