How is the < 50 m3/h Segment Dominating the Global Alkaline Water Electrolysis Market?
Based on the global alkaline water electrolysis market forecast, < 50 m3/h dominates the industry due to its high demand in small and medium scale hydrogen production application. Also, the dominance of < 50 m3/h can be attributed due to its versatility and suitability in various established applications. Sizeable smaller to medium-sized electrolyzers are suited for decentralized hydrogen applications to address needs such as on-demand industrial gas supply (e.g., laboratories, metal fabrication, electronics), localized energy storage, and multiple pilot projects. Compared to large scale plants, they require less capital investment and have a demonstrated maturity and reliability making them easy adoption opportunities for the first customer, small-scale adoptees.
The ≥ 80 m³/h (or sometimes known as “Above 20 MW” or “large-scale”) type is expected to be the most rapidly growing segment. This increase is largely fueled by the global momentum towards developing a wave of green hydrogen production projects at scale, for use in decarbonizing heavy industries, including power generation and transportation. As economies of scale will be key to unlocking the potential for competitive green hydrogen, the need for more and larger-scale, more efficient electrolyzer units is moving at a breakneck pace.
How is Power Plant Dominating the Global Alkaline Water Electrolysis Market?
Power plants hold the largest application segment in the global alkaline water electrolysis market as they undergo a tremendous transition towards integration of clean energy. Deployable thermal and renewable power plants are increasingly embracing alkaline electrolysis to generate green hydrogen with excess electricity in low-demand hours. That hydrogen may then be used for energy storage or as a fuel, supporting decarbonization. The central installation of power plants allows for the use of high capacity electrolyzers, which are particularly suited to the supply of hydrogen at constant, low marginal costs.
The industrial gases segment is expected to be the fastest-growing application for alkaline water electrolysis. Though today power plants still account for most of the demand, the skyrocketing need for green hydrogen as a feedstock in key industries —including chemicals, metallurgy, and electronics—is propelling exponential expansion. Industries are looking to replace the fossil-fuel-based hydrogen they currently use with green hydrogen, in order to satisfy sustainability goals and decarbonize their carbon footprint, catalyzing the industries desire for on-site production through the use of alkaline electrolyzers.

Such policies are promoting installation and roll-out of alkaline water electrolyzers, helping industries switch towards low-carbon production. Such measures usually include large tax credits (e.g., in the US), direct grants for high-scale projects, and hydrogen blending requirements, significantly lowering the investment risk for producers and project developers
Rising Demand for Green Hydrogen
- With concerns over climate change and fossil fuel reliance growing, industries and governments globally have looked to green hydrogen as a clean energy source. Alkaline water electrolysis is one of the most mature and broadly applied technologies for generating green hydrogen via renewable electricity, and hence, a key technology at the heart of the global energy transition. This demand is strongest in challenging-to-abate industries like transportation, electricity, and heavy industry, where green hydrogen enables decarbonization and achievement of climate targets.
Alkaline water electrolysis Market Restraints
High Operating Cost and Capital Expenditure
- We know from setting up alkaline water electrolysis systems that there is a high barrier to entry with the upfront investment in equipment and infrastructure. Furthermore, for small- and medium-enterprises these costs can be a significant hurdle, particularly when compared to traditional hydrogen production processes such as steam methane reforming. Even though operating costs are lower in the long-term after the initial investment, this requirement of a large upfront fund continues to hinder adoption, especially in developing areas.
Competition from Alternative Wound Care Solution
- Although alkaline electrolysis is very mature and well established, it does have limitations such as reduced response time and decreased efficiency when compared to the state of the art and newer technologies. These technical limitations limit its usability for most dynamic energy applications and make it less competitive for other uses. Additionally, long-term durability requirements and maintenance requirements are still a concern, especially when operating on variable renewable energy inputs.
