This project involves a 500 Nm³/h water electrolyzer hydrogen generator unit exported to a Middle Eastern country, independently developed and manufactured by our company. The unit completed production and shipment in August 2025, and successfully passed on‑site commissioning and entered operation in April 2026, with hydrogen purity meeting all acceptance criteria. The successful implementation of this project marks another significant milestone in our company's expansion into overseas hydrogen equipment markets. 

Project Background：

As the global energy transition accelerates, hydrogen has gained increasing international recognition as a key carrier of clean energy. The Middle East enjoys abundant solar and wind resources, giving it a natural advantage for developing green hydrogen. In recent years, the government of this country has begun to lay out its hydrogen industry, making it an integral part of its energy transition and shift toward cleaner energy. 

Against this backdrop, our company secured the order for this 500 Nm³/h water electrolyzer hydrogen generator unit, leveraging our independently developed high‑efficiency electrolyzer core technology and extensive experience in overseas projects. This project provides critical equipment support for the country's green hydrogen industrial chain and represents a significant practice of Chinese hydrogen equipment entering the global market. 

Project Scale & Technical Solution：

Core Equipment Specifications：

The core equipment is a 500 Nm³/h alkaline water electrolyzer (ALK) with the following key parameters:

System Composition：

The water electrolysis system adopts a modular design and mainly consists of:

- Electrolyzer: Featuring new electrode and diaphragm materials, offering high current density and low energy consumption

- Gas‑liquid processor (skid): For efficient separation and treatment of hydrogen and oxygen

- Control system: PLC‑based automatic control with remote monitoring and operation capabilities

- Auxiliary systems: Including water feed pump, alkali‑water tank, rectifier cabinet, rectifier transformer, flame arrestor, etc.

The unit offers the following core advantages:

- High efficiency & energy saving: Advanced electrolyzer design and efficient power management system result in low energy consumption and high hydrogen production efficiency

- High‑purity hydrogen: Hydrogen purity can reach over 99.999%, meeting both industrial and energy‑grade standards

- Modular design: Compact structure with high integration, facilitating transportation, installation, and maintenance

- Intelligent control: Real‑time data acquisition and fault diagnosis ensure safe and stable operation

Project Implementation Timeline

Production Phase (before August 2025)

After project initiation, our company rapidly mobilized R&D, production, quality control, and other departments for coordinated progress. From core component machining to final assembly, every process was strictly controlled in accordance with international standards and customer requirements. Following rigorous manufacturing and quality inspection, the unit was successfully completed and shipped in August 2025. 

Shipping & Transportation (August 2025)

After production, the unit was transported to the destination country by sea. Our company dispatched a professional technical team to accompany the shipment, ensuring the safety and integrity of the equipment during long‑distance transport. 

On‑site Commissioning (April 2026)

Upon arrival, our technical team immediately began installation and commissioning work. Despite challenges posed by local climatic conditions and infrastructure, the team efficiently overcame difficulties and advanced the process:

1. Positioning & installation: Completed lifting, positioning, and foundation fixing

2. System integration: Conducted joint commissioning of the electrolyzer, gas‑liquid processor, control system, and other subsystems

3. Load testing: Performed cold start, hot start, variable load operation, and continuous rated load operation tests

4. Performance verification: Comprehensively tested key indicators including hydrogen production rate, energy consumption, and purity

Successful Start‑up (April 2026)

In April 2026, the unit successfully completed continuous stable operation at full load, with all parameters meeting design requirements. Hydrogen purity passed the commissioning acceptance smoothly. The project then officially entered commercial operation.
