Compressors for Hydrogen Refuelling Stations
The final boost that decides a station's dispensing capacity — 350/700-bar duty, zero leakage tolerated
Typical station duty: pipeline or trailer supply at ~20–30 bar(a), boosted to 450 bar(a) (350-bar dispensing) or 900 bar(a) (700-bar dispensing), in start–stop cycles that follow vehicle arrivals.
A typical duty profile
| Gas | Hydrogen (H2) |
|---|---|
| Capacity | 800 Nm³/h |
| Suction pressure | 30 bar(a) |
| Discharge pressure | 450 bar(a) |
| Suction temperature | 20 °C |
| Oil-free required | Yes |
| ATEX / hazardous area | Yes |
| Contamination | none |
| Duty | intermittent |
What the tool says on this profile
The tool's answer on this profile: Diaphragm Compressor (hydraulically actuated). Duty as derived by the engine: 800 Nm³/h, 30.0 bar(a) → 450.0 bar(a), overall pressure ratio 15.0.
Computed at build time by the same engine the tool runs — this page and the selector cannot disagree. Your duty differs from the profile? Run your own numbers below.
What to watch
- Hydrogen embrittlement rules the materials file — the alloy list is an engineering conversation, not a catalogue checkbox.
- Oil-free is non-negotiable: fuel-cell vehicles are poisoned by oil carryover at ppm levels.
- Above roughly 1,000 Nm³/h per train the diaphragm envelope ends — large stations split duty across parallel trains or look at the liquid-driven piston family.
