Storage and transport

Unless the production of the hydrogen is located at the point of usage it has to be stored and transported. Transportation is done by either gas grids or – more commonly - in various types and sizes of tanks. Pressure ranges for storage tanks range from 20 bar for liquefied tanks up to 700 ... 1,000 bar for compressed gas vessels. Also liquefied hydrogen (LH₂) is playing an increasingly important role due to its high energy density. Its temperature of -253 °C creates additional challenges.

Depending on the physical state of the hydrogen (gaseous or cryogenic) various measurement solutions have to be used. WIKA can provide both solutions for gaseous and liquid hydrogen storage.
