Global Electrolyzer Market - Growth, Trends, and Forecast to 2029

Global Electrolyzer Market - Growth, Trends, and Forecast to 2029

Updated on 21st March 2024 | Market Research Reports | Q1 2024 | Report ID: BR0336

About the Report

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

  • Growing support from governments in the form of strategies, policies, initiatives, investments, and deployment targets
  • Rising adoption of hydrogen as a clean fuel due to its benefits
  • Growing interest in fuel cell electric vehicles (FCEVs) and hydrogen infrastructure
  • Increasing demand for hydrogen from industries
  • 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. 



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 electrolysis of water. 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:

  • Alkaline Electrolyzer
  • Proton exchange membrane (PEM) / polymer electrolyte membrane electrolyzer
  • Solid Oxide Electrolyzer 
  • Anion exchange membranes (AEMs) (SOCEs and AEMs are Emerging Technologies)


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.



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.

Segment Analysis by Type

In 2023, 12 GW of electrolyzer capacity reached the Final Investment Decision (FID) globally. Notably, about 80% of these projects utilized alkaline technology, while 20% adopted proton-exchange membrane (PEM) technology. This distribution suggests a stable share for PEM technology. Within China, a substantial 90% of the deployed electrolyzers are alkaline electrolyzers. In contrast, PEM technology is more prevalent in Europe and North America, constituting 80% of the total installed capacity in these regions.

Regional Analysis

Progress in electrolyzer development spans across various continents, with China taking the lead in installed capacity, while the European Union and the United States have implemented significant policy initiatives.


Countries and regions that are making noteworthy strides in advancing electrolyzer technology include:


China: China stands at the forefront in both electrolyzer capacity and manufacturing. As of October 2023, the country had a cumulative electrolyzer capacity of nearly 610 MW, with an additional 6.6 GW of electrolyzer projects having passed the FID (final investment decision). Remarkably, China accounts for 40% of the global electrolyzer manufacturing capacity, highlighting its substantial contribution to the industry's growth.


Europe: As of October 2023, the region has a cumulative electrolyzer capacity of 220 MW. Major nations contributing to this capacity are Germany with 60 MW, Spain, and Sweden with 25 MW each. In July 2022, the European Commission gave the green light to EUR 5.4 billion in funding to bolster its inaugural hydrogen-related Important Project of Common European Interest (IPCEI), known as Hy2Tech. This initiative focuses on advancing hydrogen technologies and includes incentives to support electrolyzer manufacturers, further promoting the development of this critical sector. 


North America: The United States is the leading nation in terms of electrolyzer capacity deployment, with 60 MW by the end of October 2023. The nation introduced pivotal incentives through the Inflation Reduction Act (IRA). These incentives encompassed credits designed to finance manufacturing projects, and their impact is already being realized. There has been a notable uptick in announcements regarding new electrolyzer manufacturing facilities in the country, signaling a burgeoning commitment to electrolyzer technology and its broader implications.


Current Scenario of the Electrolyzer Industry

In 2023, the deployment of electrolysis capacity experienced substantial growth, surging by approximately 60% compared to 2022, reaching a total of 1.1 GW, a significant increase from the previous 700 MW. This installed capacity translates to approximately 150 kilotons per annum (kt p. a.) of renewable hydrogen supply. 


The primary driver behind this growth is the substantial addition of electrolyzer capacity in China. Presently, China holds the lead in deployed electrolyzer capacity, with 610 MW. Notably, the world's two most significant operational projects, each with capacities of 260 MW and 150 MW, are situated in China. Following China, the United States and Germany have notable capacities, each at 60 MW. Additionally, Spain, Taiwan, Sweden, and Canada each contribute approximately 25 MW to the global electrolyzer capacity landscape.


Taking into account the robust pipeline of projects currently under development and their anticipated operational dates, it is anticipated that global electrolysis capacity will experience a swift and substantial expansion in the forecast period.
