Compressed hydrogen
Compressed hydrogen (CH2, CGH2 or CGH2) is the gaseous state of the element hydrogen kept under pressure. Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) is used for mobile hydrogen storage in hydrogen vehicles.[1] It is used as a fuel gas.

Infrastructure
Compressed hydrogen is used in hydrogen pipeline transport and in compressed hydrogen tube trailer transport.
gollark: What are the axes?
gollark: Well, your graph looks very graphical, I suppose.
gollark: Yes. It might not be possible to do anything but somehow optimize the genetic-algorithm-based approach then.
gollark: That sounds worrying.
gollark: If your problem actually is nice and differentiable - which it sounds like it *might* be, I think you're laying out cables or something? - then it should be a lot faster if you can use that instead of just moving around randomly.
