HRS construction
Hydrogen Refueling Station Construction
A hydrogen refueling station(HRS) is a place to recharge hydrogen for hydrogen electric vehicles. HRS is a facility that can safely and quickly supply hydrogen, the clean energy of the future that replaces gasoline, diesel, and CNG, which are conventional automobile fuels.
Hydrogen Refueling Station Construction
Hydrogen refueling stations are classified into On-Site method and Off-Site method according to the hydrogen supply method and installed.
On-site HRS
-
On-site HRS is a method of producing hydrogen through a reformer and water electrolyzer within the site of a hydrogen Refueling Station, and has the disadvantage of high initial investment cost.
Off-site HRS
-
Off-site HRS is a method of transporting hydrogen produced from hydrogen production bases, etc. to HRS by pipeline or tube trailer, and has the disadvantage of incurring additional transportation costs due to hydrogen transport.
Hydrogen Refueling process
- Produce
-
Hydrogen production methods include hydrogen, which is incidentally generated from power plants, LNG reforming, and water electrolysis.
- Storage
-
In the case of Off-Site HRS, hydrogen is stored in the tube trailer.
- Compression
-
A large amount of hydrogen is compressed by a compressor.
- Recompression
-
Accumulation of pressure in a high-pressure storage container using a compressor
- Cooling
-
Since hydrogen compressed under high pressure is in a high temperature state, it is lowered to a constant temperature through a cooler.
- Refueling
-
Hydrogen is charged to FCEV through dispenser.
