Industry Overview

Power Transmission Solutions

The overall solution for hydrogen refueling stations constitutes a specialized integration system of engineering technologies. At its core is the establishment of a complete, efficient, and highly reliable technical chain for hydrogen handling, encompassing the stages of reception/preparation, purification, compression, storage, and refueling. This system typically comprises four principal subsystems: the front-end hydrogen supply module (comprising gas unloading units or on-site hydrogen generation systems such as electrolyzers or reformers), the high-pressure processing unit (including compressors, sequence control panels, and high-pressure hydrogen storage arrays), the refueling terminal (featuring pre-cooling units and hydrogen dispensers), and the integrated station control and safety management system.
