Hydrogen is widely used across many industries.
It is a highly versatile and valuable gas with a wide range of applications.
On this page, I will outline available compressor solutions depending on your application, required gas purity, compressor type (piston or diaphragm), and other key factors.
Let’s get started.
Part #1 – compressor type
When selecting a hydrogen compressor, the first step is to determine which type of compressor you need.
In general, there are two main options:
- Oil-lubricated piston compressors for hydrogen (H₂)
- Oil-free compressors for hydrogen (H₂)
Which one is better?
There is no correct answer.
The choice depends primarily on the required gas purity — whether it is 90–95% H₂ or ultra-high purity levels such as 99.999%–99.9995% H₂.
Oil-lubricated hydrogen compressors combined with a purification system are typically recommended for applications where ultra-high purity is not required.
Here is one example with ⚙️ technical parameters:
• Gas: Hydrogen (H₂), 99%
• Discharge pressure: 200 barg (~2900 psi)
• Capacity: 100 Nm³/h (60 cfm)
• Cooling: Water-cooled
• Motor: 55 kW, direct drive
• Scope of supply: Standard, without additional filtration systems
• Control panel: Included
Another example — if you require high-purity gas, a diaphragm compressor for hydrogen (H₂) should be used.
It is an oil-free, zero-leakage compressor that ensures maximum gas purity.
🚀 H₂ Compressor for Hydrogen Refueling Stations and Other Applications – it’s our 2 stages oil-free and most popular diaphragm compressor.
- Capacity: 5 Nm³/h
- Inlet pressure: 5 barg
- Outlet pressure: 400 barg
- Motor power: 5.5 kW
- Cooling: Water-cooled
- Design: Absolutely oil-free
- Configuration: 2-stage diaphragm compressor (2 cylinders)
or 100 Nm3/h compressor:
Part 2 — Technical Parameters
Depending on the application, there are hundreds of different compressor models and configurations available.
However, the first step is to clearly define the key parameters:
- Inlet gas pressure
- Outlet gas pressure
- Capacity
I strongly recommend reading my article:
“The Three Main Parameters for Compressor Selection Everyone Must Know Before Purchasing”
I would also like to draw your attention to the fact that, depending on the combination of inlet and outlet pressures as well as capacity, different compressor types are typically used:
- Low pressure (5–10 barg) and low capacity (5–30 Nm³/h) — oil-free reciprocating or diaphragm compressors
- Low pressure (5–30 barg) and high capacity (200–1000 Nm³/h) — oil-free or oil-lubricated reciprocating compressors
- High pressure (50–1000 barg) and low capacity (10–100 Nm³/h) — diaphragm compressors
- High pressure (50–1000 barg) and high capacity (200–1000 Nm³/h) — mainly reciprocating compressors
Part 3 — What Compressors Are Available?
We offer hundreds and even thousands of compressor configurations tailored to different applications.
However, I strongly recommend not selecting a hydrogen compressor solely based on the tables below.
Instead, please send us a request for a quote via the contact form on the Contact page.
That said, the examples below will give you an overview of the wide range of options we can provide. We offer a large variety of solutions.
