Transportation


Transportation of Liquid Hydrogen
Liquid hydrogen (LH2) is formed at at 21.2 K (-251.95° C) and requires an energy intensive cooling process along with cryogenic tanks for storage. Certain specialized application that require liquid hydrogen, it can be transported in special tankers.Road tranportation of hydrogen
Hydrogen is currently being transported in both liquid and as a compressed gas using special tanker trucks. This mode though will continue to be limited as a method of delivering fuel to end users or distribution depots from a central processing or storage facility.

Storage

Hydrogen is the lightest and most abundant element in the universe. It forms the basis of all organic compounds, living things and is present in the essence of life - water. There are three main ways that hydrogen can be stored - as a compressed gas, in liquid form, in metal hydrides and in carbon nanotubes.

Compressed Hydrogen Gas
Hydrogen gas can be compressed and stored in storage tanks that can hold it at the required pressure. The tanks can either be made with steel, aluminium or copper alloys that may be encased in fibreglass The steel tanks are most often used for static applications where weight is not a hindrance as the steel tanks tend to be heavy. High pressure tanks also appear in some test automobiles. but safety and space remain significant concerns. The tanks tend to be big and bulky with the ongoing concern regarding a leak.
