Hydrogen Liquefaction

« Back to Glossary Index« Back to Previous Page

Definition:
The process of cooling hydrogen gas to cryogenic temperatures (-253°C) to convert it into a liquid for high-density storage and transport.

Key Components:

  • Cooling Systems: Reduces hydrogen temperature to near absolute zero.
  • Insulated Storage Tanks: Maintains liquid hydrogen in a stable state.
  • Heat Exchangers: Facilitates energy-efficient liquefaction.

Use Cases/Industries:

  • Long-Distance Hydrogen Transport: Used for shipping hydrogen internationally.
  • Aerospace Applications: Hydrogen is a primary fuel for space launch vehicles.
  • Hydrogen-Powered Mobility: Enables high-energy storage for hydrogen-fueled aviation and marine transport.

Advantages:

  • High Storage Density: Allows large quantities of hydrogen to be stored in small volumes.
  • Long-Term Storage Viability: Reduces hydrogen loss compared to gaseous storage.

Challenges:

  • Energy-Intensive Process: Hydrogen liquefaction consumes about 30% of its energy content.
  • Boil-Off Losses: Some hydrogen evaporates during storage and transport.

Related Terms:
Cryogenic Hydrogen, Liquid Hydrogen Tankers, Hydrogen Economy

Example:
Japan developed the world’s first liquefied hydrogen carrier, Suiso Frontier, to transport liquid hydrogen from Australia.
