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 device for transferring a fluid from a supply tank to a receiver tank includes at least one duct for charging the receiver tank with liquid and at least one duct for return of the gas. The gas return duct is configured to transfer the gas contained in the receiver tank at a pressure close to or significantly different from the pressure of the supply tank.

An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

An air reservoir system is provided that includes a switchable valve to direct input air to an air reservoir, or stored air in the air reservoir to a firing pathway. Various example embodiments of the present general inventive concept may also include an air-saver system to maintain a minimum air pressure in the air reservoir during a firing operation.

Device for feeding fuel gas to an application (6), the device comprising at least one fuel gas bottle (1) furnished with a tap (2), and a bleed-off apparatus (4, 13) comprising an electronic logic unit (9) and a bleed-off outlet (4) selectively connectable to the tap (2), the bleed-off outlet (4) being linked (5) fluidically to an application (6) receiving the fuel gas originating from the bottle (1), the tap (2) comprising an electronic manometer (3) for measuring the pressure in the bottle (1), the electronic manometer (3) being devoid of battery and comprising an inductive member (7) for wirelessly transmitting to the electronic logic unit (9) information relating to the measured pressure, characterized in that the bleed-off apparatus (4, 13) also comprises an inductive member (8) powered electrically by the electronic logic unit (9) and in that, when the bleed-off outlet (4) is connected up to the tap (2), the inductive member (8) of the bleed-off outlet (4) is situated in a manner adjacent to the inductive member (7) of the manometer (3) so as to ensure electrical power supply of the manometer (3) by inductive coupling.

A liquefied gas unloading and deep evacuation system may more quickly, more efficiently and more completely unload liquefied gases from transport tanks, such as rail cars, into stationary storage tanks or into truck tanks. The system may utilize a two stage compressor, an electric motor, a variable frequency drive, a four way valve, a three way valve, a two way valve, a programmable logic controller based control system and pressure and temperature transmitters. The valving enables deep evacuation of the transport or supply tank to more completely empty the transport tank. The programmable logic controller and variable speed drive may be used to variably control the speed of the two stage compressor so that the system may be running as fast as possible during changes in ambient temperature and/or different stages of offloading the liquefied gases without exceeding the compressor's horsepower limit.
