Green Hydrogen Project Tracking—CRRC's First Megawatt-Level PEM Hydrogen Production System Successfully Rolls Off the Line and Achieves Full Power Operation

On November 27, the first megawatt-level PEM hydrogen production system independently developed by CRRC was successfully launched and achieved full power operation. This milestone event marks a solid step for CRRC in the field of PEM hydrogen production technology, adding new momentum to the development of China's clean energy equipment.

PEM hydrogen production technology, due to its alignment with the intermittent and fluctuating characteristics of renewable energy, holds significant application advantages in hydrogen production projects using fluctuating power sources such as wind and solar power. The megawatt-level PEM hydrogen production system developed by CRRC this time demonstrates outstanding core performance indicators, with DC energy consumption less than 4.2 kWh/Nm³, reaching the advanced level in the industry according to actual measurements.

The system features comprehensive design in terms of safety and reliability, integrating the concepts of high safety and high reliability throughout the entire life cycle, including design, verification, integration, operation, and maintenance. Among these, the electrolyzer employs key technologies such as highly reliable hydrogen elimination membrane electrodes, special-shaped interface sealing design, and efficient component matching processes, effectively reducing hydrogen leakage and hydrogen production energy consumption. The post-treatment system ensures the stability and safety of equipment operation through hydrogen-oxygen equal-pressure design and micro-differential pressure regulation, highly reliable instrument and valve configurations, and multi-level safety protection and monitoring.

In terms of deployment and application scenarios, the system adopts a containerized design, offering the advantages of flexible transportation and easy rapid deployment, enabling it to adapt to complex environments such as offshore platforms and deserts. Its application scope is wide, suitable for scenarios such as wind-solar power coupled hydrogen production, energy supply in remote areas, and green hydrogen replacement in chemical industries. The high-purity hydrogen produced can be directly supplied to fuel cells or chemical production, not only effectively reducing storage and transportation costs but also reducing carbon emissions, contributing to green and low-carbon development.

The successful commissioning and operation of the megawatt-level PEM hydrogen production system serve as strong evidence of CRRC's active implementation of the national "dual carbon" strategy and its full efforts to build an industrial development pattern of "dual tracks and dual clusters." In the future, CRRC will continue to focus on new energy application scenarios, deepen technological exploration and innovative practices, and continuously provide efficient and reliable clean energy equipment solutions, injecting strong momentum into accelerating the achievement of the "dual carbon" strategic goals.
