Onsite Ultra-High Pressure Hydrogen Compression

Onsite compression of high-purity hydrogen to ultra-high pressure grades (32 MPa, 90 MPa, 250 MPa) is achievable with our industrial Hydrogen Compressor diaphragm portfolio. The selection of compression model is determined by core evaluation criteria including target discharge pressure, required volumetric flow rate, inlet hydrogen pressure, footprint limits, capital expenditure and long-term operational cost.

At HYVODA, we specialise in domestic breakthrough diaphragm compression systems that fully substitute imported high-pressure hydrogen compression equipment, delivering turnkey skid packages for hydrogen refuelling stations, electrolysis integration and heavy industrial hydrogen production plant projects. As a professional Renewable Energy EPC Contractor, our engineering team delivers customised sizing and technical guidance to match your exact hydrogen compression duty cycle.

Diaphragm Compression Technology for Hydrogen

We are a leading domestic manufacturer of high-pressure hydrogen diaphragm compressors, with a growing global installed reference base covering Asian hydrogen refueling system hubs, petrochemical plants and renewable hydrogen plant facilities. Our equipment adopts all-metal sealed diaphragm compression architecture, delivering 100% oil-free, zero-leakage hydrogen compression without contaminating feed gas purity.

This is the safest, most reliable compression technology for high-purity hydrogen streams, requiring only grid power and process cooling water as site utilities, fully compatible with upstream methanol reforming hydrogen generation plants and electrolysis systems including Alkaline Electrolyzer and PEM Electrolyzer units.

Diaphragm Compression – Oil-Free Ultra-High Pressure Technology

Our three-tier diaphragm compressor platform supports volumetric flow rates up to 2000 Nm³/h per standalone skid unit. For super-scale hydrogen compression demand, multiple compressor skids can be paralleled with shared cooling, control and safety subsystems for modular capacity expansion, perfectly matching large-scale green hydrogen plant and hydrogen power plant operation demands.

Metal Diaphragm Oil-Isolated Compression Principle

Our compressor utilises a precision multi-layer metal diaphragm core design. Hydraulic oil drives reciprocating deflection of the diaphragm sheet, creating volumetric change within the fully isolated hydrogen gas chamber. Hydrogen is drawn into the gas cavity via suction valves during the diaphragm retraction stroke, then compressed and discharged through outlet valves as hydraulic pressure pushes the diaphragm forward.

The complete physical separation between hydraulic oil and hydrogen gas eliminates cross-contamination entirely. Full static sealing across all gas wetted components delivers near-zero atmospheric hydrogen leakage, while the differential pressure diaphragm architecture delivers intrinsically safe, low-complexity round-the-clock operation for Renewable Hydrogen production projects.

FAQ’S

Why diaphragm hydrogen compressor is more suitable for hydrogen fueling system than reciprocating piston compressor?

This Diaphragm Hydrogen Compressor adopts full metal diaphragm isolation structure, which completely separates hydraulic oil from hydrogen medium and achieves 100% oil-free compression, avoiding trace oil pollution that would damage fuel cell stacks of hydrogen fueling system. In contrast, Reciprocating Hydrogen Compressor inevitably carries tiny lubricant residues and has higher hydrogen leakage risks due to piston ring wear. Besides, the diaphragm unit supports ultra-high compression ratio to directly reach 87.5MPa outlet matching 70MPa vehicle refueling standards, with fully welded static sealing to lower hydrogen escape hazards, meeting strict safety and purity standards of hydrogen fueling system all year round.

What maximum customizable discharge pressure can this diaphragm unit reach for vehicle hydrogen refueling?

For standard vehicle hydrogen refueling scenarios, the Diaphragm Hydrogen Compressor can be customized to three mainstream pressure grades: 32MPa, 90MPa and 250MPa. The 90MPa model stably outputs 87.5MPa hydrogen with 12.5MPa inlet pressure, perfectly matching 70MPa hydrogen fueling system for passenger cars and commercial vehicles; the 250MPa customized version is applicable to ultra-high-pressure hydrogen storage and special fuel cell vehicle testing stations.

Can oil-free gas circuit perfectly cooperate with CPH ultra-pure hydrogen gas generator?

Absolutely. The full oil-free gas circuit of this Diaphragm Hydrogen Compressor has no contact between lubricating medium and hydrogen, and its pipeline interface parameters fully match the outlet specifications of CPH ultra-pure hydrogen gas generator. After PSA and metal membrane polishing by CPH, high-purity hydrogen will not be contaminated during subsequent compression, retaining 9N ultra-clean gas quality for hydrogen fueling system and semiconductor supporting facilities.

What anti-leakage design ensures safety for long-term green hydrogen plant operation?

The Diaphragm Hydrogen Compressor adopts double-layer metal clamped diaphragm structure plus full all-welded gas pipeline without detachable dynamic sealing points, realizing measurable zero hydrogen leakage. All gas-contact parts use hydrogen embrittlement resistant alloy materials, equipped with real-time hydrogen concentration sensors and automatic emergency shutdown interlocks. The closed gas circulation design eliminates fugitive hydrogen emission risks during long continuous operation of green hydrogen plant.

Is multi-stage compression configurable to lower single unit pressure load?

Multi-stage compression framework is optional for this Diaphragm Hydrogen Compressor. Customers can customize 3-stage standard layout or adjusted stage quantity according to inlet pressure and target discharge pressure. Step-by-step pressure reduction lowers single-stage compression temperature and load, reducing diaphragm fatigue loss and extending service life, suitable for large-scale hydrogen fueling system and hydrogen production plant with continuous high-throughput demand.

What’s the service life difference of core diaphragm compared with piston wearing parts?

The core metal diaphragm of Diaphragm Hydrogen Compressor has a service cycle of 3–5 years under rated continuous working conditions, with only regular visual inspection required. While Reciprocating Hydrogen Compressor’s piston rings, packing and valve components are vulnerable consumables that need monthly inspection and overhaul every 1–2 years. Diaphragm units feature fewer wearing parts and longer maintenance intervals, cutting long-term spare parts and labor costs for hydrogen fueling system operation.
