Green Hydrogen Production & Industrial Role

Green Hydrogen Production: Electrolysis and its Industrial Role

Aug 04, 2026

Introduction: Gray/Blue vs. Green Hydrogen—the decarbonization driver for ammonia and steel.
• Electrolyzer Chemistries Compared:
- Alkaline Electrolysis (AEL): Mature, low-cost nickel catalysts, caustic KOH liquid electrolyte.
- Proton Exchange Membrane (PEM): High operational flexibility, solid polymer electrolyte, iridium/platinum catalysts.
- Solid Oxide Electrolyser Cells (SOEC): High temperature (700–800°C), high efficiency.
• Chemical Processing Integration: Hydrogen storage, compression, and catalytic conversion into green ammonia or e-methanol.
