Water Electrolysis Market - A Global and Regional Analysis: Focus on End-Use Application, Electrolyzer Type, and Region - Analysis and Forecast, 2025-2034

Global Water Electrolysis Market Industry Overview

An electrolyzer is a system that breaks water into hydrogen and oxygen with the help of electricity. This process is known as electrolysis and it is mainly used to produce hydrogen, which is then stored as a compressed or liquefied gas. Oxygen produced during the electrolysis process is either released into the atmosphere or is stored to use for other purposes.

International Energy Agency (IEA) has projected that the energy demand will grow between 25% to 30% by 2040 with companies and governments trying to find sustainable and low-carbon emission energy sources. Hydrogen is being called the fuel of the future and IEA has projected that hydrogen production from water electrolysis can prevent the 830 million tons of CO2 annually from entering the atmosphere. Moreover, the growing demand for hydrogen fuel cell vehicles, green ammonia, green methanol, and other applications is driving the growth of the water electrolysis market.

Water Electrolysis Market Lifecycle Stage

Water electrolysis is old technology and was first introduced in 1789 by the Dutch merchants Jan Rudolph Deiman and Adriaan Paets van Troostwijk, who used gold electrodes and an electrostatic generator to produce an electrostatic discharge in water. Almost 100 years later in 1888, Russian engineer Dmitry Lachinov developed the first industrial water electrolyzer for producing hydrogen and oxygen. In the mid-1960s, General Electric introduced the proton exchange membrane process for the Gemini Space Program, and it was later adopted for hydrogen production. Currently, there are four types of electrolyzers available in the market alkaline and polymer electrolyte membrane (PEM) already commercialized and anion exchange membrane (AEM) and solid oxide at an early stage of commercialization.

Industrial Impact

The growth of the water electrolysis market is closely tied to the hydrogen and ammonia market. Water electrolysis is one of the clean methods for the production of hydrogen and is highly sustainable as there are no emissions and the feedstock used for hydrogen production is water. The growing demand for green hydrogen and green ammonia are among the major drivers of the growth of the water electrolysis market.

Market Segmentation:

Segmentation 1: by End-Use Application

• Transportation/Mobility Industry
• Refining Industry
• Power and Energy Storage
• Ammonia Production
• Methanol Production
• Other End-Use Applications

Segmentation 2: by Electrolyzer Type

• Alkaline Electrolyzer
• Proton Exchange Membrane (PEM) Electrolyzer
• Solid Oxide Electrolyzer Cell (SOEC)
• Anion Exchange Membrane (AEM) Electrolyzers

The water electrolysis market is dominated by alkaline electrolyzers owing to the large-scale application of alkaline water electrolysis. Moreover, the first commercialized water electrolysis systems were based on alkaline water electrolysis. The low cost and technological maturity of alkaline water electrolyzers further support the dominant share of these electrolyzers in the market.

Segmentation 3: by Region

• North America - U.S., Canada, and Mexico
• Europe - Germany, France, Netherlands, U.K., Spain, and Rest-of-Europe
• Asia-Pacific - China, Japan, India, South Korea, Australia, and Rest-of-Asia-Pacific and Japan
• Rest-of-the-World - South America, Middle East and Africa

Asia-Pacific and Japan are anticipated to gain traction in terms of the water electrolysis market owing to the presence of a large number of players, growing demand for green hydrogen, investment from the government, and the large fleet of fuel-cell vehicles in the region. Moreover, the rising demand for green ammonia and the development of hydrogen infrastructure in the region are expected to further support the dominant share of the region in the market.

Recent Developments in the Water Electrolysis Market

• In June 2022, Bosch announced that it will invest $1.3 billion by 2025 in hydrogen. The company has already invested significantly in fuel cell technology and the company is now planning to leverage its expertise in fuel cell technology to develop electrolyzers with an investment of $600 million by 2030.
• In June 2022, De Nora Water Technologies and Saline Water Conversion Corporation (SWCC) announced that they have expanded their partnership and had signed a memorandum of understanding (MOU) for brine mining and water electrolysis research.
• In June 2022, Hyundai Engineering & Construction (Hyundai E&C) announced that the Ministry of Trade, Industry, and Energy has chosen the company for building a water electrolysis-based hydrogen production base project. The company will be responsible for building a base for producing, storing, and transporting more than one ton of hydrogen per day.
• In May 2022, Frontier Energy Ltd. announced that it has chosen alkaline water electrolysis (AWE) as the preferred electrolysis technology for the production of green hydrogen at the Bristol Springs Solar (BSS) Project south of Perth in Western Australia. The company chose AWE over other water electrolysis technologies due to its low cost and technological robustness.
• In April 2022, ThyssenKrupp nucera announced that Air Products has selected the company for the supply of its alkaline water electrolysis technology to produce green liquid hydrogen in Casa Grande, Arizona in a 10 metric ton per day facility.

Demand - Drivers and Limitations

Following are the demand drivers for the water electrolysis market:

• Growing demand for green hydrogen for green ammonia and green methanol
• Rising investment and favorable policies from the government
• Hydrogen demand for energy storage

The market is expected to face some limitations too due to the following challenges:

• High capital investment requirement for water electrolysis
• Highly volatile prices of precious metals like iridium, ruthenium, and platinum used as a catalyst in water electrolysis
