Establishment of Optimal Hydrogen Supply System such as Piping and Liquefied Transport

Currently, hydrogen is supplied through a tube trailer or pipe, but the tube trailer method has low transportation efficiency due to the small amount transported at once.
KOGAS aims to supplement this shortcoming, and to increase price competitiveness by connecting the charging stations near strategic extraction bases with pipes, and by transporting hydrogen after liquefying it using LNG cold heat to charging stations that are difficult to connect by pipelines.

Hydrogen Supply System Establishment Plan

Charging Stations near strategic production bases are supplied by installing piping,and areas where piping supply is difficult, LNG cold heat is used for liquefaction and supply of hydrogen.

You can check the Plan, Others, and Target for the Pipe supply and Liquid supply.
Classification	Pipe supply	Liquid supply
Plan	Local supply between strategic production bases and charging stations	Long-distance supply after liquefaction using cold heat at the receiving base
Others	Hydrogen piping for short-distance supply	Early start of liquid transportation to prepare for increase in demand, and to reduce supply cost
Target	Establishing 142km of pipelines, and four liquefied hydrogen bases by 2030

Pipe Supply vs. Liquid Supply

Move left and right

You can check the Definition, Advantages, and Disadvantages for the Pipe supply and Liquid supply.
Classification	Pipe supply	Liquid supply
Definition	Supplying hydrogen in large quantities by connecting production facilities and consumers with pipes	Supplying liquid hydrogen by tankers to overcome the low transport efficiency of tube trailers
Advantages	It is possible to supply in large quantities, and it minimizes site and civil complaints by supplying underground. It is cheapest when there is high demand, and it can be stored if it it is high pressure.	High transportation efficiency (3 to 10 times that of tube trailers per shipment) with range of flexibility
Disadvantages	It needs high initial investment, and it takes a long time to establish infrastructure.	High manufacturing cost, and low efficiency due to Boil-Off-Gas(BOG) generation in case of low demand
