A quantity of gas is introduced into a gas reservoir via a filling station provided with a filling line. The quantity is measured. A signal is generated indicating a corrected quantity of transferred gas. The signal is obtained by adding a predetermined, positive or negative, corrective amount to the measured quantity of gas transferred.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with an exhaust nozzle corresponding to a vehicle exhaust port. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. A first pipe may be configured to transport captured exhaust therethrough from the exhaust nozzle to. The captured exhaust may be at least temporarily stored in an exhaust holding tank connected to and in fluid communication with the first pipe

A gas discharge device, for a vehicle powered by compressed gas, includes: a gas manifold having a hollow body and including at least one port configured to be in fluid communication with a compressed gas tank, and an opening for discharging gas into the atmosphere; and a pipe configured to connect the port to the compressed gas tank. The pipe is freely translatable in the port to enable a first end of the pipe to move translationally along an axis in the port.

A system for cryogenic gas delivery includes a cryogenic tank configured to contain a cryogenic liquid and a gas within a headspace above the cryogenic liquid. The system also includes first and second vaporizers and a use outlet. A first pipe is configured to transfer gas from the headspace through the first vaporizer to the use outlet. A second pipe is configured to transfer liquid from the tank through the first vaporizer so that a first vapor stream is directed to the use outlet. A third pipe is configured to build pressure within the tank by transferring liquid from the tank through the second vaporizer so that a second vapor stream is directed back to the headspace of the tank. A first regulator valve is in fluid communication with the second pipe and opens when a pressure on an outlet side of the first regulator drops below a first predetermined pressure level. A second regulator valve is in fluid communication with the third pipe and opens when a pressure inside the tank drops below a second predetermined pressure level. The first predetermined pressure level is higher than the second predetermined pressure level.
