Exergy Analysis of Filling Process of Liquid Hydrogen Fueling Station

As a clean and pollution-free efficient green energy, hydrogen energy is gradually replacing fossil fuels and becoming an important member of the development and transformation of energy structure. Compared with gas hydrogen, liquid hydrogen has high mass density and high volumetric density, which is an ideal storage and transportation mode. Liquid hydrogen refueling station is an important link in the hydrogen energy industry chain, and is an important infrastructure connecting the supply side and the demand side. However, there are few researches on liquid hydrogen refueling stations in China. At present, only one liquid hydrogen refueling station has been built in Pinghu. Exergy destruction caused by each component of the hydrogen refueling station in the refueling process can be evaluated for energy loss caused by the whole refueling process and guide the future optimization design direction of the hydrogen refueling station and its important components.
