Embodiment 1

[0119] A city plans to build a hydrogen refueling station, but there is no hydrogen source nearby for purchase, and there are urban natural gas pipelines near the hydrogen refueling station. The hydrogen filling pressure levels in the hydrogen refueling station are 35 and 70MPa, and the hydrogen filling time is concentrated. The main service objects are: 30 taxis (hydrogen filling pressure level is 70MPa), 20 buses (hydrogen filling pressure level is 35MPa ), 15 passenger vehicles (hydrogen filling pressure level is 35MPa), and other vehicles (hydrogen filling pressure level is 35MPa) use 200kg of hydrogen (unit: kg), which is highly sensitive to shutdown.

Embodiment approach

[0120] According to the above planning conditions, the implementation method of equipment selection for hydrogen refueling station for natural gas reforming and hydrogen supply is as follows:

[0121] 1. Determine the following basic parameters

[0122] (1) Daily hydrogen supply volume of natural gas reforming hydrogen supply station m=5×30+20×20+15×15+200=975kg

[0123] (2) The hydrogen filling time of the natural gas reforming hydrogen supply and refueling station is concentrated, T=10h;

[0124] (3) Hydrogen addition per hour m T =975kg / 10h=97.5kg / h

[0125] (4) Since the main service object of the natural gas reforming hydrogen supply and hydrogen refueling station is the bus, the shutdown sensitivity is relatively high;

[0126] (5) The hydrogen filling pressure grade P is 35MPa and 70MPa.

[0127] 2. Selection of natural gas reforming system: determine the number n of natural gas reforming equipment

[0128] The total amount of natural gas processed by the natural g...

Description

technical field [0001] The invention relates to the technical field of hydrogen energy, in particular to a method for selecting equipment of a natural gas reforming hydrogen supply station. Background technique [0002] Hydrogen energy is a typical energy storage carrier and a secondary energy source. It is also an efficient and clean medium connecting primary energy such as coal, oil, natural gas, wind energy, and water energy with electric energy. Due to the high efficiency of hydrogen energy utilization and no pollution-free emissions after use, fuel cell vehicles powered by hydrogen are an inevitable choice for the replacement of traditional fuel vehicles. A hydrogen refueling station is an energy supply service facility that supports the large-scale application of fuel cell vehicles. It can realize various processes such as hydrogen energy production, storage, boosting, and filling. [0003] Hydrogen production by reforming natural gas is a commonly used hydrogen produ...
