An offload system is provided. The offload system is configured to offload a target species stored in an onboard volume positioned onboard a vehicle to an offboard volume. In one aspect, the offload system includes an onboard system positioned onboard the vehicle and an offboard system positioned offboard the vehicle. The onboard system selectively allows the target species stored in the onboard volume to flow downstream to the offboard system, which includes the offboard volume. The onboard system, the offboard system, or both, include features that facilitate efficient and safe offloading of the target species from the onboard volume to the offboard volume.

A frangible closure coupling is used with or on pipe of a tank that contains a potentially dangerous fluid, such as liquid natural gas. The closure coupling mitigates the uncontrolled release of fluid from the tank in the event of a rupture of a pipe attached to the tank.

A method and system for mobile storage and dispensing of hydrogen (H.sub.2) for refueling H.sub.2-powered vehicles includes a compressor system having a plurality of compressor stages in fluid communication with at least a portion of manifold valves in locations between compressor stages. A booster compression stage positioned downstream of the compressor system is in fluid communication between at least two of the manifold valves. A plurality of H.sub.2 storage banks is positioned downstream of the compressor system and the booster compressor stage. Low-pressure H.sub.2 is pressurized by the compressor system and/or the booster compressor stage to a working pressure and stored within the H.sub.2 storage banks. Upon a decrease of the H.sub.2 in one or more of the H.sub.2 storage banks from the working pressure, the H.sub.2 is repressurized by the booster compressor stage. Also disclosed is a ground-based cryogenic tank and a method of manufacturing a ground-based cryogenic tank.

A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.
