According to aspects, hydrogen fueling systems and methods are provided, including vehicle-to-vehicle communication techniques, hydrogen cooling techniques and/or hydrogen dispenser control techniques that facilitate improving aspects of a hydrogen fueling station. According to one aspect, an annular heat exchanger adapted to operate in a high-pressure and high-UA hydrogen fueling environment is provided.

Hydrogen fueling systems and methods

According to at least one aspect, a hydrogen gas dispensing system is provided. The hydrogen gas dispensing system includes a source configured to provide a hydrogen gas, a storage device configured to store the hydrogen gas up to a first pressure level, a dispenser configured to dispense the hydrogen gas up to a second pressure level that is higher than the first pressure level, and a compressor configured to compress the hydrogen gas from the source up to the first pressure level for storage in the storage device and configured to compress the hydrogen gas from the storage device up to the second pressure level for dispensing via the dispenser. According to at least one aspect, the dispensing system comprises an input power port configured to receive input power and an output power port configured to deliver output power derived from the input power to charge an electric vehicle.

Hydrogen gas dispensing systems and methods

According to aspects, hydrogen fueling systems and methods are provided, including vehicle-to-vehicle communication techniques, hydrogen cooling techniques and/or hydrogen dispenser control techniques that facilitate improving aspects of a hydrogen fueling station.

A hydrogen extraction system is provided. The extraction system can comprise a compressor for compressing a gas mixture comprising hydrogen and a desulfurization unit for receiving the compressed gas mixture. The system can also comprise a hydrogen-extraction device for receiving a reduced-sulfur gas mixture and a hydrogen storage device for receiving an extracted hydrogen gas. A method of extracting hydrogen from a gas mixture comprising natural gas and hydrogen, and a method of determining an energy price are also provided.

Distributed hydrogen extraction system

According to the present invention, a temperature profile within a preferential oxidation reactor is controlled using a two phase water/steam system to provide a temperature range within the reactor () which favors the selective oxidation of CO in a hydrogen rich reformate stream. The reformate is flowed in a mixture with oxygen over a preferential oxidation catalyst (). The temperature profile is controlled by flowing a stream of water proximate to the preferential oxidation catalyst () so as the stream of water and the reformate stream passing over the catalyst () are in a heat transfer arrangement. The stream of water is maintained as a two phase stream from a point at which the water reaches its boiling temperature to a point proximate an outlet from which the stream of water exits the reactor ().
