Core Systems & Technical Features

1. Hydrogen Production System Adapted to High-Cold & Fluctuating Power
   The core production unit employs a high-cold adapted alkaline electrolyzer array, with equipment featuring reinforced insulation and cold-start design for stable operation in environments as low as -30°C. Deeply integrated with local wind/PV generation characteristics, the system is equipped with wide-power-range adaptive rectifier power supplies and an intelligent energy management system, achieving 100% utilization of green electricity and second-level response in adjusting production load. The specific energy consumption for hydrogen production reaches domestically leading levels.
2. Low-Temperature Resistant High-Pressure Storage & Fast Refueling System
   • Storage System: Adopts a combined design of 45MPa high-pressure hydrogen storage vessel banks and pipeline buffer storage. Critical valves, instruments, and piping use low-temperature rated materials and are equipped with trace heating systems to ensure safe operation under extreme cold.
   • Refueling System: Features dual-pressure level (35MPa/70MPa) hydrogen dispensers, integrating efficient pre-cooling and low-temperature adaptive control algorithms. This enables fast and safe vehicle nozzle coupling in high-cold environments, with refueling time for a single heavy-duty truck ≤10 minutes.
   • Hydrogen Quality Assurance: Online purity monitors and trace impurity analyzers ensure the produced hydrogen meets the highest standards of GB/T 37244.
3. Station-Wide Intelligent Control & Digital Twin O&M Platform
   A Digital Twin-based Station Control System is established for real-time forecasting and optimized dispatch of renewable resources, production load, storage status, and refueling demand. The platform enables remote intelligent diagnostics, fault prediction, lifecycle management, and connects to the regional energy big data platform for real-time carbon footprint tracking and certification.
4. Comprehensive Safety Design for High-Cold Environments
   The design follows the triple principle of "Prevention, Control, and Emergency," integrating:
   • Freeze & Condensation Protection: Process piping with electric trace heating and insulation, freeze-proof treatment for vent systems.
   • Inherent Safety Enhancement: Upgraded explosion-proof ratings for the production area, added low-temperature impact resistant barriers for the storage area.
   • Emergency Safety Systems: Deployment of firefighting media and emergency heating equipment specifically designed for extreme cold climates.

 

EPC Turnkey Delivery & Localized Integration
Addressing the challenges of the first demonstration project in a high-cold region, the company provided full-cycle EPC services covering preliminary resource matching analysis, customized design, cold-resistant equipment selection, construction management for extreme climates, digital delivery, and localized O&M system establishment. The project successfully tackled key technical challenges such as smooth control of hydrogen production using fluctuating renewable power, reliability of hydrogen-related materials and equipment in extreme cold, and economical operation of multi-energy coupled systems, resulting in a replicable, scalable solution for green hydrogen stations in high-cold regions.
