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 high-pressure compressor having a hydraulic system and a gas chamber, where the hydraulic system includes a reservoir, connected to a hydraulic fluid chamber by a hydraulic flow path and a pump assembly positioned in the hydraulic flow path, and the compressor furthermore includes a control element controlling the flow of hydraulic fluid in the hydraulic flow path and thereby the pressure in the hydraulic fluid chamber, where the control element and the pump assembly is configured for controlling the pressure of hydraulic fluid in the hydraulic fluid chamber when the compressor is not in operation.

A system and method is provided for transferring liquid argon from a bulk storage tank to a transport tank in which liquid argon is pumped through a tube arrangement within a heat exchanger and the tube arrangement is contacted by liquid nitrogen so that heat transfers from the liquid argon to the liquid nitrogen, thereby reducing the temperature, density and pressure of the liquid nitrogen prior to exiting the heat exchanger and flowing into the transport tank.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

In one example, a portable fuel gas system includes: a portable enclosure; a fuel gas supply manifold; a throttle in fluid communication with the fuel gas supply manifold. The fuel gas supply manifold includes a first pressure zone and a second pressure zone separated from one another by the throttle; and a fuel gas shutoff valve in fluid communication with the fuel gas supply manifold and operative to control a flow of a fuel gas in the fuel gas supply manifold, wherein the fuel gas supply manifold, the throttle, and the fuel gas shutoff valve are disposed within the portable enclosure.

In a gas supply system of one embodiment, if first detection information of a high-pressure sensor exceeds a first threshold value, a gas control ECU causes a pressure adjustment range to overlap a second error range of second detection information of a mid-pressure sensor, the second error range being defined with a second threshold value as a reference point. If the first detection information is less than or equal to the first threshold value, the gas control ECU offsets the pressure adjustment range relative to the second error range defined with the second threshold value as the reference point.

A pressure vessel system has a pressure vessel for storing gaseous fuel, a fuel line, and a total-pressure sensor for measuring a total pressure of the fuel at a position within the fuel line. This makes it possible for various functions, such as the control of power reduction, for example, to be performed more accurately than if only static pressure were being used. The technology disclosed here also relates to an energy supply arrangement having such a pressure vessel system and having an energy converter, such as a fuel cell, for example.
