5. Weaknesses & Limitations (To Be Aware Of)

• Piping (onshore plant/refueling station piping, above ground)
• Pipelines (transporting hydrogen over land, buried or above ground)
• Operating temperatures from -253°C (20 K, liquid H₂) to 150°C (423 K)
• Pressure ranges – no upper limit, but design follows Chapter IX of ASME B31.12.
