Integrated Hydrogen Production & Refueling Station
An integrated hydrogen production and refueling station is a facility that supplies hydrogen to hydrogen fuel cell vehicles, similar to how traditional gas stations provide fuel for gasoline and diesel vehicles. It usually consists of equipment for hydrogen storage, compression, delivery and dispensing, with hydrogen compressors and hydrogen storage tanks as the core equipment.
■ System Composition
■ Technical Features of Integrated Hydrogen Production
· Modular hydrogen production equipment with high integration, requiring little on-site installation work.· Small footprint, making it feasible to renovate existing CNG refueling stations into integrated hydrogen production-refueling stations.
· Low overall equipment height, different from traditional industrial-scale hydrogen production units.
· High degree of automation with minimal manual intervention.
■ Technical Features of Compression Equipment
· Diaphragm compressors are adopted, ensuring no hydrogen contamination and high hydrogen purity to meet fuel cell requirements.· Diaphragm compressors feature a high compression ratio; two-stage compression suffices for high-pressure hydrogen storage and refueling at refueling stations with a simple compressor structure.
· Simple compressor structure, easy for skid-mounted assembly and convenient on-site installation.
· Multiple domestic diaphragm compressor suppliers are available, promoting the sound development of related domestic industries.
■ Technical Features of Hydrogen Storage Equipment
· High-quality domestic high-pressure hydrogen storage cylinder cascades are used, with a single vessel volume of 1–2 m³, large hydrogen storage capacity and high reliability.
· Multi-stage hydrogen storage is adopted, which can be divided into 3–4 stages according to demand, achieving high volume utilization efficiency of the storage cylinder cascades.
■ Technical Features of Hydrogen Refueling & Cooling System
· Hydrogen refueling equipment from mature domestic manufacturers is used, featuring accurate metering, automatic control of refueling speed, high safety and simple operation.
· Skid-mounted chiller with small footprint; chilled water temperature is adjustable from -30°C to 10°C, offering a wide application range.
■ Overall System Features
· Containerized skid-mounted design with high integration and small footprint.
· Unified intelligent control system with high automation.
· Wide operating flexibility, allowing hydrogen production equipment to stand by.
· Easy to promote by renovating and expanding existing natural gas refueling stations.
