Gas Cylinders and hydrogen storage
Gas Cylinders and hydrogen storage
(OP)
I'm looking for some guidelines (manufacture, testing, maintenance etc) covering steel gas cylinders for hydrogen storage for 10-20 MPa, ambient conditions.
The Sandia website had some interesting information (although no practical tips or guidelines):

From what I've read, hydrogen is a concern for high tensile steels and welded regions (embrittlement) but the effects on low carbon steels are milder (although not necessarily negligible).
Is the standard test regime, done for cylinders containing more noble gases (N2, He), enough?
Any help appreciated.

RE: Gas Cylinders and hydrogen storage
The elemental hydrogen will migrate into a weld void, then combine to create molecular hydrogen. It is then too large to migrate out and creates a pressure within the void.
Does someone have these types of cylinders off the shelf?

You can Google
"steel cylinders for high pressure hydrogen storage" and receive numerous hits on articles, guidelines, and actual lecture for advanced materials.
