An attachment for a hydrogen refueling port of a vehicle, the port designed according to the known SAE J2799 international vehicle standard. The attachment is designed to be incompatible with the supply of hydrogen to said vehicle. The attachment includes a nozzle for being connectable to the refueling port and a protruding handle, and at least one of the following features: i) a magnetic element; and ii) a locking device for reversibly locking onto a portion of the refueling port.

A multi-stage gas compression, storage and distribution system utilizing a hydrocarbon gas from a municipal gaseous supply line in a manner that does not affect an operational integrity of said municipal gaseous supply line includes an inlet line fluidly in fluid communication with a supply of hydrocarbon gas at a first pressure, a first compression unit configured to compress the hydrocarbon gas from the inlet line to a second pressure, a first storage vessel configured to receive the hydrocarbon gas from the first compression unit for storage at the second pressure, a second compression unit configured to compress the hydrocarbon gas from the first storage vessel to a third pressure, and a second storage vessel configured to receive the hydrocarbon gas from the second compression unit for storage at the third pressure.

A heat exchange system includes a cold source, a heat dissipation apparatus, a water storage tank, a heating portion, and a cooling portion. The heating portion is coupled between the cold source and the water storage tank. The cooling portion is coupled between the heat dissipation apparatus and the water storage tank. The cooling portion transmits heat of the heat dissipation apparatus to water of the water storage tank to cool the heating portion, and the heating portion transmits heat of the water of the water storage tank to the cold source to heat the cold source.

Systems and methods for controlling the temperature and pressure of a cryogenic liquid methane storage unit are provided. The disclosed systems and methods generate methane gas from a reservoir of liquid methane stored within the methane storage unit, vent the methane gas through one or more outlet valves connected to the methane storage unit, and generate electric power using the vented methane gas. The generated electric power can then be used to initiating a cooling cycle, which reduces the temperature of said reservoir of liquid methane and reduces the pressure in said methane storage unit. Micro anaerobic digesters and methane storage units may be configured in a networked environment with a central controller that monitors remote units.

The invention relates to a device for providing pressurized fluid. The device includes a first functional assembly including a pressurized fluid bottle having an opening having attached therein a first tap including an inner fluid circuit including an insulating valve. The device includes a second functional assembly forming a physical entity separate from the first assembly. The second assembly includes a second tap having an inner fluid circuit. The first tap and the second tap include respective coupling members forming a removable rapid connection system. The device includes in the first assembly at least one electronic data storage communication unit that is removably, wirelessly queryable via electromagnetic waves and in that the second assembly includes at least one electronic communication unit for removably, wirelessly reading, via electromagnetic waves, data from the electronic member of the first assembly.

A method of transferring a liquefied gas under pressure contained in a container into a tank or a gas transport network. The container is connected to a recirculation circuit that includes a heater and a recirculation pump connected in series with the heater, upstream from the heater, and arranged to discharge liquefied gas taken from the bottom of the container into the heater, the method including connecting the container to the tank or to the network, via a circuit for transferring the liquefied gas in the liquid phase and not having a pump; allowing the liquefied gas to be transferred to the tank or to the network via the transfer circuit under the effect of a higher pressure in the container; and operating the pump to compensate for the reduction in pressure inside the container during transfer.

An apparatus for remote inspection of fire extinguishers at one or a system of fire extinguisher stations includes, e.g., at each fire extinguisher station: a detector for lack of presence of a fire extinguisher in its installed position at the fire extinguisher station; a detector for out-of-range pressure of contents of the fire extinguisher at the fire extinguisher station; a detector for an obstruction to viewing of or access to the fire extinguisher at the fire extinguisher station; and a device for transmission of inspection report information from the fire extinguisher station to a remote central station.

A device that can be attached to the outlet of a gas cylinder, which can monitor and display in digital or analog form the pressure of the gas in the cylinder and the interval of time remaining until the amount of gas in the cylinder will reach a predetermined lower threshold at a given flow.
