Abstract

In one aspect, an insert including a single metal or alloy compatible with cryo-compressed tanks is disclosed. In one embodiment, the insert contains one, two, or more tubes that extend into the inner storage volume of the tank. The insert may be integrally formed with the tubes. The tubes enable the entrance and exit of hydrogen to the inner storage volume. In one embodiment, the tank includes a boss suitable to accept the insert. The boss and the insert may be the same metal. The insert may minimize the number of welds suitable for use in on-board heavy duty storage applications. Overall, this type of insert decreases the probability of hydrogen leaks, reduces the cost of the insert as only one piece is required, and leads to faster manufacturing as fewer welds are required.
