China's Leading Hydrogen Liquefier Factory: 0.3TPD to 5TPD - Top Suppliers in Cryogenic Solutions
Product Description
Economy
Liquid hydrogen is about 800 times denser than gaseous hydrogen. Under the same hydrogen storage volume, liquid hydrogen can greatly improve the hydrogen storage capacity. The hydrogen storage density of liquid hydrogen can reach 14%, which is the highest hydrogen storage density at present. The use of liquid hydrogen technology can greatly reduce the cost of hydrogen storage, transportation and operation.
High Efficiency
In the process of hydrogen liquefaction, harmful impurities are solidified, and when used again in vaporization, the purity level of hydrogen can reach 6-7N, which can effectively improve the power and life of hydrogen fuel cells.
Security
The working pressure of liquid hydrogen storage and transportation is 1-1.3bar, which is safer than compressed gas hydrogen.
Major Applications:
- Energy Storage and Transportation: Liquid hydrogen serves as a medium for clean energy storage, facilitating long-distance transport and storage.
- Industrial Applications: Used in hydrogen fuel cells, rocket fuel, and other high-energy-demand applications.
- Research Purposes: Employed in low-temperature physics research and experiments.

Frequently Asked Questions
What is a Hydrogen Liquefaction Unit?
A Hydrogen Liquefaction Unit is a sophisticated system designed to cool gaseous hydrogen to cryogenic temperatures (around 20K), converting it into its liquid form for highly efficient storage and transportation.
Why is liquid hydrogen more economical than gaseous hydrogen?
Liquid hydrogen is approximately 800 times denser than gaseous hydrogen. This high storage density (up to 14%) allows for significantly larger storage capacities within the same volume, drastically reducing the costs associated with storage, transport, and overall operation.
How does liquefaction improve the purity and performance of hydrogen?
During the cooling process, harmful impurities within the hydrogen are solidified and removed. When the liquid hydrogen is vaporized for use, it achieves a purity level of 6-7N (> 99.9999%), which helps maximize the power output and lifespan of hydrogen fuel cells.
Is liquid hydrogen storage safer than compressed gas?
Yes. Liquid hydrogen storage and transportation operate at a low working pressure of 1-1.3 bar, which is significantly lower and safer than the extremely high pressures required for compressed hydrogen gas.
What are the main applications for these liquefaction units?
These units are primarily used for large-scale clean energy storage and long-distance transport, industrial applications including rocket fuel and hydrogen fuel cells, as well as scientific research in low-temperature physics.
What is the power consumption and para hydrogen content of the FHH series?
The FHH series features a power consumption of 15~20 kw.h/kg LH2, maintaining a para hydrogen content of over 95% and an outlet temperature of 20K.
