Core Systems & Technical Architecture

1. Ultra-Large-Scale Hydrogen Storage & Multi-Stage Compression System
   The station integrates a modular high-pressure hydrogen storage system with a total volume exceeding 120 cubic meters, operating at dual pressure levels of 45MPa and 90MPa. It is equipped with six independently operable, parallel liquid-driven compressor units, each with a 500 kg/day capacity. Intelligent dispatch enables dynamic allocation and redundant backup of the hydrogen source, ensuring stable output of the 3,600 kg/day capacity even during peak periods.
2. Full-Scenario Dispensing Terminals & High-Efficiency Flow Management
   The station is configured with 12 dual-nozzle hydrogen dispensers, supporting simultaneous operation at both 35MPa and 70MPa pressure levels, allowing 24 hydrogen fuel cell vehicles to refuel concurrently. The system incorporates an adaptive pressure-flow coupling control algorithm that optimizes the refueling curve in real-time based on vehicle type and ambient temperature, reducing single refueling time by over 15% compared to industry standards.
3. Multi-Layer Intelligent Safety & Risk Prevention System
   The project establishes the world's first "Three-Level Risk Isolation, Four-Level Intelligent Monitoring" safety architecture in the hydrogen station sector:
   • Physical Isolation: Independent layout of storage, compression, and dispensing zones, equipped with blast walls and directional pressure relief devices.
   • Process Monitoring: Incorporation of fiber optic sensing and laser gas imaging technology for real-time imaging and of micro-leaks across all station piping.
   • Emergency Response: An Emergency Shutdown System (ESD Level 2) with self-diagnostic capabilities and a fault response time of <200 milliseconds.
4. Intelligent Energy Management & Digital Twin Operation Platform
   A dynamic simulation system for the entire station is built on digital twin technology, enabling:
   • Supply-Demand Forecasting: Intelligent prediction of refueling peaks using traffic flow data for pre-emptive compressor scheduling.
   • Equipment Health Management: Predictive maintenance for compressors through fused analysis of vibration, temperature, and current parameters.
   • Carbon Footprint Tracking: Real-time calculation of carbon reduction per refueling event and automatic generation of green hydrogen consumption certification reports.

Engineering Execution & System Integration Breakthroughs
As an ultra-large-scale, complex hydrogen infrastructure project, it successfully overcame world-class engineering challenges such as vibration suppression in multi-compressor parallel operation, fatigue life optimization for large-scale high-pressure piping, and validation of safety interlock logic
