Cryogenic liquefied gases are dense and occupy less space than compressed gases. This enables efficient transportation and storage.
Taking hydrogen as an example, the payload of a 40 tonne tube-trailer road vehicle with steel compressed gas cylinders is around 300kg of hydrogen. Using cryogenic liquid hydrogen distribution, a road tanker of a similar size can transport about three tonnes of hydrogen, 10 times more than the compressed gas trailer.
When considering the number of vehicles required to deliver hydrogen from a production site to customers, compressed gas deliveries would need ten times the number of driven kilometres. In the worst case, that would also mean ten times as many vehicles and ten times as many qualified heavy goods vehicle drivers. The operating costs of running a cryogenic distribution fleet can be significantly less than using compressed gas tube trailers.
