Core equipment for hydrogen energy infrastructure refers to a series of major technological equipment used in key aspects of the entire hydrogen energy industry chain, including hydrogen production, storage, transportation, and refueling.
- High-Tech Integration: Integrates multiple cutting-edge technologies including materials science, precision manufacturing, automation control, and safety monitoring, resulting in high technological barriers.
- High Safety Requirements: Due to the flammable, explosive, and leak-prone nature of hydrogen, all core equipment must meet extremely stringent safety design standards and specifications.
- Adaptability to Harsh Operating Conditions: Some equipment needs to withstand high pressure (e.g., 70MPa hydrogen storage cylinders), ultra-low temperatures (e.g., -253℃ liquid hydrogen), or highly corrosive working environments.
- Strong System Coordination: The various pieces of equipment require high coordination to form a seamless system, ensuring the stability and efficiency of the hydrogen energy supply chain.
Clean and efficient: Hydrogen production equipment coupled with renewable energy sources (such as alkaline and PEM electrolyzers) can achieve “zero-carbon” hydrogen production from the source, aligning with global energy transition trends.
Prominent energy carrier role: High-pressure gaseous and liquid storage and transportation equipment enables large-scale, long-distance, and flexible allocation of hydrogen energy across time and space, effectively addressing the issues of renewable energy consumption and fluctuations.
Rapid refueling and long driving range: The core equipment of hydrogen refueling stations provides fuel cell vehicles with a rapid refueling experience similar to gasoline vehicles (3-5 minutes), achieving a driving range of over 700 kilometers, resulting in a superior user experience.
Leading industrial upgrading: The independent research and development and manufacturing of core equipment will drive the development of related industrial chains such as high-end materials, precision components, and intelligent control, representing a significant growth point for strategic emerging industries.
The complete process flow of hydrogen energy infrastructure revolves around core equipment, forming a closed-loop chain:
Production Stage
Process: Hydrogen production through water electrolysis (alkaline electrolyzer, proton exchange membrane (PEM) electrolyzer).
Core Equipment: Electrolyzer and its system (including power supply, pure water system, gas-liquid separator, etc.).
Purification and Drying Stage
Process: Purification and dehydration of the produced crude hydrogen to meet the high-purity requirements of fuel cells and other applications.
Core Equipment: Hydrogen purification unit, dryer.
Storage and Transportation Stage
Process:
Gaseous storage and transportation: Hydrogen is pressurized to 20-45 MPa using a compressor and transported in tubular trailers or tubular containers.
Liquid storage and transportation: Hydrogen is deeply frozen to -253°C and liquefied, then transported in liquid hydrogen storage tanks (high energy density).
Core Equipment: Hydrogen compressor, high-pressure hydrogen cylinder/tank, tubular trailer, liquid hydrogen storage tank.
Refueling Process
Process: At hydrogen refueling stations, fuel cell vehicles are safely and quickly refueled using on-site compressors, hydrogen storage tanks, cooling systems, and hydrogen refueling machines.
Core Equipment: Station-use hydrogen compressors, hydrogen storage tanks, and hydrogen refueling machines.
