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).
