Dominion Gas operates 11,000 gallon containers for long term shipment and storage of liquid helium.
The containers are cylindrical and housed in a standard 8ft x 8.5ft x 40ft ISO modular frame. The container consists of an inner helium container, which is thermally shielded from the surroundings by a liquid nitrogen shield combined with a high vacuum and a rugged, protective outer vessel.
These containers are capable of transporting 38,000 litres of liquid helium (equivalent to 28,320m3 of gaseous product) with a 30 day no loss hold time.
Helium can be stored as a gas or as a cryogenic liquid. The most efficient way to transport helium is as a cryogenic liquid.
