The global electrolyzer market has witnessed remarkable growth in recent years, driven by several key factors: 

1. Growing support from governments in the form of strategies, policies, initiatives, investments, and deployment targets

2. Rising adoption of hydrogen as a clean fuel due to its benefits

3. Growing interest in fuel cell electric vehicles (FCEVs) and hydrogen infrastructure

4. Increasing demand for hydrogen from industries

5. Rapidly growing low-carbon hydrogen production projects

However, factors such as high initial investments, a lack of hydrogen infrastructure, including distribution and storage facilities, and competition from other methods such as natural gas reforming are acting as restraints on the growth of the global electrolyzer market. 

Introduction

An electrolyzer is a device that employs electricity to facilitate the process of electrolysis, which involves passing an electric current through a substance to induce its decomposition into its fundamental constituent elements. This commonly involves the separation of water or other compounds into their primary components.

Currently, electrolyzers stand as the pivotal technology for generating hydrogen from water through the process of electrolysis. Water electrolysis is an electrochemical process that splits water (H2O) into hydrogen (H2) and oxygen (O2) using electricity. This process takes place in the electrolyzer.

The primary reason for producing hydrogen using an electrolyzer is to solve the intermittence issue caused by renewable energy sources, as hydrogen can be stored for longer durations when compared to any other energy storage method.

Working of an Electrolyzer

An electrolyzer comprises a conductive electrode stack separated by a membrane that is subjected to high voltage and current. This creates an electric current in the water, causing it to disintegrate into its constituents: oxygen and hydrogen.

The whole electrolyzer system includes pumps, power electronics, compressors, a gas separator, and other auxiliary components such as storage tanks. In some situations, the oxygen produced in parallel is discharged into the atmosphere or kept for future use as a medicinal or industrial gas.

Hydrogen is compressed or liquefied and stored to be used in industry or hydrogen fuel cells.

Types of Electrolyzers

There are four main electrolyzer technologies:

1. Alkaline Electrolyzer

2. Proton exchange membrane (PEM) / polymer electrolyte membrane electrolyzer

3. Others (Solid Oxide Electrolyzer Cells and Anion exchange membranes)

Electrolyzers have several major applications across various industries, primarily centered around the production and utilization of hydrogen. The major applications of electrolyzers include hydrogen production, chemical synthesis, space and aerospace applications, etc.

Drivers 

Growing Support from Governments

Governments around the world are increasingly recognizing the importance of hydrogen and electrolyzers in achieving their environmental and energy goals. They are enacting policies that incentivize and promote the use of green hydrogen produced via electrolysis. These policies often involve setting emission reduction targets and mandates for the integration of green hydrogen systems into various sectors, driving up demand for electrolyzers.

Prominent nations have taken significant steps by unveiling their hydrogen roadmaps as integral components of their energy transition strategies. For instance, in June 2023, the U.S. Department of Energy unveiled the U.S. National Clean Hydrogen Strategy and Roadmap. 

The roadmap not only encapsulates the current landscape of hydrogen production, transportation, storage, and utilization in the United States but also adopts a forward-looking perspective in the development of the green hydrogen market. It offers insights into how clean hydrogen will contribute to national decarbonization objectives and presents future demand scenarios for clean hydrogen. This, in turn, has the potential to catalyze increased demand for electrolyzer technology. 

In order to achieve their determined emission reduction targets promised in the international forums, governments are implementing incentive programs that offer financial support to companies and industries investing in electrolyzer technology. These incentives can take the form of grants, subsidies, tax credits, or rebates. Such programs reduce the financial burden on businesses looking to adopt or scale up electrolyzer projects.

For instance, the incentives announced in 2022 by the United States government under the Inflation Reduction Act led to an increase in the number of new electrolyzer manufacturing facilities in the nation, making way for the development of the hydrogen market in the nation.

Similarly, in April 2025, the European Union approved EUR 400 million for Spain's Hydrogen Scheme. This funding is set to support the construction of up to 345 megawatts (MW) of electrolyzer capacity and the production of up to 221,000 tons of renewable hydrogen in Spain.

Restraints 

Policy and Regulatory Uncertainty

Policy uncertainty remains a significant barrier to the global electrolyzer industry, as it creates an unpredictable environment for investment, project planning, and long-term market growth.

A key example is the U.S. Inflation Reduction Act (IRA), introduced under the Biden administration in 2022, which offered substantial incentives through the 45V production tax credits (PTCs)—up to USD 3/kg—based on the carbon intensity of hydrogen production.

These credits were made available to both green hydrogen projects, powered by renewable electricity and electrolyzers, and blue hydrogen projects, utilizing steam methane reforming with carbon capture, utilization, and storage (CCUS).

However, a shift in political leadership has altered the policy landscape. Under President Trump’s administration, the proposed tax bill titled “One Big Beautiful” advanced the eligibility deadline for 45V tax credits, requiring projects to begin construction by January 1, 2026, instead of the original January 1, 2033 deadline outlined by the IRA. These changes were reaffirmed in a revised bill released by the Senate Finance Committee on June 16, 2025.

This abrupt change poses a serious challenge for the hydrogen industry—especially for green hydrogen projects, which typically require long development timelines, significant upfront capital, and dedicated renewable energy sourcing.

Accelerating construction and achieving financial close within the newly shortened window is widely viewed as unrealistic, leading to growing hesitation among investors and project developers, and threatening to stall momentum in the U.S. electrolyzer market.

Segment Analysis by Type

As of the end of May 2024, approximately 1.75 GW of electrolyzer capacity had been deployed worldwide, while an additional 26 GW had reached Final Investment Decision (FID) globally.

Of the 1.75 GW deployed, around 60% of the capacity has a specified technology. Within this portion, alkaline electrolyzers account for roughly 75%, while proton exchange membrane (PEM) technology makes up the remaining 25%.

Regional preferences for electrolyzer technologies are also emerging. In China, around 90% of installed electrolyzers are alkaline, reflecting a preference for cost-effective, mature solutions.

Conversely, in Europe and North America, PEM technology dominates, comprising approximately 80% of deployed capacity, driven by its higher efficiency and suitability for dynamic operation with renewable energy sources.
