IDTechEx forecasts the annual water electrolyzer market value to exceed US$70 billion by 2034, representing a CAGR of 40.7% over 2024-2034. This growth is driven by the increasing focus from companies and governments on developing green hydrogen plants to decarbonize hard-to-abate industries. Hydrogen demand is expected to grow globally from incumbent applications, including refining and ammonia production, as well as from new markets such as in methanol, green steel, and transport applications. Additional growth drivers include the continued development and innovation of water electrolysis technologies and installation of large electrolyzer manufacturing capacities worldwide.
Continuing its exploration of the green hydrogen space, IDTechEx has updated its Green Hydrogen Production: Electrolyzer Markets 2023 report for 2024, building on existing research.

The need for green hydrogen and advanced electrolyzer technologies
Global activities in the hydrogen sector have intensified, with a drive from governments, industries, and corporations to transition to a hydrogen economy for decarbonizing sectors that are difficult to electrify directly. Green hydrogen - produced through water electrolysis powered by renewable energy - has emerged as a key decarbonization solution, propelled by governmental ambitions to establish substantial gigawatt (GW) scale electrolyzer manufacturing and green hydrogen production capacities by the end of this decade.
The pivot to green hydrogen goes further than the goal of low-carbon hydrogen production to replace existing grey hydrogen sites - it is a strategic move to decarbonize industries where electrification is not feasible, such as heavy industry (e.g. petroleum refining) and various transportation sectors (e.g. shipping). These sectors, crucial yet challenging in terms of emissions reduction, can leverage hydrogen as a potent and clean energy vector. Additionally, the integration of green hydrogen into the energy mix could enhance energy security and pave the way for new market opportunities in renewable energy storage and coupling of various sectors.
Nonetheless, green hydrogen faces many commercial and technical challenges. Among the key hurdles are access to cheap renewable energy with high capacity factors as well as low-cost, efficient and durable electrolyzer systems. The latter necessitates improvement and development of advanced electrolyzer technologies. Moreover, projects need to demonstrate viable business cases and models, which is especially challenging for newer hydrogen applications like renewable energy storage. The report sheds light on some additional challenges.
Overview of the green hydrogen plant and types of water electrolyzer technology. Source: IDTechEx
Electrolyzer technology
There are four main types of electrolyzer technology that can be used to produce green hydrogen: alkaline water (AWE or AEL), proton exchange membrane (PEMEL or PEMWE), anion exchange membrane (AEMEL or AEMWE) and solid oxide electrolyzers (SOEC or SOEL). Each technology comes with its own set of performance characteristics, commercial maturity and various advantages and limitations. This report provides an analysis and comparison of the different electrolyzer systems available, covering working mechanisms, materials employed, and system performance, amongst other factors.
Alkaline water electrolyzers (AWE) have long been commercial and used for industrial applications. They are characterized by their lowest capital costs (CapEx) as well as longer stack lifetimes compared to other technologies and are the most mature in terms of manufacturing. PEM electrolyzers (PEMEL) have higher power densities, output hydrogen pressures and faster response times than alkaline systems. This generally makes them better suited to coupling with renewable energy sources directly. PEMEL systems previously lagged behind AWE commercially but are now ready to compete in green hydrogen project installations.
SOEC is a relatively recent electrolyzer technology to reach commercial deployment, driven by advancements in solid oxide fuel cells (SOFC). Operating at high temperatures (>600°C), they offer higher system efficiencies but are expensive and require further improvements. However, their higher temperatures and efficiency compared to low-temperature technologies offer several advantages. For example, SOEC systems can reuse waste process heat and co-electrolyzer H2O and CO2 producing syngas, which makes them well-suited for coupling with industrial applications.
AEMEL is the youngest and least commercially mature technology on the market. AEMEL aims to combine the benefits of AWE and PEMEL systems - low-cost and abundant materials of AWE with the higher efficiencies and dynamic response rates of PEMEL. The number of players developing AEMEL is limited, but it is likely to gain more market players and presence in commercial green hydrogen projects.
While this report focuses on the four technologies discussed above, IDTechEx has also identified novel and alternative electrolyzer technologies. These include CO2, seawater and other novel electrolyzers, such as photoelectrochemical electrolysis. This report provides an overview of these technologies and their commercial development.
Electrolyzer market, manufacturing capacities, commercial system specifications, system & project case studies
IDTechEx has identified many suppliers for the four main electrolyzer technologies, providing lists of players split by technology and region. Manufacturing capacity is expected to increase significantly over the next five years as players look to capture a share of this growing market. IDTechEx analysis shows that European and Chinese companies are particularly active in their plans to expand and grow their electrolyzer manufacturing capacities and capabilities. Significant investment into electrolyzer manufacturing is also expected from North American, India, and other players, which are looking to expand market shares.
The electrolyzer market is currently dominated by alkaline (AWE) and PEM electrolyzer manufacturers with comparatively few companies manufacturing or commercializing SOEC and AEMEL systems. However, the similarity between solid oxide electrolyzers and solid oxide fuel cells as well as shared aspects of AEMEL to AWE and PEMEL systems could provide a significant entry point for these technologies into the green hydrogen market. Certainly, growth in the electrolyzer market, across the four electrolyzer types, will be needed to meet ambitious national and regional targets for green and clean hydrogen production.
This report provides a comprehensive analysis of electrolyzer manufacturers and the overall market. This includes analysis of players by region and technology as well as manufacturing capacity, based on announced plans to install electrolyzer manufacturing facilities globally. Key examples of commercial systems and green hydrogen projects using different technologies are also presented.
Another key aspect of this report is the collection of key performance characteristics for electrolyzer systems. Key metrics for comparing and assessing the performance of an electrolyzer system include system scale (e.g. by production rate of H2), system efficiency (kWh/kg or % LHV), response time, dynamic range, hydrogen purity, output pressure, lifetime, and footprint. IDTechEx collected the different specifications for commercial systems.
Overall market narratives & granular 10-year market forecasts
Ultimately, one of the most important parameters is likely to be levelized cost of hydrogen (LCOH), which is heavily influenced by the price of renewable electricity as well as the capital cost (CapEx) of the green hydrogen plant. IDTechEx's report offers discussions on the interplay between renewable energy, system CapEx and green hydrogen production.
