Alkaline electrolysis is recognized as one of the most advanced and widely adopted technologies for hydrogen production. In this method, two electrodes are immersed in an alkaline electrolyte solution- KOH, which enables the conduction of OH- anions.
Advantages
- Low operational cost due to usage of non-noble materials as catalysts
- Relatively high production efficiency
- Large-scale capability
- Effectively integrated with renewable energy
- Low investments costs
