Alkaline Water Electrolysis, valued at $12.85 billion in 2025, is projected to reach $43.11 billion by 2035. Its next-generation successor, Anion Exchange Membrane electrolysis, grows at an extraordinary 87.4% annually. Companies like Nel Hydrogen, Siemens Energy, Enapter & Thyssenkrupp Uhde lead commercialisation across continents. Government policies in the US, EU & India are accelerating deployment at gigawatt scale, making clean hydrogen production a near-term industrial reality
