확장터빈·프레서형 고압수소가스충전 시스템은 구성과 현장공사비가 적고 정비작업 부담이 적어 확장설비에서 생산되는 에너지를 꺼내 발전기 등 외부에서 효과적으로 사용할 수 있는 방법을 별도로 제공할 필요가 없으며, 수소충전소 최종 충전 부분에 냉각기 기능 등 온도저하시스템 기술을 적용할 수 있고, 팽창터빈 부분은 팽창터빈을 이용해 수소가스의 엔트로피를 낮추는 공정이 있다.
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.
