NPL | International landscape on Cryogenic and Hydrogen Materials testing

The infrastructure should be inclusive of cryogenic

and in-situ liquid hydrogen testing as well as in-situ gaseous hydrogen testing. More

specifically:

* For cryogenic testing, there is an immediate need for both capability and capacity

to cover the increasing demand for evaluation of mechanical and thermal

properties of materials at 20 K.

* For in-situ liquid hydrogen testing, there is an immediate need for research-based

testing facilities i.e., utilising small-scale hydrogen liquification including in-situ, to

boost materials research and innovation, followed by investment in large-scale

facilities like those at NASA Marshall Space Flight Center (MSFC).

* For in-situ gaseous hydrogen testing, the coordination of existing facilities must

be prioritised together with an increase of current capability to higher pressures

and temperatures similar to those at Sandia Laboratories.
