Wei Zhikun, Marketing General ManagerTapping into hydrogen’s transformative potential through a proprietary water electrolysis process, Tianjin Mainland Hydrogen Equipment (THE) has established itself as a leader in the industry. Delivering cutting-edge solutions for hydrogen production and purification, THE leverages over three decades of expertise to set new benchmarks in technology and safety.
Backed by a skilled team of professionals, THE is committed to delivering exceptional after-sales service, offering comprehensive technical support and tailored recommendations to ensure every plant’s safety and optimal performance.
“Clients often choose to purchase additional electrolyzers or replace existing ones with Tianjin products due to the high quality demonstrated by the product,” says Wei Zhikun, marketing general manager.
Delivering Unmatched Hydrogen Purity
Central to THE’s success is its groundbreaking “separation flow process,” a technological breakthrough that redefines hydrogen production. This innovative method enables the independent separation of hydrogen and oxygen during electrolysis, resulting in an impressive O2 purity of 99.5 percent. Such a high level of purity is crucial for the safe and efficient operation of hydrogen generators while effectively addressing the common industry challenge of poor oxygen purity.
THE’s hydrogen production process enhances operational efficiency by optimizing electrolyte circulation, reducing energy consumption and maintaining high production levels. Its electrolyzers, with production capacities ranging from one to 1,000 cubic meters per hour, are designed for high-pressure operation: up to 50 bar for smaller systems and 30 bar for larger ones. Advanced sealing materials and innovative sealing structures minimize the need for additional equipment, improving efficiency and overall performance. This design eliminates the need for downstream compressors, significantly lowering capital and operational costs without compromising performance.
Carefully selecting advanced materials and membranes for its electrolyzers, THE enhances system efficiency while significantly reducing power consumption. Plants with its electrolyzer installed consume only 4.3 kW of electricity per cubic meter of hydrogen produced, underscoring energy efficiency.
THE’s hydrogen generation equipment features automatic gas output adjustment, ensuring safe operation even during load fluctuations. This makes it ideal for renewable energy applications where power supply is unstable.
The growing demand for efficient and cost-effective systems has driven THE to develop advanced remote monitoring and control capabilities. Over 20 years ago, it introduced unattended operation, supplying its first remote-controlled system to a European customer. These systems allow operators to manage hydrogen plants from up to 50 kilometers away, enabling prompt issue resolution without constant onsite supervision.

With the user’s permission, this remote control function also allows THE to monitor equipment operation, prevent malfunctions, analyze fault causes, and resolve issues. This technology enables THE to deliver seamless solutions for integrated system management. As renewable energy projects expand in scale and complexity—often incorporating multiple hydrogen generation subsystems—its integrated approach ensures precise control over each hydrogen plant’s capacity, startup, and shutdown processes.
THE has also taken a leading role in advancing hydrogen purification. Its hydrogen purifier is distinguished by its zero regeneration gas consumption, eliminating a major source of operational waste common in traditional systems. Using innovative three-dry technology enhances equipment performance, reduces operational costs and ensures efficient, uninterrupted purification.
With a maximum purification capacity of up to 20,000 Nm³/h, the purifier meets the needs of large-scale industrial operations with impressive efficiency and reliability. Clients can utilize hydrogen for internal operations and supply it to external customers with varying purity requirements. The system incorporates advanced impurity removal processes. Sampling and analysis ensure that contaminants like methane, CO, CO₂, hydrocarbons, and N₂ are reduced to parts per billion (PPB) levels, delivering exceptionally high-purity outputs for sensitive applications where even trace amounts of contamination could compromise product quality.
Innovative Engineering for Reliable Hydrogen Production
Demonstrating its reliability and ability to handle high-capacity projects, THE has successfully supplied thousands of hydrogen plants across industries worldwide. Its solutions have made a significant impact, from chemical processing and oil refining to electronics and renewable energy. With a strong foothold in Europe, Southeast Asia, North America, and the Middle East, THE has supplied equipment to over 500 companies worldwide, with more than 1,400 projects deployed across various regions. THE has earned the trust of prominent clients, including Baosteel, Samsung, Wilmar, and Air Liquide, Linde.
A recent project in Southeast Asia showcases the company’s engineering expertise and ability to deliver customized solutions. Departing from standard designs, the project required two stacks and a single gas-liquid separation system integrated with one purification unit to meet the client’s specific needs and minimize project investment costs. THE provided 2 * 5MW hydrogen generation equipment to a solar energy production enterprise located in northwest China, where it has been continuously operating for more than six years.
With a proven track record of innovative solutions and a strong commitment to customer support, Tianjin Mainland Hydrogen Equipment continues to be a driving force in the hydrogen energy revolution.
