Title:

EXPANSION TURBINE FILLING SYSTEM FOR HIGH-PRESSURE HYDROGEN

Document Type and Number:

WIPO Patent Application WO/2018/012320

Kind Code:

A1

Abstract:

Provided is an expansion turbine filling system for high-pressure hydrogen, which has a simple configuration, which has low maintenance management work burden, which can lower operation cost including power consumption cost, and which can use a general-purpose member for a component member of a hydrogen gas supply unit. This filling system reduces the enthalpy of hydrogen gas by using an expansion turbine (11) when applying pressure and filling a tank (6) with hydrogen gas pressurized to a high pressure, wherein a regenerator (14) is provided to the exit of the expansion turbine (11).
