Hydrogen Separation Distances

[Guilherme Tell]

Hi All, I saw a thread here with the same concern that I have, however I could not see any answer. Does anyone can help me?
"Looking at general guidance for separation distances for hydrogen systems and skimming through the NFPA hydrogen guidance. For Gaseous hydrogen storage, NFPA 2 and 55 have the same tables which relate pressure, pipe diameter and hazard category to minimum separation distance. The tables that are present only go up to 2" however. How do you apply this guidance to systems with pipe sizes >2"? What about separation distances for equipment more generally? "

What about separation distances for equipment more generally? "

What do you actually mean storage? And the distance from what to what? In general it depends on the jurisdiction and equipment type.

Factory Mutual's Property Loss Prevention Data Sheet 7-91 table 2.1.2.6.
AIGA's standard 87/20 para. 6.2.2
EIGA IGC's standard 75/07 app. B or 15/21 para. 6.2

The question is too vague to response.

Note that the referenced series exist for fuel hydrogen handling, e.g. start with ISO/TR 15916.
