Hydrogen can be transported in many ways that include:

  • As a pressurized gas in truck- or rail-mounted tanks.
  • In lower pressure metal hydride tanks.
  • As a cryogenic liquid in insulated tanks.
  • In pipelines.
  • Combined with other molecules to make other liquids and gases that can generally be less expensively transported (e.g., ammonia, methane, methanol, formic acid, and various hydrocarbons).
