H₂ Infrastructure

Development of SMR-Based Hydrogen Infrastructure

  • SMR (Steam Methane Reforming, natural gas reforming) is one of the most widely adopted hydrogen production technologies worldwide, accounting for more than 70% of global hydrogen supply. This process produces hydrogen (H₂) by reacting natural gas (methane, CH₄) with high-temperature steam. Due to its high efficiency in large-scale production and strong economic feasibility, SMR is widely utilized as a core foundational technology for hydrogen infrastructure development.
  • The SMR process consists of two main chemical reaction stages:
    1) Methane Reforming Reaction
          - CH₄ + H₂O → CO + 3H₂
          - Conducted at high temperatures of approximately 700–900°C using a nickel-based catalyst
          - Primarily produces carbon monoxide (CO) and hydrogen (H₂)
    2) Water-Gas Shift Reaction
          - CO + H₂O → CO₂ + H₂
          - Reacts with additional steam to maximize hydrogen yield
          - After removing CO₂ from the resulting gas mixture, high-purity hydrogen (up to 99.99%) can be obtained
