    Rubri 2MW 5MW 10MW Alkaline Water Electrolysis Plant ...
    A 100 Nm³/h alkaline electrolysis system is an industrial-grade, green hydrogen generator producing approximately 215-220 kg of hydrogen per day (at 99.999% purity). These systems typically consume 500-600 kW of power (~4.8–5.5 kWh/Nm³) and operate at pressures up to 1.6 MPa, suitable for industrial, energy, or refueling applications. 
    Typical Specifications (100 Nm³/h) 
    • Hydrogen Production Rate:

    Core Components 
    An alkaline electrolyzer system for this capacity generally includes: 
    1. Electrolyzer Stack: The core, using nickel-based electrodes and a potassium hydroxide (KOH) electrolyte.
    2. Gas-Liquid Separation: Separates hydrogen/oxygen from the KOH solution.
    3. Purification Unit: Removes water and contaminants for high-purity
      H2cap H sub 2
      𝐻2
      .
    4. Power Supply (Rectifier): Converts AC to DC for the electrolysis process.
    5. Water Treatment & Cooling: Supplies pure water and maintains operating temperatures around 90°C. 
    Applications 
    • On-site Hydrogen Generation: Industrial processes, material handling, or power-to-gas.
    • Mobility: Powering hydrogen refueling stations for vehicles.
    • Energy Storage: Converting renewable electricity into hydrogen. 
    These plants can often operate between 40-110% of their rated capacity (40–110 Nm³/h) to allow for flexibility, particularly with intermittent renewable energy sources.
