Hydrogen compressors are used to compress hydrogen fuel for storage. The units work by minimizing the volume of hydrogen gas thus producing pressure that produces liquid or compressed hydrogen. Hydrogen should be stored at substantial pressure (5,000-10,000 PSI) mainly because it has small density at atmospheric pressure.
Types of hydrogen compressors
There are numerous types of compressors within the market that you can choose. The widespread ones are:
Piston: Often known as metal diaphragm compressors, these units operate by trapping small quantities of hydrogen in an enclosed space. They then lower the gas's volume by displacement after which release the gas into the storage tank. The units work similar to this continuously until the tank receives total.
Guided rotor compressor: This type makes use of lobed rotor that is often mounted on an accentric shaft. In accordance to professionals, the unit functions inside the same principle as rotary interior combustion engines where it relies on the displacement of gas within the chamber.
Lower volume compressors: They are characterised by insufficient moving parts. They are of many types, nevertheless the most widespread are hydride compressors that produce small quantities of hydrogen that is used in laboratories. To produce this gasoline they utilize thermal reaction properties.
Electrochemical: These ones make use of membrane-electrode assemblies that are similar to those used in proton exchange membrane gasoline cells. They are unique in that they never have moving parts and yet they are able to reach substantial pressures of up to ten,000 psi dependent on their structure.
Linear: This can be a single piston unit that makes use of dynamic counterbalancing where the auxiliary mass is attached to a movable piston assembly. The unit is closely used in cryogenics.
Tutorial on buying the compressor
In your case to obtain the right compressor you need to take into account a number of components. One of the components to take into consideration is your needs. What does one need the compressor for? If you need it for dwelling use, you need one with a small horsepower. If on the other hand you need one for industrial purposes, you should select one with an increased horsepower.
Yet another factor to consider is the servicing that you need. Oil-free compressors have sealed bearings and infrequently require significantly less upkeep compared to their oil-lubricated counterparts. The oil-lubricated compressors require more upkeep when you must adjust the oil regularly. While this is definitely the case, you should note that the oil-free units tend to produce more power than the lubricated units.
