Shuntian designs and supplies hydrogen production equipment for industrial green hydrogen, on-site hydrogen generation and renewable-energy conversion projects.
Our hydrogen production systems can integrate the electrolyzer stack, power conversion equipment, water treatment, electrolyte circulation, gas-liquid separation, hydrogen purification, drying, cooling, instrumentation and automatic control into one coordinated plant.
Available solutions include alkaline water electrolysis equipment, PEM electrolyzer systems, modular hydrogen generators and containerized hydrogen production plants. Equipment configuration can be customized according to hydrogen output, purity, delivery pressure, power source, operating profile, site conditions and downstream application.
We support project developers, engineering companies, energy companies, chemical plants, industrial gas suppliers, research institutions and equipment distributors from initial technical evaluation through equipment manufacturing, testing, installation guidance and commissioning support.

Alkaline water electrolysis equipment uses an alkaline electrolyte and an electrical power supply to produce hydrogen and oxygen from treated water.
A complete alkaline hydrogen production system may include:
Electrolyzer stack
Rectifier and transformer
Electrolyte circulation system
Gas-liquid separators
Hydrogen and oxygen processing units
Water replenishment equipment
Cooling system
Hydrogen purification unit
Gas analysis instruments
PLC control cabinet
Safety interlocks
Ventilation and gas-detection equipment
Alkaline electrolyzers are commonly considered for industrial projects requiring continuous operation, modular expansion and medium- to large-scale hydrogen output.
The final equipment arrangement should be selected according to operating pressure, plant capacity, power conditions, dynamic-load requirements and project economics.
PEM water electrolysis systems use a solid polymer membrane and purified water to generate hydrogen.
PEM electrolyzers are often considered for projects that require:
Compact equipment layout
Rapid load adjustment
Frequent start and stop
Operation with variable renewable electricity
High-purity hydrogen production
Pressurized hydrogen output
Modular expansion
Limited installation space
A PEM hydrogen production package may contain the electrolyzer stack, deionized-water circulation, power conversion, cooling, gas separation, purification, process control and safety systems.
PEM technology should be evaluated according to project capacity, power profile, hydrogen quality, water quality, operating pressure and total lifecycle requirements.
A complete water-electrolysis hydrogen plant involves more than the electrolyzer stack.
| System Section | Main Function |
|---|---|
| Water treatment | Supplies water with the quality required by the electrolyzer |
| Power conversion | Converts incoming electrical power into controlled DC power |
| Electrolyzer stack | Splits water into hydrogen and oxygen |
| Electrolyte or water circulation | Maintains stable process flow and operating conditions |
| Gas-liquid separation | Separates generated gas from process liquid |
| Cooling system | Removes process heat |
| Hydrogen purification | Reduces moisture, oxygen and other impurities |
| Hydrogen drying | Achieves the required outlet dew point |
| Gas analysis | Monitors hydrogen purity and oxygen content |
| Compression | Raises hydrogen to the required delivery pressure |
| Storage | Balances production and downstream consumption |
| PLC control | Coordinates operation, alarms and safety interlocks |
| Ventilation and detection | Supports safe handling of potential hydrogen releases |
| Remote monitoring | Provides operating data, alarm records and system status |
The scope of supply should be defined clearly during the quotation stage. Buyers should confirm whether the proposal includes only the electrolyzer stack, an electrolyzer package, complete balance-of-plant equipment or a turnkey hydrogen production plant.
Water electrolysis uses electricity to separate water into hydrogen and oxygen.
A simplified production sequence is:
Feed water enters the water-treatment system.
Treated water is supplied to the electrolyzer process.
The power-conversion system provides controlled DC electricity.
Hydrogen and oxygen are generated in the electrolyzer stack.
Gas and process liquid enter the separation system.
Hydrogen is cooled, separated and purified.
The hydrogen is dried to the required specification.
Gas quality is checked by online instruments.
Hydrogen is supplied directly to the user or sent to compression and storage.
The PLC system monitors pressure, temperature, flow, purity and safety conditions.
The actual configuration varies between alkaline and PEM electrolysis systems and between different plant capacities.
Hydrogen produced from renewable electricity can be supplied to an ammonia synthesis process.
The hydrogen plant must be coordinated with:
Ammonia plant capacity
Required hydrogen pressure
Nitrogen production
Continuous operating demand
Hydrogen buffer storage
Renewable-power availability
Hydrogen can react with captured carbon dioxide in synthetic methanol and other Power-to-X processes.
Stable hydrogen quality, flow control, plant integration and operating flexibility are important for these projects.
Industrial hydrogen is used in refining, hydrogenation and chemical production.
When replacing or supplementing conventional hydrogen supply, the project should confirm:
Required gas purity
Process pressure
Continuous demand
Existing pipeline interface
Redundancy requirements
Plant safety standards
Hydrogen can be used in selected direct-reduction, protective-atmosphere and metallurgical processes.
Large industrial users typically focus on energy consumption, equipment availability, modular capacity and long-term service support.
An electrolyzer can provide on-site hydrogen for a refueling station when combined with suitable purification, compression, storage and dispensing equipment.
The complete station design must consider:
Daily vehicle demand
Filling pressure
Compressor capacity
Storage cascade
Hydrogen quality
Peak refueling periods
Equipment redundancy
Fuel-cell systems require hydrogen that meets the applicable purity and contaminant specifications.
The production system may require additional purification, drying, online analysis and quality documentation.
Electronics applications may require tightly controlled hydrogen purity, dew point and particle levels.
The gas-treatment and analytical system should be designed according to the user’s exact process specification.
Hydrogen can be used as a protective or reducing atmosphere in furnaces and thermal-processing equipment.
On-site production may provide a stable supply for operations with predictable continuous or batch demand.
An electrolyzer can convert excess wind, solar or other electrical energy into hydrogen.
The hydrogen may then be:
Stored
Used as industrial feedstock
Supplied to fuel cells
Converted into ammonia or methanol
Used for mobility
Blended or processed according to local regulations
The electrolyzer load range and control strategy should be matched to the renewable-power profile.
