Abstract: Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.

Abstract: A system and method for transporting and distributing hydrogen, reducing the risk of hydrogen leakage, maintaining a record of provenance, and measuring and recording its purity level as it flows from source to destination to assure it complies with a predetermined range of values. The system includes a hydrogen delivery line made from metallic or non-metallic pipe that may be placed inside a safety pipe such that a channel is formed between an exterior of the hydrogen delivery line and an interior of the safety pipe. A sweeper gas or liquid may be injected into the channel to purge any hydrogen that might escape from the hydrogen delivery line, and one or more sensors may be used to detect and avoid the presence of an unacceptable level of hydrogen, or to stop the flow of hydrogen and remediate the problem well before a safety or environmental risk can occur.

Abstract: A valve for closing a gas container includes a valve body with a continuous longitudinal bore along a longitudinal axis and a displaceably-guided valve tappet mounted therein. The valve body extends longitudinally parallel to the axis from a connection region with a connection-side end face to a fastening region with a gas-container-side end face having a smaller diameter than the connection region. The connection region has a stop face that stops a gas container base-body head when the fastening region has been inserted into an opening in the head. The valve body laterally has a double groove in the fastening region that includes two grooves that follow one another longitudinally and that a sealing lug facing away from the longitudinal axis separates to allow the head to be pressed gas-tightly with the fastening region in the double groove region when the fastening region is introduced into the head.

Abstract: Method and apparatus for blending first and second fuels for use by a combustion mechanism, such as a motor vehicle. The first and second fuels are stored in storage vessels of a fuel storage pod in a fuel storage ratio of total respective volumes established by a storage controller circuit of a storage module responsive to a predicted demand level. A blended fuel ratio is selected by a blend controller circuit of a blend module in response to an imminent demand parameter of a selected combustion mechanism, with the blended fuel ratio being different from the fuel storage ratio. A blend of the first and second fuels is thereafter dispensed to the selected combustion mechanism at the blended fuel ratio. The first fuel may be hydrogen (H2), and the second fuel may be a selected hydrocarbon, such as propane, butane, methane, hexane, gasoline or diesel.

Abstract: The invention relates to a nozzle, which has a main valve arranged in a channel, a coupling device (30) for producing a connection between the nozzle and the connecting piece (15), and an actuating apparatus (17) for actuating the coupling device and the main valve. The actuating apparatus comprises a manual lever (11), which is movable between a closed position and an open position. The actuating apparatus is designed to convert a movement of the manual lever in a region between the closed position and the open position to a temporally offset actuation of the coupling device and of the main valve. A coupling joint (20) connected to the manual lever is connected via operative connections to the coupling device having the main valve. The operative connections for the coupling joint form a guide such that the coupling joint is caused to rotate about a first pivot axis (41) and/or to move in a first direction when the manual lever is activated in a first manual lever region, and that the coupling joint having the manual lever in a second manual lever region is caused to rotate about a second pivot axis (42) and/or to move in a second direction.
