AI Overview
Core Components
An alkaline electrolyzer system for this capacity generally includes:
- Electrolyzer Stack: The core, using nickel-based electrodes and a potassium hydroxide (KOH) electrolyte.
- Gas-Liquid Separation: Separates hydrogen/oxygen from the KOH solution.
- Purification Unit: Removes water and contaminants for high-purity .
- Power Supply (Rectifier): Converts AC to DC for the electrolysis process.
- 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.
