Modes of Storage
? In fuel cell applications where the power source is mobile, such as automotive or portable usage, a hydrogen carrying fuel reservoir is needed.
? For stationary applications, where the fuel cell can be attached to a natural gas or hydrogen pipeline, storage is not as critical.
? In automotive applications, there needs to be a hydrogen fuel tank capable of achieving approximately the same total driving range as the gasoline tank it replaces with at least comparable volumetric and gravimetric energy densities. This turns out to be a difficult challenge.
? Gasoline is a high-energy content, high-density liquid that can be stored at atmospheric pressure.
? Hydrogen also has a molar high-energy content but a very low density as a gas phase.

HYDROGEN DELIVERY
Gas versus Liquid Truck Delivery: a compressed hydrogen gas delivery truck carries
around 530 kg of hydrogen in the gas phase (or about 60–70 hydrogen PEFC car fuel
tanks), or 3370 kg (about 425 tanks) in the liquid phase. Gas-bottle hydrogen delivery
is limited to small laboratory volumes and short travel distances.
Pipeline Delivery Where long distances are involved, hydrogen delivery by pipeline
can be the most efficient means for transporting the fuel, similar to the way petroleum
or natural gas is shipped throughout the world. Pipeline delivery of hydrogen can take
place by three methods:
1. Gas-phase hydrogen pipelines
2. Cryogenic liquid hydrogen pipelines
3. Hydrogen carrier pipelines
