Market Overview: Enabling the Green Hydrogen Economy
Electrolyzers are devices that use electricity to split water into hydrogen and oxygen through the process of electrolysis. When powered by renewable energy sources such as solar, wind, or hydropower, electrolyzers produce green hydrogen, a clean energy carrier with minimal carbon footprint.
Hydrogen generated through electrolysis is increasingly used across a wide range of applications, including ammonia production for fertilizers, fuel cells for transportation, power generation, steel manufacturing, and chemical processing. As hydrogen emerges as a cornerstone of future energy systems, electrolyzers are becoming a strategic technology across both developed and emerging economies.
According to analysts, the integration of electrolyzers with renewable energy assets is gaining momentum as it allows storage of excess renewable power and ensures stable, long-term energy utilization. This trend is positioning electrolyzers as a key link between renewable electricity and hard-to-abate sectors.

Key Market Growth Drivers

Rising Demand for Hydrogen as a Clean Fuel
Hydrogen is gaining global attention as a low-emission alternative to fossil fuels. Governments worldwide have announced net-zero targets and carbon-neutral roadmaps, significantly boosting demand for green hydrogen.
Electrolyzers are essential for producing hydrogen at scale, especially as industries seek to decarbonize processes that are difficult to electrify directly. Hydrogen fuel cell vehicles, hydrogen-based power generation, and industrial fuel substitution are key demand drivers.

Preference for Green Ammonia in Fertilizer Production
Ammonia production is one of the largest consumers of hydrogen globally. Traditional ammonia manufacturing relies heavily on fossil fuels and is highly carbon-intensive. Green ammonia, produced using green hydrogen, offers a sustainable alternative.

As agriculture seeks to reduce its environmental footprint, demand for green ammonia is rising, directly driving electrolyzer installations. This shift is particularly important for countries with large agricultural economies.
Supportive Government Policies and Decarbonization Targets
National hydrogen strategies, subsidies, tax incentives, and public-private partnerships are accelerating electrolyzer deployment. Programs supporting renewable energy, green hydrogen hubs, and industrial decarbonization are creating long-term demand visibility for electrolyzer manufacturers.

Technology Trends: Alkaline Electrolyzers Lead the Market

Among the various technologies, alkaline electrolyzers held the largest market share in 2023. Their dominance is attributed to:
• Proven and mature technology
• Lower capital costs compared to alternatives
• High durability and long operational lifespans
Alkaline systems are widely used in large-scale hydrogen production projects, particularly where cost efficiency and reliability are critical. While PEM, SOEC, and AEM electrolyzers are gaining traction due to efficiency and flexibility advantages, alkaline electrolyzers remain the backbone of current installations.
