Two-tier tube-trailer operation method and system to reduce hydrogen refueling cost
A method and system are provided for operating refueling station tube-trailers and compressors to reduce hydrogen refueling cost. A hydrogen refueling station includes a two-tier fuel supply of pressure vessels on a refueling station tube-trailer, with a first tier and a second tier of pressure vessels including at least one or more pressure vessels connected together. A separate control unit is coupled to the first tier and the second tier of pressure vessels with each of the control units coupled to a compressor. The compressor is coupled to a high pressure buffer storage by a separate control unit. In operation, pressure is monitored in the each tier. Hydrogen is consolidated selectively between the first tier of pressure vessel banks, the second tier pressure vessels, and the high pressure buffer. Based upon monitored pressures, one of the first tier of pressure vessels, the second tier pressure vessel banks, and the high pressure buffer is used to refuel vehicles.
