Electrolyzer Market: Powering the Green Hydrogen Revolution
The electrolyzers are used for the electrolysis of water. Through electrolysis, water is split into hydrogen and oxygen, which are further collected separately for use in industrial processes, automotive, power, and chemical industries. The electrolyzers are available in various sizes and have different methods of electrolysis.
Electrolyzer Market size was valued at USD 1.58 Billion in 2023 and is poised to grow from USD 1.91 Billion in 2024 to USD 5.18 Billion by 2032, growing at a CAGR of 21.2% during the forecast period (2025-2032).
