Abstract
A high-pressure hydrogen filling system with expansion turbine having a simple configuration, requiring less maintenance and control duties, capable of being operated at low costs including electric power consumption cost, and allowing the use of general-purpose materials for composing the components of a hydrogen gas supply unit, a cold accumulator is installed at the outlet of an expansion turbine in a system performing hydrogen gas enthalpy drop when pressurizing and filling highly-pressurized and accumulated hydrogen gas into a tank.
Claims6
A high-pressure hydrogen filling system with an expansion turbine, and a cold accumulator comprising a pressure resistant vessel, the vessel containing and holding a cold accumulator element, is installed in a pipeline connected to an outlet of the expansion turbine in the hydrogen gas filling system for performing hydrogen gas enthalpy drop by using the expansion turbine.
