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.

5. Full Customization Support

All pressure, flow, cooling mode and skid size can be modified to match limited plant space and special process requirements. We provide one-to-one engineering scheme design for non-standard working conditions.

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.

All mechanical assemblies are optimised for uninterrupted 24/7 steady-state operation with minimal pressure fluctuation, supporting full-cycle Industrial Green Hydrogen Solutions.
2. Ultra-High Discharge Pressure Coverage
Three standard industrial pressure grades cover mainstream hydrogen energy requirements: 32 MPa for medium-pressure storage, 90 MPa for 70 MPa hydrogen refuelling stations, and customisable 250 MPa variants for ultra-high-pressure storage and aerospace testing. The 90 MPa model delivers stable 87.5 MPa outlet pressure from a standard 12.5 MPa low-pressure hydrogen inlet, representing a landmark domestic technological breakthrough to replace imported compression hardware for Green Hydrogen Production Plant projects.
3. 100% Oil-Free & Zero Leakage Gas Circuit
The metal diaphragm physically isolates hydrogen process gas from the hydraulic drive circuit, eliminating all oil contamination risks critical for high-purity hydrogen applications including fuel cell refuelling, semiconductor manufacturing and CVD crystal growth. Full welded static sealing throughout the gas path achieves certified zero hydrogen fugitive emissions, meeting stringent hazardous gas safety standards for premium Renewable Hydrogen supply.

FAQ’S

What maximum discharge pressure and flow can your diaphragm compressors achieve?

Our standard product line delivers 32 MPa and 90 MPa fixed discharge pressure models with peak volumetric flow up to 2000 Nm³/h. Custom-engineered 250 MPa ultra-high-pressure variants are available on demand, with flow rates tailored to customer project specifications. The 90 MPa model reliably outputs 87.5 MPa hydrogen from a standard 12.5 MPa low-pressure inlet feed, suitable for all sizes of green hydrogen plant.

Does the diaphragm compressor require dedicated full-time operating staff?

Continuous manual supervision is not required. The entire skid operates under fully automated PLC control with remote fault alert notifications and automatic safety shutdown triggers for abnormal pressure, temperature or diaphragm failure conditions. Routine preventive maintenance can be completed by the client’s in-house technical personnel following the supplied operation manual.

Can we customise compressor pressure and flow capacity to match our exact hydrogen compression demand?

Yes. We offer three standard pressure grades alongside fully customised flow and discharge pressure engineering, with parallel multi-skid layouts designed to deliver total compression throughput tailored to unique customer hydrogen storage, refuelling or industrial process consumption profiles.

Why select diaphragm compression technology over piston compression for hydrogen service?

Diaphragm architecture delivers three irreplaceable advantages for hydrogen compared to Reciprocating Hydrogen Compressor piston compressors: complete oil-free operation to preserve hydrogen purity, absolute zero gas leakage for hazardous hydrogen safety, and suitability for ultra-high compression ratios to reach 90 MPa+ discharge pressures in a single compact skid. Lubricated piston compressors introduce oil contamination risks and higher fugitive emissions, making them unsuitable for high-purity hydrogen and refuelling applications. Our engineering team evaluates upfront capital expenditure and full lifecycle maintenance costs to guide clients to optimal compression technology selection for Industrial Decarbonization projects.

How complex is on-site installation of the diaphragm compressor skid?

All compressor units are fully integrated factory skids with pre-routed piping, pre-mounted instrumentation and pre-wired control panels. Standard single-skid site setup can be completed within 3–5 working days by our field engineering team. We provide full installation supervision, commissioning and operator maintenance training as part of the standard supply scope.

What noise levels does the diaphragm compressor produce during operation?

The balanced low-vibration hydraulic drive and acoustic-optimised cabinet design limit sound pressure levels below 75 dBA at a 1-metre distance, making the complete compressor package suitable for indoor industrial facility installation without mandatory dedicated acoustic enclosures.

What is the standard preventive maintenance schedule for the diaphragm compressor?

Full detailed maintenance timelines, diaphragm replacement cycles and component inspection checklists are documented within the official equipment Operation & Maintenance Manual. Routine minor inspections and filter changes are scheduled monthly, with core diaphragm assembly overhaul intervals spanning multiple years of continuous rated-load operation.
