Today, almost all hydrogen is produced on the site where it is to be used in a practice called captive use. This is particularly common at industrial sites where hydrogen is used in manufacturing processes. For some applications, though, hydrogen is delivered from off-site. The delivery method depends on the distance to be travelled.

● High-Pressure Tube Trailer
● Liquefied Hydrogen Tanker
● Mobile Refueler
Hydrogen has a very high energy content by weight (about three times more than gasoline), but a very low energy content by volume (about four times less than gasoline). As a result, storing
hydrogen—particularly within the size and weight constraints of a vehicle is an area of concern. All systems for storing and handling hydrogen are designed with safety.
