Hydrogen’s property as a low-density gas makes it particularly tricky as a diesel replacement. For hydrogen to be useful as a truck fuel, it must either be compressed or liquified (see the call-out box on hydrogen’s properties), making refueling complex. Hydrogen fueling station major components include high-pressure compressors, hydrogen storge pressure vessels, hydrogen gas chillers and high-pressure gas dispensers. In all cases, this technology is actively developing and the method(s) for hydrogen storage and dispensing to trucks continues to evolve. The following are considerations for hydrogen storage, delivery and dispensing from the fueling station to the vehicle, including tradeoffs as the technologies mature. ​
