Recently, the "Hydrogen Wind Fears No Myriad Mountains" PV+ESS-Hydrogen Integration Technology Seminar, co-hosted by Jiangsu Trina Green Hydrogen Technology Co., Ltd. and the Hydrogen Energy Industry Branch of the China Industrial Development Promotion Association, was held in Yangzhou. Over a hundred representatives from industry associations, central state-owned energy enterprises, design institutes, university research institutions, and hydrogen energy equipment enterprises attended, jointly discussing technological innovation and large-scale application paths for PV+ESS and hydrogen integration.
At the seminar, Trina Green Hydrogen released a full-chain technology portfolio including an empirical platform, core equipment, grid-forming PV+ESS-hydrogen integration technology, and a digital twin operation center, and proposed solutions for stable hydrogen production system operation and digital control under fluctuating renewable energy conditions.
Currently, renewable energy development is shifting from scale expansion to systemic value enhancement. As installed wind and PV capacity continues to grow, issues such as insufficient grid absorption capacity, widening peak-shaving gaps, and power supply fluctuations are becoming increasingly prominent, driving rising industry demand for integrated systems that are verifiable and digitally controllable.
Meanwhile, upstream electrolyzer manufacturing in the green hydrogen industry still faces challenges such as insufficient process cohesion, high labour dependency, relatively scattered quality data, and inadequate full-process traceability, which constrain large-scale equipment production efficiency and product consistency.
To address these challenges, Trina Green Hydrogen demonstrated for the first time its fully automatic alkaline electrolyzer stacking production line, which is already in operation. This line enables fully automated assembly from parts to the complete electrolyzer and supports flexible production of electrolyzers ranging from 500 to 2,000 standard cubic meters.
The production line is equipped with AI visual positioning detection and real-time monitoring and traceability of stacking parameters. Through custom fixtures and dual-stage visual positioning, it achieves automatic flat gripping and fixation of the separator, completely replacing manual laying. Full vision tracking inspection technology ensures high assembly accuracy for the electrolyzer, with electrode perpendicularity not exceeding 0.3%, and installation accuracy for the separator to the step and separator flatness both reaching 0.5 mm.
Compared with traditional semi-automated lines, this production line focuses on addressing issues such as high labour requirements, low production efficiency, inconsistent assembly accuracy, and data discontinuity, thereby providing technical support for the large-scale, standardized, and stable production of hydrogen production equipment.
