Hydrogen Compressor
With over 30 years of expertise in hydrogen compression technology, MINNUO is a leading provider in the world. More than 2,000 of our units are successfully operating in various hydrogen applications, delivering a combined installed horsepower exceeding 2 million.
Types and Applications of Hydrogen Compressors
Hydrogen compressors are primarily classified into diaphragm-type and reciprocating (piston-type) compressors. They are widely utilized in industrial gases, food and pharmaceuticals, petrochemicals, aerospace, nuclear power, military equipment, and scientific research.
What is a Hydrogen Compressor?
A hydrogen compressor discharges hydrogen collected from water electrolyzers for storage and transport. Common applications include ship engineering, industrial processing, and hydrogen refueling stations. These compressors typically operate at pressures exceeding 15,000 psi to enable efficient storage. The most commonly used types are piston and metal diaphragm compressors, collectively known as reciprocating compressors.
Role of Hydrogen Compressor
Hydrogen compressors are essential for hydrogen storage and transportation. MINNUO offers various models to support the entire hydrogen energy chain, including:
- Hydrogen production from methanol, natural gas, and coal gas
- Hydrogen production by water electrolysis
- Hydrogen supply for hydrogen refueling stations
- Benzene hydrogenation
- Tar hydrogenation
- Catalytic cracking
- Other hydrogen boosting processes
Diaphragm Compressors
Diaphragm compressors are the core pressurization equipment for hydrogen refueling stations. The diaphragm fully isolates the cylinder from the oil chamber, ensuring exceptional sealing and maintaining hydrogen purity. Compression is achieved through reciprocating diaphragm motion during oil pressure fluctuations.
MINNUO Diaphragm Compressors
- Four main types: V, Z, D, L
- 26 series, nearly 900 models
- Maximum displacement: 3,000 Nm³/h
- Maximum pressure: 100 MPa
- Maximum piston force: 250 kN
- Maximum drive power: 450 kW
- High operational safety, minimal gas leakage risk
- Low procurement cost, compact design, and energy efficiency
Reciprocating Compressors
Piston-type hydrogen compressors function through a crankshaft-driven system, where connecting rods move the piston up and down to compress hydrogen. The piston rings act as seals, and lubrication ensures smooth operation.
MINNUO Reciprocating Compressors

- Maximum drive power: 4,500 kW
- PLC automatic control
- Multiple cooling options: air, water, mixed
- Various installation options: skid-mounted, fixed, soundproof cabin
Diaphragm Compressor Technology & Benefits
Key Advantages
A diaphragm compressor features a flexible membrane separating two chambers—one containing hydrogen and the other filled with a non-reactive gas like nitrogen. Increasing pressure in the nitrogen chamber compresses hydrogen in the adjacent chamber, enabling storage and transport at high pressures.
- Lubrication-free cylinder ensures no contamination, achieving 99.999% purity
- Ideal for compressing high-value rare gases, toxic, flammable, or radioactive gases
- Excellent heat dissipation and high-pressure capability with two-stage compression
- Close to isothermal compression, enhancing efficiency and safety
- Widely used in industrial gas, pharmaceuticals, petrochemicals, aviation, military, and research applications
