Different Types of Hydrogen Compressors

A hydrogen compressor, because the name suggests, is a kind of device that compresses hydrogen and turns it into liquid or compressed hydrogen. These devices decrease the volume of hydrogen to get the desired results.

Pumps vs Compressors

There just isn’t a great difference between a compressor as well as a pump. Both with the devices can improve the pressure on the liquid to move it by using a pipe. Since it is possible to compress gases, use this compressor to limit the hydrogen gas volume. On the other hand, a consistent pump improves the pressure to transferred liquid hydrogen to a different place.


Given here are a few types of Hydrogen Compressors.

Reciprocating Piston Units

These products are one from the most common units to compress hydrogen. Typically, they could be found in refineries where these are backbone of crude oil refinement. Usually, these units could be non-lubricated for oil-lubricated. For best results, you might want advanced familiarity with packing rings and piston sealing.

Ionic Liquid Piston Units

As the name suggests, these compressors provide ionic liquid piston instead of a metal piston. On the other hand, piston metal diaphragm compressors employ a different technology.

Electrochemical Units

This sort of compressor uses several membrane electrode assemblies just as the one obtained in proton-exchange membrane fuel cells. The good thing about these units is simply because feature no moving parts. Apart from this, they’re quite compact. As for as functionality can be involved, an electromechanical compressor just isn’t much distinct from a fuel cell. When current is passed throughout the membrane, hydrogen passes through it.

In these units, pressure requirement is 1000 bars or 14500 PSI. In 2011, a single-stage compression around 800 bars was recorded.

Hydride Units

In the truth of a hydride compressor, they choose pressure and thermal properties in the substance to be able to absorb hydrogen gas at room temperature. Afterward, high-pressure hydrogen is released at high temperatures available as gas. Typically, an electric coil and warm water is used to heat the bed of hydride.

Piston-Metal Diaphragm Units

These units are stationary and show high pressure. They are water-cooled and have absolutely four stages. Since compressing gases generates a great deal of heat, you have to know that the temperature on the compressed gas is reduced between different stages as a way to make the compression more isothermal. By default, the efficiency ratio is 70% in the event the process is complete.

Guided Rotor Units

This compressor is dependant on an involutes trochoid geometry that creates use of any parallel trochoid curve to be able to define principle compression volume. As far because the adiabatic efficiency is worried, the task can give you undoubtedly are a figure of 80 to 85%.

Linear Units

Linear compressors make usage of dynamic counterbalancing. In these units, an auxiliary mass is attached to a movable piston assembly plus a compressor. The beauty of these compressors is because have zero vibration while operating. Plus, they don’t utilize a lot of power.

Long story short, this was an breakdown of different forms of hydrogen compressors. This will help you choose the best unit to satisfy your needs.
