An expansion turbine/compressor type high-pressure hydrogen gas filling system is simple in configuration, low in site work cost, small in the burden of maintenance work, and capable of reducing the operating cost including cost of power consumption, and it is not necessary to separately provide a way to take out the energy produced in the expansion equipment and effectively use outside such as generator, and that can be applied for temperature lowering system technology such as pre-cooler function in the final filling portion of the hydrogen station, the expansion turbine portion has with a process to incorporate the expansion turbine/compressor in the expansion turbine portion in the filling system to do the enthalpy lowering of the hydrogen gas using the expansion turbine, when the hydrogen gas accumulated at high pressure is pressurized and filled into the tank. |
