Hydrogen

Hydrogen Storage Alloy & Hydrogen Cylinder

Hydrogen in gaseous state reacts to special metal alloy called hydrogen storage alloy and then it is stored as metallic hydride. Metallic hydride storing hydrogen is mounted in the safe hydrogen storage cylinder with the optimal design for supply. The hydrogen storage range of pressure is 3bar ~ 70 bar and it is a very safe hydrogen storage method with no risk of explosion. Compared to a liquid or gas storage (pressure: 700bar) for the given volume, it can offer 1.6 to 2 times the hydrogen storage capacity.

Hydrogen Storage Alloy (Metal Hydrides)

Ti-Mn2 base alloy with durability proven by more than 10,000 times life cycles.

Max variable storage capacity : 1.8~1.9 wt% (differs depending on the pressure/temperature condition.)

Can adjust the equilibrium pressure (10 ~ 30 bar) depending on the requirements.

Can be applied to various areas. (Hydrogen ships, construction equipment such as forklift or excavator, unmanned underwater vehicle, hydrogen model city)

Can provide twice the hydrogen storage capacity compared to liquid storage, high pressure hydrogen storage method(High volume storage density). /Safe storage method. (No risk of explosion)

Comparison of Hydrogen Storage Capacities

*Assuming the cylinder volume of 1,000L

Storage method Storage capacity
Compressed gas at 64 barA 5.2Kg by H2(4.6%)
Compressed gas at 700 barA 57Kg by H2(50.4%)
Cryogenic Liquid 70.8Kg by H2(70.8%)
W-Alloy 113Kg by H2(100%)
