A method for communicating regarding supply of hydrogen of a moving vehicle to one or more distribution stations begins by collecting at least two parameters relating to the vehicle during its movement by two or more sensors onboard the vehicle. The parameters include at least the current location of the vehicle. Next, the parameters are transmitted to a control module. At least one parameter relating to hydrogen available in the one or more distribution stations is then collected by another sensor, which then transmits the hydron availability parameters to the control module. A hydrogen distribution station is then identified while the vehicle is moving, and a user of the vehicle is informed of available hydrogen distribution stations and of hydrogen supply conditions in the identified distribution stations.

A mobile vehicle servicing system includes a trailer having an elongated bed with peripheral vertical lip, four vertical stanchions disposed about the sides of the bed each of which support four corresponding carriages that are connected to a lift platform and are positionable by four actuators. The system further includes an oil supply and a used oil reservoir.

The invention relates to a system for transfer of a fluid product and its use, comprising at least one tubular arrangement for conveying the product between two locations and having two segments (2a, 2b) articulated to each other by a first of their ends, the opposite end of a first of the two segments being rotatably suspended from a support arm (1) adapted to be installed at one of the two locations and the opposite end of the second segment being able to be connected to a coupling means adapted to be installed at the second location, first means (13, 15) for turning the first segment (2a) relative to the arm, for the purpose of lowering its first end from a storage position on the same side as the support arm and second means (33,11) for pulling up the end of the second segment (2b) which end is adapted to be linked to the coupling means for the purpose of connecting that end to the coupling means (6) from underneath.

Methods and systems for reducing a pressure of compressed natural gas and for delivering natural gas are disclosed. A regulator comprising a vortex tube may be used to reduce the pressure of compressed natural gas while a temperature thereof is also reduced. The temperature reduction associated with a pressure drop in the compressed natural gas is achieved by throttling the gas at constant enthalpy from 3,000 psig to 150 psig through the regulator. At least one heat exchanger may be utilized to increase the temperature of the compressed natural gas to a temperature suitable for injection delivery. A pressure-reducing regulator may be used to further reduce a pressure of the gas to about 45 psig for delivery to an end-user.
