Water Electrolyzer Market

Industry Overview

The Global Water Electrolyzer Market was worth USD 0.62 billion in 2023 and is expected to reach USD 58.5 billion by 2030 with a CAGR of 88.4% during the forecast period.

A water electrolyzer splits H2O into H2 and O2 using electricity. It has two electrodes in water, where an electric current triggers a reaction. At the cathode, H2 ions form, while at the anode, O2 is generated. This process, electrolysis, produces hydrogen and oxygen gases for clean energy.

The market is divided by its type into alkaline, PEM, solid oxide, and anion exchange membrane electrolysis where alkaline electrolyzers dominate. It is also divided into transportation, refining, power storage, ammonia and methanol production, and other sectors by its application, where ammonia production leads the market.

Insight by Electrolyzer Type

The global water electrolyzer market is divided into alkaline electrolysis, proton exchange membrane (PEM) electrolysis, solid oxide electrolysis, and anion exchange membrane electrolysis. Out of these segments, the alkaline electrolyzers dominates the market due to their established technology, affordability, and efficient hydrogen production. They use potassium hydroxide as an electrolyte solution, making them popular for large-scale production.

Insight by End-use Application

The global water electrolyzer market is divided into transportation/mobility, refining, power and energy storage, ammonia production, methanol production, and other industries. Among these segments, ammonia production leads the market due to its role in green energy and fertilizer industries. Electrolysis of hydrogen is integral to green ammonia production which uses renewable-driven electrolyzers to lower emissions.
